Sound Military Decision

U.S. NAVAL WAR COLLEGE Newport, Rhode Island

November 30, 1941

SOUND MILITARY DECISION was first published at the Naval War College

in 1936. It included the essential features of THE ESTIMATE OF THE

SITUATION which, since 1910, had been issued at intervals in a series

of revised editions. The new material that was added in 1936 was

intended to assist in enlarging the viewpoint and in broadening the

basis of professional judgment.

Primarily intended for the purposes of the Naval War College, this

work is the cumulative result of years of untiring and loyal effort on

the part of the College staff and student body. Equally important have

been the advice and assistance contributed by other officers of wide

professional experience and attainment.

The objective has been a brief but inclusive treatment of the

fundamentals of the military profession, i.e., the profession of arms.

The emphasis, naturally, is on the exercise of mental effort in the

solution of military problems, more especially in our Navy. An

enormous literature has been consulted, and research has included all

available and pertinent military writings. Care has also been taken to

include, from civil sources, the findings of those authoritative works

which deal with related matters and with the applicable underlying

truths.

In a work of this type and scope, it is manifestly not possible to

illustrate the abstract text by historical examples and analogies.

These are complementary features of the War College resident and

correspondence courses; provision for the necessary historical

background is otherwise the concern of the individual student.

In this edition of SOUND MILITARY DECISION no radical changes have

been made; the revision has been confined to rearrangement and

amplification of the subject matter.

FOREWORD

From the earliest days of recorded history, the facts associated with

military operations of the past have been constantly studied. The

result has been the accumulation of a mass of information from which

conclusions have been drawn as to the causes of success and failure.

Although scattered through countless volumes, and nowhere completely

systematized and classified, this accepted body of knowledge

constitutes the basis for the science of war.

Scientific investigation--that is, the collection, verification, and

classification of facts--follows the recurrent procedure of successive

analysis, hypothesis, theory, and test. The application of this

process to the campaigns of history reveals fundamentals common to

all, irrespective of whether the sphere of action has been land, sea,

or air. In the ceaseless struggle for supremacy between the offense

and the defense, great technological changes have taken place. The

successful conduct of war, however, has always depended on effective

operations for the creation or maintenance of favorable military

situations, whose essential elements have remained unchanged

throughout the years (see page 46).

These fundamental considerations (see page 28), whatever the detailed

form of their presentation, are the basis for the successful conduct

of war. The need of such a basis has been felt from very early times.

It was not, however, until the early part of the Nineteenth Century

that students of warfare appear to have recorded the view that the

conduct of war is susceptible of reduction to scientific analysis, and

that only through a reasoned theory can the true causes of success and

failure be explained.

Such a scientific analysis of any subject has for its chief practical

aim the improvement of the art, or practice, of that subject. Forming

an important part of the science of war are those new developments in

weapons and in other technological fields which, with the passage of

time, have brought about great changes in methods of waging war. It is

only through founding the art of war--the application of the science

of war to actual military situations--on the fundamental truths

discovered through the science of war, that changes in method, due to

technological evolution, can be made most effective.

In preparing for war, the only practicable peacetime tests are usually

restricted to those afforded by examples of the past, by problems such

as chart (map) and board maneuvers, and by fleet and field exercises.

While the military profession can afford to neglect none of them,

such tests can never be conclusive. This fact, however, far from

justifying resort to any other procedure, emphasizes the necessity for

utilization of the scientific method in order to arrive at conclusions

which are as exact as possible.

An exact result is, of course, the aim of all scientific research, but

exactitude necessarily depends on the establishment of correct

relationships among facts which have so far come to light.

Consequently, there is great variation in the degree of accuracy which

actually characterizes the several sciences. If it be maintained that

only those studies which have resulted in exact conclusions may

properly be regarded as sciences, then it can hardly be said that many

sciences, now regarded as such, exist; for the findings of medicine,

biology, chemistry, and even physics are continually being revised in

the light of new data.

The science of war necessarily includes knowledge gained in other

fields. In war, as in medicine or any other practical activity, the

more inclusive and dependable the body of knowledge available as a

basis for action, the more probable it is that the application of this

knowledge, the art (page 1), will be effective.

Realization of these facts has led to renewed emphasis on the

scientific approach to the solution of military problems. The fallacy

of staking the future upon the possible availability of a military

genius in time of need became clear when it was appreciated that more

than one nation, hitherto victorious in arms, had been defeated and

humiliated when genius no longer led its forces.

There followed in the military profession a conviction that, although

extraordinary inherent capacity can be recognized and utilized when

known to exist, it is safer and wiser to develop by training the

highest average of ability in leadership than to trust to untrained

"common sense" or to the possible advent of a genius. History has

abundantly proved the folly of attempting, on any other basis, to cope

with the unpredictable occurrence of genius in the hostile leadership.

With the actual exercise of leadership in war restricted to the

reality of war, there is emphasized the need of peacetime

training--training of subordinates in efficient performance, and, more

important, training of those who will be placed by the State in

positions of responsibility and command.

Campaigns of the Twentieth Century reflect the intensity of mental

training among the armed forces of the greater powers; the planning

and conduct of war have acquired a precision, a swiftness, and a

thoroughness before unknown. The study and analysis of past campaigns,

the sifting of technical details from fundamental truths, and the

shrewd combination of the theoretical and the practical form the basis

of this training.

The proper solution of military problems requires the reaching of

sound decision as to what is to be done. Upon the soundness of the

decision depends, in great part, the effectiveness of the resulting

action. Both are dependent on the possession of a high order of

professional judgment, fortified by knowledge and founded on

experience. Theoretical knowledge supplements experience, and is the

best substitute in its absence. Judgment, the ability to understand

the correct relationship between cause and effect, and to apply that

knowledge under varying circumstances, is essential to good

leadership. Professional judgment is inherently strengthened by mental

exercise in the application of logical processes to the solution of

military problems.

The approach, presented herein, to the solution of military problems

is intended to assist the military profession in reaching sound

decisions as to (1) the selection of its correct objectives, the ends

toward which its action is to be directed under varying circumstances;

(2) planning the detailed operations required; (3) transmitting the

intent so clearly as to ensure inauguration of well-coordinated

action; and (4) the effective supervision of such action.

The student of war will find in these pages a fundamental military

philosophy whose roots go down to very ancient times. In the technique

described for the solution of military problems, experienced officers

will recognize a system with which they are already familiar. This

system, constantly under study to improve its details, has been in use

in our military Services for many years.

The foundation of this philosophy and of the system for its practical

utilization rests on the concept of relative or proportional values.

In the military environment, change, rather than stability, is

especially to be expected, and the relationships existing among the

essential elements of a military situation are, in fact, the

significant values. Such values, themselves, vary with the viewpoint

of the person concerned. Accordingly, because of the difference in

objectives (defined above), what is strategy as viewed by a commander

on a higher echelon may have more of a tactical aspect to those on a

lower (page 10). Immediate objectives and ultimate objectives (page

54) can scarcely be understood in their true proportions unless the

point of reference is clear. The point of view of the commander, as

established by the position he occupies in the chain of command, is,

therefore, to be taken into consideration in every phase of the

solution of a problem,--in the determination of the appropriate effect

desired (page 43), of relative fighting strength (page 35), and of

courses of action and the detailed operations pertaining thereto (page

88).

On the basis of these facts, instantaneous and easy understanding of

all the elements involved is not to be expected. Were such

understanding possible, the expert conduct of war would be one of the

easiest, instead of one of the most difficult, of human activities. It

is only through a gradual assimilation of its fundamentals that the

profession of arms is to be mastered. A process of true education is

involved,--that of enlarging the viewpoint and broadening the basis of

professional judgment (see page i),--and its essentials are the proper

foundation for any system of self-improvement in the exercise of

mental power. There is no easy road to the goal of military effort.

Part I, hereafter, discusses professional judgment in its basic

relation to the successful conduct of war. This treatment examines the

responsibilities of the armed forces, discusses the role of the

commander, indicates the natural mental processes employed in the

solution of military problems, formulates and explains the Fundamental

Military Principle, and concludes with an outline of the procedure for

its further application in Parts II and III.

Part II is concerned with the solution of the problems encountered

during the planning stage.

Part III discusses the execution of the plan,--the directives and the

supervision of the action,--but the treatment as to details is chiefly

from the standpoint of the mental effort. During hostilities the vital

issues which hinge on alert supervision create an accentuated demand

for the intelligent exercise of professional judgment. Its possession

to a highly developed degree and its exercise on a foundation of

knowledge and experience, are prerequisite to attainment of the

highest standards in the conduct of war.

The following pages are intended, therefore, to provide a fundamental

basis upon which the commander, by thoughtful study and reflection,

may develop his professional judgment to the end that its exercise

result in sound military decision, essential alike to wise planning

and to consistently effective action.

PART I

PROFESSIONAL JUDGMENT IN ITS RELATION TO

THE SUCCESSFUL CONDUCT OF WAR

CHAPTER I

COMMAND AND ITS PROBLEMS

The Foreword, preceding, has explained the scientific

approach to the solution of military problems. It has been

brought to notice that the science of war can be utilized to

further sound military decision and, so, to improve the

practice of war, i.e., the art of war, whether under assumed

or actual conditions. The Foreword has also stressed the

importance of education for the development of judgment in

the application of mental power to the solution of military

problems.

Chapter I, which now follows, deals with the armed forces in

their relation to national policy, and discusses,

specifically, the role of the commander with respect to the

use of mental power as a recognized component of fighting

strength. Emphasis is placed on the important subjects of

military strategy and tactics, unity of effort, the chain of

command, authority and responsibility, organization, mutual

understanding, loyalty, and indoctrination.

The Implementation of National Policy. Organized government exists for

the purpose of bringing into systematic union the individuals of a

State for the attainment of common ends. The primary national

objective (page 3) is the ensurance of envisaged prosperity and of

essential security for the social system which is the fundamental

basis of the community. Whatever the form of government, the power and

authority of the State are vested in an individual, or in a grouping

of individuals, whose voice is the voice of the State. In the

prosecution of the chief aim of organized government, the State

crystallizes the many conflicting desires and views of its people into

policies, internal and external. Each policy is a method of procedure

for attaining one or more national objectives.

Internal policies are rendered effective by enforcement of the laws of

the State.

External policies, to become effective, require recognition by other

States, tacitly or by agreement. When there is conflict between the

policies of one State and those of another, peaceful means of

settlement are usually sought.

If peaceful (diplomatic) means fail to settle the point at issue, the

State abandons the policy in question, defers action to enforce it, or

adopts stronger measures. Such measures may take the form of

psychological, political, or economic pressure. They may even include

the threat to employ armed force before actually resorting to the

imposition of physical violence. During actual hostilities, also,

every means of pressure known to man, in addition to physical

violence, may be employed.

Whether the use of armed force to impose or to resist the imposition

of policy constitutes a legal state of war is a political question

which does not affect the tasks the armed forces may be called on to

perform. War, therefore, is to be understood herein as any condition

in which one State employs physical violence against another, or

against an organized part of itself which may be in rebellion.

By agreement among nations, effort has been made to discountenance

aggressive warfare. The distinction between aggression and

self-defense is, however, not a matter of agreement. War is still

employed as an instrument of national policy. No nation has, as yet,

manifested willingness to relinquish the right to employ armed force

in resisting aggression, nor the right to decide what constitutes

self-defense. States still maintain and employ armed forces as a means

of promoting and expanding, as well as of defending, their welfare and

interests.

The Primary Function of the Armed Forces. Whether war is an ethical

institution is not a matter within the purview of the armed forces.

Their primary function is, when called upon to do so, to support and,

within the sphere of military effort, to enforce the policy of the

State. The performance of this function constitutes the chief reason

for their existence.

The fundamental objective of the armed forces is, therefore, the

reduction of the opposing will to resist. It is attained through the

use of actual physical violence or the threat thereof (page 7). This

fact constitutes the underlying motive of every military plan, whether

for the conduct of a minor or contributory operation, or for the

prosecution of a major campaign. The final outcome is dependent on

ability to isolate, occupy, or otherwise control the territory of the

enemy, for land is the natural habitat of man (page 46). Since

opposition is to be expected, the military problem is primarily

concerned with the application of power--mental, moral, and

physical--in overcoming resistance, or in exerting effort to resist.

The application of power implies effort, i.e., the exertion of

strength. The mental, moral, and physical power at the disposal of the

armed forces depends on the effort which can be exerted by the human

and material components of their fighting strength.

The skillful employment of fighting strength, as a weapon more

effective than the enemy's under a given set of circumstances, is the

goal toward which the armed forces direct their effort. The elements

of the material component--arms, ammunition, and other equipment--are

indispensable. They are impotent, however, without the direction and

energy supplied by the human component, its moral and mental elements

nicely balanced and judiciously compounded with physical fitness. A

true concept of the art of war will insist that the necessity for the

achievement of a high standard of technical and administrative skill

not be permitted to outweigh the need for maximum development of other

mental attainments, and of the moral components of fighting strength.

The moral elements include all the essential attributes of personal

character, and more especially those qualities of courage, loyalty,

decisiveness, modesty, patience, tolerance of the opinions of others,

and fearlessness of responsibility which are characteristics of true

military leadership. The maintenance of a high ethical standard is

essential to the establishment and continuance of mutual confidence.

The qualifications essential to the proper application of the mental

elements include a creative imagination and the ability to think and

to reason logically, fortified by practical experience and by a

knowledge of the science of war. An unmistakable mark of mental

maturity is the ability to distinguish between preconceived ideas and

fundamental knowledge. Intellectual honesty, unimpaired by the

influence of tradition, prejudice, or emotion, is the essential basis

for the effective employment of mental power.

The numerical size of the armed forces, in their correct perspective

as an instrument of the State, as well as the extent to which they are

supplied with material components of fighting strength, are matters to

be determined by the State after consultation with the responsible

military authorities. The development of the essential military

qualities of the instrument is the special charge of the armed forces.

It is their task to weld the assemblage of men, armed and maintained

by the State, into an harmonious whole, skilled in technique and

imbued with a psychological and mental attitude which will not admit

that any obstacle is insuperable.

The Advisory Function. Understanding between the civil representatives

of the State and the leaders of the armed forces is manifestly

essential to the coordination of national policy with the power to

enforce it. Therefore, if serious omissions and the adoption of

ill-advised measures are to be avoided, it is necessary that wise

professional counsel be available to the State. While military

strategy may determine whether the aims of policy are possible of

attainment, policy may, beforehand, determine largely the success or

failure of military strategy. It behooves policy to ensure not only

that military strategy pursue appropriate aims, but that the work of

strategy be allotted adequate means, and be undertaken under the most

favorable conditions.

These considerations require that the military profession be

qualified, through the possession of mental power, clear vision, and

capacity for expression, to advise the State in military matters.

There is thus accentuated the need for mental training, as set forth

previously in the Foreword.

Military Strategy and Tactics. Military strategy as distinguished by

objectives (page 3) representing a larger, further, or more

fundamental goal, is differentiated from tactics in that the latter is

concerned with a more immediate or local aim, which should in turn

permit strategy to accomplish its further objective.

Consequently, every military situation has both strategical and

tactical aspects. The nature of the objectives to be attained at a

particular time, and the action to be taken to that end, may be

governed chiefly by strategical, or chiefly by tactical,

considerations. Whether an operation is distinctively strategical or

tactical will depend, from the standpoint of the commander concerned,

on the end which he has in view.

To attain its objective, strategy uses force (or threatens such use)

(see page 8) as applied by tactics; tactics employed for a purpose

other than that of contributing to the aims of strategy is unsound.

Proper tactics, therefore, has a strategic background. Definition of

tactics as the art of handling troops or ships in battle, or in the

immediate presence of the enemy, is not all-inclusive. Such a view

infers that the field of battle is the only province of tactics, or

that strategy abdicates when tactics comes to the fore.

Actually, while tactical considerations may predominate during battle,

their influence is not confined to the immediate presence of the

enemy. Tactical dispositions are frequently adopted for convenience,

for time saving, or for other reasons, long before entry into the

immediate presence of the enemy. Nor do strategical considerations end

when battle is joined. Tactics, unguided by strategy, might blindly

make sacrifices merely to remain victor on a field of struggle. But

strategy looks beyond, in order to make the gains of tactics accord

with the strategic aim. Strategy and tactics are inseparable.

It is thus the duty of tactics to ensure that its results are

appropriate to the strategic aim, and the duty of strategy to place at

the disposal of tactics the power appropriate to the results demanded.

The latter consideration imposes upon strategy the requirement that

the prescribed aim be possible of attainment with the power that can

be made available.

Consequently, while the attainment of the aims of strategy, generally

depends upon the results gained by tactics, strategy is initially

responsible for the success of tactics. It is therefore in the

province of strategy to ensure that the attainment of tactical

objectives furthers, exclusively, the aims of strategy, and also that

the tactical struggle be initiated under conditions favorable for the

attainment of the designated objectives.

Command of the Armed Forces. The initial requisite to the effective

use of the armed forces is an agency authorized to direct them.

Command directs the armed forces. It is vitalized and personified in

the commander, the human directing head, both of the whole and of

organized groupings in descending scale of importance. Its

responsibility, during peace, is the perfection of the armed forces to

the point of readiness for war and, during the conflict, their

effective employment.

Training for command, to be effective, is necessarily dependent upon

an understanding of the position occupied by the commander, and of the

role which he plays. Accordingly, this understanding is an essential

in the study of that aspect of command training which has as its

purpose the development of ability to reach sound decision.

The ideal of military command combines the best of human qualities

with sound knowledge of the capabilities and limitations of the armed

forces. It recognizes in war a form of human activity whose conduct,

like that of all other human activities, is subject to natural law. It

applies to the mastery of the problems of war, therefore, the natural

mental processes of human thought (see Chapter II); it adapts these

natural processes to a specific purpose, and consciously develops

their use to the maximum degree for the attainment of this end. As

command ascends the scale, its viewpoint broadens. Experience and

added knowledge, with increasing authority and responsibility, lead to

a concept of war more and more comprehensive, with the resultant

growth in ability to evolve and put into effect a general plan for

the effective control of collective effort.

Unity of Effort. An objective is best attained by effective

application of properly directed effort, exerted by a single

individual or by groups of individuals. Where individuals are

collectively concerned, unity of effort is the most important single

factor contributory to the common success. The basic condition to be

sought by the armed forces is an harmonious whole, capable of putting

forth combined effort, intensified in strength because of the

collective feature, and rendered effective by its unity.

The Chain of Command. Within the limits of human capacity, an

organization can exert its combined effort with greater effect the

more closely the exercise of command represents the act of a single

competent commander. To divide the supreme command in any locality, or

to vest it in a body rather than in an individual, is necessarily to

diffuse responsibility. In that degree there is then incurred the

danger, through confusion of wills and ideas, of delaying decision and

of creating corresponding diffusion of effort.

Realization of this danger has led the military profession to entrust

command, subject to justifiable exceptions (see page 71), to a single

head, while ensuring, by careful selection and training of personnel,

that competent individuals are available for this duty. Although this

method is in seeming conflict with the restriction imposed by

recognized limitations of human capacity, the difficulty is

effectively met through the chain of command, whereby responsibility

is assigned and authority is transmitted without lessening of ultimate

responsibility. Responsibility and authority, the latter properly

apportioned to the former, are inseparably inherent in command, and

may not justifiably be severed from one another.

In the abstract, the chain of command consists of a series of links,

through which responsibility and authority are transmitted. The

supreme commander is thus linked with his successively subordinate

commanders, and all are disposed on, so to speak, a vertical series of

levels, each constituting an echelon of command.

By means of the chain of command, a commander is enabled to require of

his immediate subordinates an expenditure of effort which, in the

aggregate, will ensure the attainment of his own objective (page 3).

He thus assigns tasks to his immediate subordinates, whom he holds

directly responsible for their execution without, however, divesting

himself of any part of his initial responsibility. The accomplishment

of each of these assigned tasks will involve the attainment of an

objective, necessarily less in scope than that of the immediate

superior but a contribution to the attainment of the latter.

The character and magnitude of the objective of the highest echelon

involved will have considerable bearing upon the number of echelons

required for its attainment. Whatever the number, a commander on a

particular echelon occupies the position of an immediate subordinate

to a commander on the next higher echelon, and that of an immediate

superior with relation to a commander on the next lower echelon.

Within these confines, authority is exercised and accomplishment

exacted, both to the extent calculated to ensure unity of effort.

There may frequently be found two or more commanders occupying

coordinate positions on the same echelon, all with the same immediate

superior, and all charged with loyalty to him and to each other in the

attainment of a common objective. In no case, however, will a

commander be directly answerable to more than one immediate superior

for the performance of the same duty. Thus is fulfilled the

requirement that the command, although relatively narrower in scope as

the scale is descended, be reposed in a single head.

The experience gained and the knowledge acquired during early service

on the lower echelons provide a basis for later expansion of

viewpoint, a better understanding of the position occupied by the

subordinate and of the obligations of higher command, including its

dependence on subordinates. As the echelons of command are ascended,

the details involved become more and more numerous, because of the

increased scope of the problems. On the higher echelons, therefore,

staff assistance is provided so that the commander may be left free to

consider matters in their major aspects. The staff of a commander is

not, however, a part of the chain of command; its members, as such,

exercise no independent authority.

A chain of command is not created by the subdivision of the officer

corps into grades on a basis of relative rank. Such subdivision is for

the purpose of classification from the standpoint of potential

competency and capacity for responsibility, and carries no authority

to command by virtue of rank alone. Organization, systematized

connection for a specific purpose, is first necessary.

The armed forces, during peace, are usually subdivided into permanent

major organizations for the purpose of attaining and maintaining

readiness for action. From the several grades of the officer corps, a

permanent chain of command is instituted by the process of organization,

the supreme command being reposed in a commander-in-chief. The basis of

the permanent organization is that chosen as best suited to attain and

maintain readiness. Its choice requires consideration of many factors,

such as the types of weapons and vessels, their intended uses, and their

capabilities, severally and in combination. Further specific demands are

met by temporary arrangements effected through "task organization".

Whether the organization be permanent or temporary, its establishment

places in effect a chain of command applicable to that organization

throughout its continuance.

Habitual and studied adherence to the chain of command in

administrative matters, in consultation, in the exchange of

information, and in the issue of directives is essential to mutual

understanding, and therefore to unity of effort. The right of a

commander, however, because of the responsibility he shoulders, to

deal directly with subordinates more than one echelon removed is not

relinquished because of the existence of the chain of command.

Circumstances may arise which require him to issue orders directly to

any person under his command. Fully aware, however, of the value of

unity of effort, and recognizing that failure to deal through his

immediate subordinate, no matter what the exigency, cannot but tend to

weaken the chain of command, he will, as soon as the state of the

emergency permits, inform intervening commanders of the action he has

been compelled to take.

Mutual Understanding. The chain of command, though providing the

necessary linkage, does not of itself ensure that the command

organization will be adequate, nor can it ensure that unity of effort

will result. To meet the requirement of adequacy, there is needed in

the person of each commander not only the ability to arrive at sound

military decision, to plan, and to direct the operations of his

command, but also an appreciation of the position which he occupies in

his relationship to his immediate superior, on the one hand, and to

his own immediate subordinates on the other. To meet the requirement

of unity of effort, it is also essential that there exist a state of

mutual understanding throughout the chain of command.

Loyalty is not merely a moral virtue; it is a great military

necessity. To establish and to cultivate a state of mutual

understanding from which will flow mutual loyalty born of mutual

confidence (page 9) are prime obligations of command. Within the

limits of responsibility and resultant authority, individual

initiative will follow. On a foundation of intelligent cooperation and

resolute determination, the acts of the lowest commander will be in

accordance with the desires of the highest. This, in effect, will

constitute unity of effort, accomplished through the vesting of

command in a single head.

The final aim of mutual understanding is attained when, in the absence

of specific instructions, each subordinate commander in the chain acts

instinctively as his immediate superior, if present, would have him

act, and also cooperates intelligently with commanders occupying

coordinate positions on the same echelon. For this reason there is

need, on all echelons, of a complete grasp of the significance of the

relationship between immediate superior and immediate subordinate, and

of the obligations of each to the other.

The proper relationship is such that a subordinate, even though

separated from his commander, can confidently take action as if the

latter were present. To this end, the competent commander will earlier

have cultivated the personal relationship between his immediate

superior and himself, and between himself and his subordinates. It is

through such close relationship that mutual understanding is best

developed and harmony promoted, so that intelligent and cordial unity

of effort may exist among the personnel of a command.

The commander, however competent, necessarily relies on his

subordinates. Recognizing the psychological factors involved, he will

therefore manifest confidence in their abilities, display sympathetic

interest in their efforts, and evince pride in their achievements. He

will also exercise patience with the mistakes which will inevitably

occur, without condonement, however, of disaffection, neglect, or

carelessness. The commander may reasonably expect, by the same token,

that this attitude will characterize his immediate superior.

In the absence of his superior, and faced with a changing situation, a

commander may be forced to the conclusion that his assigned task

requires modification or alteration. Conditions permitting, he will of

course communicate with proper authority, and will make constructive

representations. If he is without adequate communications facilities,

or if circumstances have imposed restrictions on communications

facilities otherwise available, he takes action according to the

dictates of his own judgment, guided by the known views of his

superior. On occasions when he believes that the immediate situation

so requires, he may even depart from his instructions. He realizes

that in so doing he accepts the gravest of military responsibilities.

At the same time, however, he recognizes that to fail to take the

indicated action may disclose a lack of the higher qualities of

courage, judgment, initiative, and loyalty (page 9). He will, of

course inform his superior of his action at the first available

opportunity. In the meantime, he has been enabled to act intelligently

and fearlessly because of the existence of a state of mutual

understanding.

Indoctrination. Both the necessary process and the final result of

establishing a state of mutual understanding are sometimes known as

indoctrination.

The word carries the dual meaning of "the act of indoctrinating" and

"the state of being indoctrinated". In common with the word doctrine,

it has its root in the Latin verb which means "to teach". A doctrine,

in its pure meaning, is that which is taught, or set forth for

acceptance or belief.

It does not follow that every doctrine is necessarily sound, nor that

it is founded on conviction reached as the result of intelligent

thought. Nor is the encouragement of a belief, by means of the spread

of a doctrine, necessarily inspired by good motives. The preaching of

doctrine known to be false is frequently encountered in many human

activities. The deliberate spread of false propaganda is an example.

But, whatever the motive and whether the doctrine be sound or false,

the act of indoctrination is intended to shape opinion and thus

influence action.

Manifestly, to be along permanently useful lines, indoctrination flows

from sound philosophy, i.e., is rooted in truth. All teachings, all

opinions that may be advanced, all expressions of viewpoint, i.e., all

doctrine, is therefore to be scrutinized, first from the standpoint of

validity, and then from that of usefulness of application. It is the

responsibility of command to ensure that these conditions are met

before doctrine is pronounced.

Military doctrine, in its broad sense, is a digest of the accepted

beliefs of the military profession. In a narrower sense a military

doctrine may be confined to the views of a single commander on a

specific subject. The object of military doctrine, however, is always

to furnish a basis for mutual understanding to the end that prompt and

harmonious action by subordinate commanders may ensue without the

necessity for referring every problem to superior authority before

taking action (page 15). Doctrine thus provides a basis for action in

possible situations when, for whatever reason, precise instructions

have not been issued.

The term "doctrine" is inappropriate as a description of the content

of orders or instructions prescribing specific methods of action for a

particular tactical operation in a situation existent or assumed under

circumstances of the moment. The precise instructions thus issued,

though they may be the result of doctrine, and may themselves

constitute a basis for development of doctrine, are manifestly of the

nature of something ordered rather than presented as authoritative

opinion.

In the broad field of the conduct of war, with its diversified

demands, a common viewpoint as to the application of fundamentals is

an essential to unity of effort. If the members of the military

profession have this common viewpoint, their reasoned beliefs as to

the best general methods of waging a particular war may be expected

more nearly to approach unanimity. The attainment of unity of effort

therefore calls for an understanding of fundamentals (page i), a basic

indoctrination which is not only sound but also common to all

commanders of the chain of command.

Wars come and go. Their effects are painful, but when their wounds are

healed mankind is prone to forget and to hope, even to assume, that

peace will henceforth be unbroken. Psychological and economic forces

then not infrequently impel the State to subordinate the national

defense in favor of other interests. During such periods the burdens

of command are enlarged. Its responsibility is not lessened, but the

means for effective discharge thereof are withheld.

The effective conduct of war thus requires that understanding exist

(see pages 9 and 10) between the civil representatives of the State

and the leaders of the armed forces in the coordination of policy with

the preparation and the use of power to enforce it. Of the leaders of

the armed forces, as a whole or in combinations, such conduct of war

demands the expression of the highest of human qualities, coupled with

intimate knowledge of fundamentals, an appreciation of the capacities

and limitations of the technique, and the ability to fit the

practical details into the general plan in their true relation

thereto.

The need for these qualities is manifestly not restricted to the hour

of supreme test, when the weapon of the State, the armed forces, is

wielded with hostile purpose. The forging of the weapon, and its

adequate preparation for use, are not matters susceptible of deferment

until the crucial hour. The exacting requirements of war are

essentially such as to preclude the readiness of the requisite

intricate instrument and its skillful use without previous studied

effort during peace.

It follows that where the peacetime effort of the armed forces is

directed toward the attainment of a war time objective of a specific,

rather than of a vaguely general character, and the necessary

components of fighting strength are provided accordingly, the

readiness of the instrument is more likely to be adequate, and the

application of power more likely to be successful. History records, as

facts, that certain States have given their armed forces great

stimulus by early clear definition of policy while, in other cases,

failures and disappointments have resulted from a lack thereof.

Military problems are not confined to those presented after war is

begun.

Mental power (see pages 8 and 9), which includes the ability to solve

military problems in peace and in war and to arrive at sound

decisions, is a recognized essential component of fighting strength

because it is the source of professional judgment. The development of

such ability in those who may be charged with the successful conduct

of war (page 4) may not safely be postponed.

CHAPTER II

MENTAL PROCESSES AND HUMAN TENDENCIES

The discussion in Chapter II deals, first, with the natural

mental processes employed by the normal mature human being

before taking deliberate action.

With the necessity for logical thought thus established, there

arises a need for valid statements of cause and effect, i.e.,

of relationships resulting from the operation of natural laws,

for use as reliable rules of action. The discussion of this

subject explains the dangers inherent in the use of faulty

rules, emphasizes the role played by the various factors

applicable in particular cases, and describes the method of

formulating reliable rules, i.e., principles.

All living beings and their surroundings are understood, on the basis

of informed authority, to be governed in their characteristic

activities by natural law (page 11). The natural forces inherent in

living things and in their environment are continually reacting upon

each other, either maintaining the existing condition or creating a

new one, each of which is a situation or state of affairs. There is

thus always a relationship (page 3) existing between such natural

forces and the resultant condition which they produce. The natural

forces are causes; the resultant conditions are effects.

It is a recognized natural phenomenon that every effect is the result

of a certain cause, or of a combination of causes, and that each

effect is itself, in turn, the cause of additional effects. Action and

reaction are the basis of natural law. Cause and effect, the latter

being the cause of further effects, follow each other in ceaseless

succession in the world of human affairs.

Except by putting proper natural causes into action, it is impossible

to produce the effect desired. It follows that specific knowledge of

causes is necessary for the planned production of specific effects.

Toward the accumulation of such knowledge the methods of science

(pages 1 and 2) are constantly directed.

The uncertainties of war are largely the outgrowth of the fact that

the minds of men are pitted against one other. Because of this, a

knowledge of the manner in which the human mind seeks its way out of

difficulties is a great military asset. Consideration is next given,

therefore, to the natural mental processes employed (page 11) and to

certain human tendencies which have been known to militate against

their successful employment.

The mental processes employed by the normal mature human being before

taking deliberate action, or in making studied provision for possible

future action, are natural procedures, in that they employ the

intellectual powers bestowed by nature, without artificial

modification or embellishment.

When the individual concerned has a background of adequate knowledge

and experience, his ability to solve problems is limited only by his

native intellectual endowment. That he falls short does not

necessarily indicate, however, that the limit of native endowment has

been reached. It happens frequently that latent powers have not been

cultivated, or have not been utilized.

A problem is, by definition, a perplexing question. In any human

activity, a problem appears when a perplexity arises as to a way out

of a difficulty inherent in a situation. The question involved then

is, what is a way, more especially the best way, out of the seeming

difficulty?

To determine the best way out of the difficulty, i.e., the best

solution of the problem, involves:

(1) The establishment of the proper basis for the

solution of the problem,

(2) The actual solution of the problem through the

employment of the reasoning power in the consideration of

various possible solutions and the selection of the best

solution, and

(3) The conclusion, i.e., the decision, embodying the best

solution.

Considered in greater detail, the process has its inception in a

combination of circumstances, existent or assumed, which, constitutes

a situation. No problem will result however, unless the situation

involves an apparent difficulty. Even in such a case, a problem will

result only if such involvement exists and gives rise to a perplexity

as to a way, more especially as to the best way, out of the seeming

difficulty.

The problem will require solution only when accompanied by an

incentive which demands a changed situation or resistance against a

threatened change. A recognition of the incentive thus necessarily

involves realization of a desire or need to maintain the existing

situation or to change it into a new one.

Such realization may come on the initiative of the person confronted

with the situation, or because he has received instructions from

someone in authority. In either case, the effect so indicated is the

outcome of a desire for change or for resisting change, and may

therefore be regarded properly as an effect desired (page 19).

As so far outlined, therefore, the establishment of the correct basis

for the solution of the problem involves (1) a grasp of the salient

features of the situation, (2) a recognition of the incentive, and (3)

an appreciation of the effect desired.

The "appropriate" effect desired will necessarily be suitable to the

further effects (page 19) which are inherent in the situation. An

effect to be attained is accepted as appropriate when, after due

examination, its relationship with the further effects involved, in

all their pertinent implications, has been found to be in accordance

with the dictates of sound judgment.

The establishment of the basis for the solution of the problem will

also require an understanding of the resources involved, as influenced

by the conditions obtaining, for the maintenance of the existing

situation or for the creation of a new one.

The resources available, as influenced by the conditions obtaining,

are correctly considered on a relative basis as compared to those of

any persons who may oppose the effort.

With the basis for the solution of the problem established in this

manner, the actual solution involves the consideration of one or more

plans, i.e., proposed methods of procedure, and the selection of the

one considered to be the best.

The person concerned, taking cognizance of the present condition,

i.e., the existing situation, first considers whether this situation,

if maintained, will be suitable to the appropriate effect desired.

Then, unless satisfied that he desires no change, he creates one or

more images of future conditions, i.e., mental pictures of new

situations, which will also be suitable to this end. The maintenance

of the existing situation, or the creation of a new one, will in each

case involve a plan.

Necessarily, each such plan includes provision for (1) an effect to be

produced by the person solving the problem, which effect will be the

maintenance of the existing situation or the creation of a new one as

visualized by himself, and (2) the action required to produce this

effect and so to attain the appropriate effect desired, already

established as an essential part of the basis of his problem.

After systematic examination of such plans, those retained for further

consideration can be subjected to a comparison as to their relative

merits.

The best plan, selected accordingly, is then incorporated into a

decision as to the procedure to be adopted.

This decision is then available as a general plan, or may be developed

into one, to serve as a basis if necessary for a more detailed plan

for the attainment of the appropriate effect desired.

Later development, herein, of the details of this procedure will

disclose many ramifications. The treatment, so far, points to the fact

that the best method of reaching sound decision is through systematic

thought which employs logic, i.e., sound reasoning, as its machinery.

The Necessity for Logical Thought. Logical thought separates the

rational from the irrational. Its use avoids the wastefulness of the

trial-and-error method. By its insistent employment, dormant powers of

reasoning are awakened, and the danger that attends instinctive,

spontaneous, impulsive, or emotional acceptance of conclusions (page

9) is lessened. The evil effects of an inclination to dodge the issue

or of a disinclination to face the facts are thus also avoided. The

fallacy of employing the reasoning power to justify conclusions

already reached, whether on the basis of tradition or habit, or

because of the bias or bent of a school of thought, or because of the

tendency of human nature to accept plausible suggestions, is also made

apparent. Through the deliberate practice of testing and weighing, the

faculty of arriving swiftly at accurate decisions is strengthened and

is brought more quickly into play when time is a matter of immediate

concern.

Principles in their Relation to Logical Thought. Because of the

necessity for the exercise of judgment (page 3) in the systematic

arrangement of thought, the relationship between cause and effect, as

expressed in principles, is of great assistance in applying logical

processes to the problems of human life.

A principle establishes a correct relation between cause and effect.

The word, derived from the Latin "principium", meaning a foundation,

beginning, source, origin, or cause, has, because a cause implies an

effect, acquired in correct usage the significance of a true statement

of relationship between cause and effect. A principle, so formulated,

is a natural law (page 19) because it expresses a fact of nature; it

thus becomes a reliable rule of action and may be confidently adopted

as a governing law of conduct. If basic in its field, such a rule or

law becomes a general or fundamental principle with respect thereto;

each such basic truth may be the basis for the determination of many

corollary or subordinate principles dealing with the details of the

particular subject.

The formulation of a principle, therefore, requires the determination

of the causes that generate a particular effect (or effects), and the

accurate expression of the resultant relationship. Such expression

frequently takes the form of a proportion. In the mathematical

sciences the proportion may represent a precise balance; its statement

may be an exact formula. In other sciences, a definite relationship

between cause and effect has likewise been established in many cases,

though not always with mathematical precision. Comparable exactitude

has not been attained, in some cases, because the field has not been

so thoroughly explored; moreover, greater difficulty is experienced,

at times, in isolating the cause, or causes. The balance represented

by such equations, therefore, is based on quantities whose weights

vary within wide ranges. (See page 3.)

Human conduct does not lend itself to analysis as readily as do

mathematical and physical phenomena. The advance in the psychological

and sociological sciences is not so marked as in the physical, and the

actions and reactions of the mind of man have not yet proved to be

susceptible of reduction to exact formulae. Nevertheless, man, in his

intuitive search for valid guides for his own action, has been able,

with the advance of time, greatly to improve his own lot through the

medium of the scientific approach to human problems.

The insistent search of the human mind for reliable rules of action is

a recognized natural phenomenon. As understood on the basis of expert

investigation of the subject, this trait results from the recognition,

conscious or otherwise, by countless generations of mankind, of the

relationships between cause and effect as evidenced in the workings of

the laws of nature (page 22). A logical outcome, therefore, of

experience, this instinctive demand of the mind constitutes a force

which defies opposition. Properly utilized, this force affords a

powerful and natural aid in the solution of problems.

Inasmuch as a valid rule, or principle, is of great assistance in

arriving at sound decisions and in formulating effective plans (see

page 22), this demand for reliable guides is logical, as well as

natural. In any event, the demand for such guidance, if not met by

provision for reliable rules of action, may result in the adoption of

faulty rules, with frequent unfortunate consequences.

The formulation of principles, already referred to in this connection,

constitutes in itself a recognized problem (see also page 27) of great

difficulty; for it is a human failing to avoid the mental effort

involved in thinking through such a problem, and to rely on rules

whose plausibility and seeming simplicity are frequently a measure of

their incompleteness and inaccuracy.

Since the earliest days, man has attempted to formulate the

relationships between causes and effects without, however, always

possessing the specific knowledge essential to accuracy. Pithy

statements have always had great appeal to man, as evidenced by the

existence of proverbs, maxims, and adages preserved from times of

great antiquity. Frequently, however, such statements are not

expressive of the truth. Sometimes, again, they state facts, without,

nevertheless, expressing the whole truth.

Only when the relationship between cause and effect has been

demonstrated to be always true can the trained, inquiring mind receive

its statement as a valid guide, acceptable as a principle in the light

of the knowledge of the day.

To rely upon rules of action which do not express the whole truth is

to court the danger of encountering exceptions which may entail

serious consequences. The value of those rules known to be

inexpressive of the whole truth lies in the fact that they may invite

attention to circumstances which are sometimes encountered, or may

suggest methods of action which are sometimes appropriate. Danger lies

in the fact that such rules may fail to give proper emphasis to other

circumstances or other methods which are encountered or are more

appropriate in other cases.

Such a rule may fail to consider the entire problem. Its use,

therefore, implies the necessity of recognizing cases to which it is

not applicable. This may frequently be difficult in the active

operations of war, when nervous strain and the urgency of events are

handicaps to quick and accurate thinking (see page 22).

To express the whole truth, a rule of action calls to attention all

circumstances, or causes, which may ever influence the result. The

saying that "the exception proves the rule" is properly interpreted

only in the older sense that an exception "tests" the rule, indicating

by the mere fact of exception that the rule is to such extent

incomplete.

Subject to variations of phraseology, the old adage "circumstances

alter cases" is the sole reliable and fundamental rule of action. A

corresponding maxim of the military profession, "It depends on the

situation", has its root in recognition of the same fact, i.e., that

the action taken in any situation depends, properly, on the

circumstances of the case, and that the relationship between cause and

effect (page 22) is always the governing consideration. The principles

deduced hereafter (Chapter III) have these irrefutable findings as

their foundation.

Factors. A situation is by definition (page 20) a combination of

circumstances, which are the effects of certain causes. To these

causes, the term "factors", long in use in the military profession, is

customarily applied in many other activities. Through their influence

as causes, these factors operate to produce, as their effects, the

circumstances which, in combination, constitute the situation. A

combination of factors, therefore, gives to each situation its

distinctive character, differentiating it from other situations.

To maintain an existing situation, it is necessary to preserve, in

total effect, the influence of factors already present, or to

introduce new factors to offset the influence of any which tend to

cause a change. To change the situation, it is necessary to introduce

factors which will exert the desired influence; or, change may be

effected by altering the influence of factors already present. To say,

therefore, that "It depends on the situation", as in the maxim cited

(above), is to state that under all circumstances, the proper action

depends on, or is determined by, the influence of the factors

involved. Any valid rule, or principle, will accordingly take into

account the factors applicable to the case.

The application of any rule will similarly take into account the

influence of the particular factors involved. The danger of the

application of such factors to all circumstances, without due

circumspection as to their value in the existing situation, lies in

the fact that, in any particular combination of circumstances, they do

not necessarily carry equal weight.

If this view be accepted, it follows that in many situations certain

factors may, after mature deliberation, be rejected, or relegated to a

relatively inferior status, without detracting from their potential

value as fundamental considerations (page 1) in all situations.

Value and Limitations of Lists of Principles of War. The human

preference for catchwords has, by many writers on the science and art

of war, been extended to the attempted condensation of a principle or

of several principles into a single all-inclusive word or phrase. As

a result, varying lists of abstract nouns and phrases have been

advanced to constitute epitomes of the principles of war. Subject to

minor differences in number and in designation, the list most

frequently encountered comprises The Objective, Superiority, The

Offensive, Economy of Force, Movement, Cooperation, Surprise,

Security, and Simplicity.

To rely on a list of this nature, as a condensation of the

fundamentals of war, has been known to cause confusion and to result

in failure to recognize the principles which are intended to be

brought to mind.

For example, misunderstanding has resulted from the designation of the

single word, surprise, as a "principle of war". On the one hand, it

has been denied that surprise embodies a principle, the reason being

advanced that it is neither always necessary, nor feasible, nor even

desirable to attempt to obtain surprise. On the other hand, the

acceptance of the word surprise (see page 73), as itself expressing a

universal truth (which it of course does not except by inference), has

been known to result in the incorrect belief that surprise is always

essential to success. Action based on such a viewpoint is the

equivalent of applying general treatment to specific cases, regardless

of circumstances.

Thus there have resulted distortions of the simple fact that a

relationship exists between the employment of the unexpected, and the

creation of a disadvantage which will hamper an opponent. The correct

formulation of a principle, or of several principles, governing the

employment of surprise, will result in a definite statement that its

appropriate employment is dependent upon the various factors (page 25)

that make up the situation, the influence of each of which requires

evaluation in each separate situation.

Analysis, in like manner, of the so-called "principle of the

objective" as a "principle of war" will show that the objective of a

military force is, in itself, no more a principle of war than the

direction of a physical force is, in itself, a principle of mechanics.

Both concepts, however, involve certain matters of fact which can best

be explained by principles. Such principles take note of the factors

pertaining to the subjects, and indicate the underlying relationships

in a manner to be later shown herein.

Certainly the preceding list (above) of isolated expressions includes

no item which, in the abstract, may not properly be considered as

possibly vital from the strategical and tactical standpoints. But

that these expressions are always vital, and that there are no other

considerations, can scarcely be accepted as final. Even if this

objection could be removed by the inclusion of all factors well known

to be vital, the fact would still remain that these expressions,

standing alone, fail to satisfy the real need; i.e., they fail to

indicate any practical application of the concepts which they are

intended to imply. They do no more than provide a useful point of

origin for further inquiry. When understood on this basis, they

possess a certain value.

* * * * *

The concept underlying the application of principles is correct with

respect to military problems, as well as for all others (page 22).

This purpose, however, cannot be served by a mere collection of nouns

or noun-phrases. Such expressions make no statements of cause and

effect. Their meaning is therefore left to inference and to the

idiosyncrasy of individual interpretation. The formulation, moreover,

of useful principles cannot be satisfactorily established by the

more-or-less random selection of matters, however important,

pertaining to the subject at hand. What is required is a systematic

analysis of the essentials of the subject, with resultant emphasis on

the fundamental causes and effects whose relationships are to be

expressed.

Formulation and Use of Principles. The formulation of a principle,

referred to previously (page 24) as itself a difficult problem,

requires a citation of the factors pertaining to the subject. On the

basis of these factors as causes, the principles, when properly

formulated, also state the effects which may properly be expected.

(See page 22.)

The relationship between causes and effects, or between effects and

their causes, may be expressed in various ways. The requirement is

that the expression be one of fact and that, if the principle purport

to cover the entire subject, all of the pertinent facts (page 24) be

stated, though not necessarily all the details involved.

* * * * *

In addition to the principles of general application (Chapter III),

the later discussion herein includes numerous other principles, with

reference to matters of detail (pages 22-23). To some of these

principles the treatment invites special attention. All principles

included have been phrased with due care, to ensure conformity with

the requirements above stated. The preferred form, herein, for the

usual statement of cause and effect is through the use of phraseology

such as that certain effects "depend on" or are "dependent on" certain

causes, or that certain causes "determine" certain effects, or that

the latter "are determined by" certain causes.

From the standpoint of the exercise of judgment, it is a principle

that the due determination of effects to be produced depends on the

proper consideration of pertinent factors. Once the principles

applicable to any subject have been formulated in necessary detail,

the evaluation of the cited factors with respect to a particular

situation becomes the vital procedure as to any problem where that

subject is involved. In the course of this evaluation, corollary or

subordinate principles may be of assistance (page 22). In military

problems, however, the evaluation usually involves many factors not

susceptible of reasonably exact determination by the use of formulae

(see page 23). In such cases, experience, education, and training

afford the only secure basis for judgment which will produce reliable

conclusions. The principles, therefore, provide reliable guides by

citing the factors to be evaluated in order to arrive at desired

results, but the principles cannot replace logical thought in the

evaluation of the factors.

In formulating principles (see also page 23) as practical guides for

action, as well as in using them when formulated, failure to give

consideration to all pertinent factors may result in vitiating the

effort based on their application. Danger also lies in the fact that

any particular factor will infrequently have the same value--the same

influence on the situation--in any two problems (page 25). Therefore,

in each situation, each factor requires to be weighed in connection

with the others. The soundness of the resulting conclusion will depend

on the extent of the knowledge available (page 2) and on its useful

employment.

Summary of Fundamental Considerations. The factors (page 25) involved

in determining the nature of an effect and of the action to attain it

become fundamental considerations (page 25) when it is desired to

arrive at such a result under a particular set of circumstances.

The relationships obtaining between the desired effect and the action

to attain it, on the one hand, and the factors involved, on the other,

are best expressed in the form of principles. The next chapter is

therefore devoted to the development of basic principles applicable to

military problems.

CHAPTER III

BASIC PRINCIPLES APPLICABLE TO MILITARY PROBLEMS

(The Fundamental Military Principle)

On the basis of the previous discussion as to the natural

mental processes and as to principles useful in their

employment, Chapter III discusses the requirements for the

attainment of an end in human affairs.

The fundamental principle thus derived is then applied to the

needs of the military profession, so as to develop the

Fundamental Military Principle. This Principle indicates the

requirements of a correct military objective and of the action

for its attainment.

Review of Conclusions as to Principles. On the premise that all human

activities and their environment are governed by natural laws (page

22), the preceding chapter has been devoted to an analysis of the

natural mental processes employed in meeting the problems of human

life. This analysis has stressed four fundamental truths:

(1) That a valid rule, or principle, when complete, embraces

all known phenomena pertinent to the relationship

established.

(2) That the logical application of principles to particular

incidents will take account of all the factors of the

principles, and of all known conditions of the incidents.

(3) That such principles afford great assistance in arriving

at sound conclusions, and that the human mind, if without

access to such valid guides, tends to adopt faulty rules

in the effort to serve the same purpose.

(4) That rules of action, however, even though they be valid,

cannot be depended upon to replace the employment of

logical thought.

Procedure for Developing Military Principles. Logically, the next

stage in the treatment of this subject is to develop certain basic

principles applicable, more especially, to the solution of military

problems.

The development of such principles starts, on the basis already

established in this discussion, with a reference to the natural mental

processes used by the normal mature human being before taking

deliberate action (page 19). Under such circumstances, the person who

is to solve the problem has first to establish a basis for his

solution.

To arrive at this basis, which involves an understanding of the

appropriate effect desired, the person concerned requires a grasp of

the salient features of the situation, a recognition of the incentive,

and an appreciation of the effect which he has been directed to

produce or has adopted on his own initiative. To complete the basis

for his solution, he also requires an understanding of comparative

resources as influenced by the conditions obtaining at the time.

During the actual solution of the problem, the person concerned takes

cognizance first, of the existing situation, picturing it in his mind.

Then, unless satisfied that he desires no change, he creates for

himself mental images of future situations. The pictured condition

decided upon after consideration of the pertinent factors involved, be

it the situation to be maintained or a new situation to be created,

constitutes an effect he may produce for the further attainment of the

appropriate effect desired, already established as an essential part

of the basis of his problem. (See page 25.)

With the existing situation and a new situation now clear, what action

is he to take to change the one into the other? Or, if no change is

desired, what action is he to take to maintain the existing situation?

What acts or series of acts should he decide upon, plan in detail,

inaugurate, and supervise (page 3), to attain the effect which he has

envisaged for the further attainment of the appropriate effect

desired?

The correct solution of problems therefore hinges on the requirements

involved in the effects to be produced and in the action to produce

them. If these requirements are ascertained, a principle can be

formulated as a valid guide for the solution of human problems.

Requirements for the Attainment of an End. The discussion to this

point has established the fact that an end in view, a result to be

produced, an effect desired, is very closely connected with a further

effect which the attainment of the former is intended to produce.

Human motives spring from deep-seated incentives often derived from

distant sources, so that, even when the person concerned is acting

wholly on his own initiative, he will rarely, if ever, be uninfluenced

by some further effect desired, inherent in his situation (see page

19).

An end in view, therefore, from the viewpoint of the person who is

endeavoring to visualize its accomplishment as a method for attainment

of a further aim, will necessarily achieve such further aim, or at

least contribute to its achievement. The first requirement,

accordingly, of such an end in view is that it be suitable to any

further aim, whatever that aim may be. It may be said, therefore, that

a correct end in view satisfies the requirement of suitability as to

the appropriate effect desired, whatever this further effect may be.

Important as suitability is, however, a reasonably responsible person

will recognize that this consideration, alone, does not satisfy all

requirements. An end in view remains a mere desire, without

possibility of attainment, unless such a result is practicable of

accomplishment. A correct end in view, therefore, satisfies also the

requirements of feasibility.

Consideration of feasibility calls for a survey of comparative

resources (page 30). Such a survey will cover the extent of the

resources (means available) of those making the effort, as compared to

the resources (means opposed) of those who may oppose it. Full account

is also to be taken, as to feasibility, of the natural and artificial

conditions which the effort will encounter before it can produce the

contemplated result. The responsible person will ask himself where the

effort is most likely to be successful, and what obstacles, in

addition to those represented by opponents, he will be required to

surmount. The effects of such conditions may alter the ratio otherwise

presented by comparative resources.

Consideration of the characteristics of the field of action may thus

disclose features which will greatly influence the possibility of

accomplishment, as well as the character of the effort to be made,

from the standpoint of feasibility. The second requirement, therefore,

is that of feasibility with respect to comparative resources, i.e.,

the means available and opposed, as influenced by the physical

conditions prevailing in the field of action.

Although believed to be both suitable and feasible, the requirements

for the attainment of an end are not yet completely established. There

is still required a reckoning of a profit-and-loss account of the

whole undertaking, to estimate whether it will be advantageous. What

will be the cost, and what will be the gain? Is the effort worth

while? Or should one be content with venturing less and gaining less?

What is the bearing on possible future action? The consequences as to

costs, always important considerations in dealing with human problems,

are frequently the paramount determinant. The third requirement,

therefore, is acceptability with respect to the consequences as to

costs.

These requirements invite attention to the factors, already

discussed, whose influence (see page 25 as to factors) determines the

character of the effort required to attain an end.

The Fundamental Principle for the Attainment of an End. Here, then,

are the broad fundamental considerations which affect the solution of

every human problem. In a narrower field, the considerations may fall

within more specific limits, but a principle sufficiently broad to be

applicable to all cases appears to comprehend those inclusive factors

mentioned in the preceding paragraphs.

A review of these paragraphs will disclose that the factors pertaining

to the several requirements may be so grouped as to constitute a

single fundamental principle governing the attainment of an end in

human affairs,--as follows:

In any human activity, the attainment of a correct end in view depends

on fulfillment of the requirements of

Suitability of the end in view, as determined by the factor

of the appropriate effect desired,

Feasibility of the effort required, on the basis of

comparative resources, as determined by the means

available and opposed, influenced by the factor of the

physical conditions prevailing in the field of action, and

Acceptability of the results of the effort involved, as

determined by the factor of the consequences as to costs,

which factors are in turn dependent on each other.

The Interdependency of the Factors. As previously observed (page 28),

the factors cited in the foregoing principle are themselves

interdependent. This fact results from working of natural law (page

22), for it is a recognized phenomenon that every effect is the result

of certain causes, and that every effect is itself, in turn, the cause

of further effects (page 19).

Accordingly, when the evaluation of any factor is under consideration,

its value as an unknown quantity can be determined to the extent that

the values of the other pertinent factors are known. (See page 23, as

to the discussion of the quantities in an equation.) The significance

of each, in any situation, is therefore determined by the influence of

the other factors. The relationships existing among them can best be

expressed in the terms of four corollary principles (page 27), next to

be discussed.

* * * * *

For example, questions frequently arise as to what is the appropriate

effect to be desired in a particular situation. Whether a desired

effect is feasible of attainment, and whether certain consequences,

though undesirable, will be acceptable, in view of the gains, can be

determined by evaluation of the means available and opposed,

influenced by the physical conditions prevailing in the field of

action, and of the consequences as to costs. If a desired effect is

thereby found to be not feasible of attainment, or to be unacceptable

as to consequences, deferment of such effort is indicated. A proper

solution in such case would adopt some lesser effect, in conformity

with the further aim, feasible of accomplishment, and acceptable as to

its consequences.

If (with respect to the further aim, mentioned above) the person

concerned is acting under the instructions of another, there will

frequently be injected into the equation, in addition to the factors

already noted, a further effect desired, indicated by higher

authority. Such an indication will often operate to narrow the limits

of the problem. This is true even if the person concerned is acting

wholly on his own initiative and responsibility (pages 29-30).

These considerations lead to the formulation of what may be called the

corollary principle for determination of the appropriate effect to be

desired in human affairs,--as follows:

In any human activity, the appropriate effect to be desired

(i.e., an end in view, a result to be accomplished) depends on

fulfillment of the requirements of

Suitability of the end in view, as determined by the factor of

the further effect desired (if such further effect is

indicated),

Feasibility of the effort to attain the end in view, on the

basis of comparative resources, as determined by the

factors of the means available and opposed, influenced by

the factor of the physical conditions prevailing in the

field of action, and

Acceptability of the results of the effort involved, as

determined by the factor of the consequences as to costs.

* * * * *

If, to take a further example, the known factors include the

appropriate effect desired, the means opposed, the physical conditions

prevailing in the field of action, and the consequences as to costs,

the only unknown remains the means available. The question then is,

what means need be made available for the accomplishment of the

contemplated effort? The answer to this question may be found in the

application of what may be called the principle for the determination

of the proper means to be made available in human affairs,--as

follows:

In any human activity, the proper means to be made available

depend on fulfillment of the requirements of

Suitability of the means (in kind and amount) to accomplish

the end in view, as determined by the factor of the

appropriate effect desired,

Feasibility of the effort to make such means available on the

basis of comparative resources as determined by the factor

of the means opposed, influenced by the factor of the

physical conditions prevailing in the field of action, and

Acceptability of the results of the effort involved, as

determined by the factor of the consequences as to costs.

* * * * *

The influence of physical conditions in the field of action may be

illustrated by any case where ends otherwise feasible of attainment

cannot be achieved without effecting changes in such conditions. The

resolution of the uncertainty then requires study to determine what

suitable changes can be made. Changes for such a purpose may take

various forms, such as the construction of physical features in the

area involved, or the destruction of such features already existing;

or, again, both methods may be employed. Examples of such changes have

existed and still exist in profusion, some of them, military and

non-military, being on such a scale as radically to alter the previous

status with respect to entire nations. The question as to what changes

ought to be effected in the prevailing physical conditions, in order

to attain a certain objective, can be answered by the application of

what may be called the principle for the determination of the proper

physical conditions to be established in the field of action,--as

follows:

In any human activity, the proper physical conditions to be

established in the field of action depend on fulfillment of the

requirements of

Suitability of such conditions to the end in view, as

determined by the factor of the appropriate effect

desired,

Feasibility of effort to establish such conditions, on the

basis of comparative resources, as determined by the

factors of the means available and opposed, influenced by

the factor of the physical conditions existing in the

field of action, and

Acceptability of the results of the effort involved, as

determined by the factor of the consequences as to costs.

* * * * *

The factor of consequences as to costs also calls for special notice.

The influence of this factor frequently justifies abandonment of

suitable ends in view, even though their attainment has been

determined to be feasible, because the loss involved would out-weigh

the gain. Immediate success may be attained at such cost as to prevent

the attainment of larger ends (see the discussion, pages 9 and 10, of

the relationship of strategy and tactics).

On the other hand, the circumstances of the case may well justify

loss, however great, because the alternative is unacceptable, even

though the consequences involve complete destruction. Moreover, the

need for swift and aggressive action in many activities (notably in

war), for resolute prosecution of the plan, for timely seizure of

opportunity, and for acceptance of justified risks, requires that

consideration of consequences as to costs never be emphasized beyond

its proper weight. To determine such proper weight calls, frequently,

for judgment of the highest order, and is, in the military profession,

a direct responsibility of command. This responsibility can be

discharged by the application of what may be called the corollary

principle for the determination of acceptable consequences as to

costs,--as follows:

In any human activity, the acceptable consequences as to costs

depend on fulfillment of the requirements of

Suitability of the end in view, as determined by the factor

of the appropriate effect desired, and

Feasibility of the effort to attain the end in view, on the

basis of comparative resources, as determined by the

factors of the means available and opposed, influenced by

the factor of the physical conditions prevailing in the

field of action.

Special Nature of War as a Human Activity. A principle found, by

careful analysis, to be governing as to human activities of any

nature, is also applicable to the problems of war. This is true

because war is a human activity, differing from other human activities

only in the specialized character of the factors that enter.

The effect desired in war has a character distinctly military and,

ultimately, through the reestablishment of a favorable peace, a

political character (see pages 7-9).

The means available (or opposed) in war are the human and material

components of fighting strength (page 8). The physical conditions

prevailing in the field of action are, in war, the characteristics of

the theater of operations. Fighting strength is thus derived from the

means available (or opposed) in war, as influenced by the

characteristics of the theater. Relative fighting strength

(comparative resources in war) involves a comparison of means

available with means opposed, due account being taken of the influence

exerted on both by the characteristics of the theater. In war,

relatively large masses of human beings oppose each other with hostile

intent, while the means available and opposed, and the physical

conditions established by the operations of war in the theater of

action, tend more and more to acquire a highly specialized character.

The consequences as to costs, in war, also assume a special

significance, inasmuch as they may materially influence the

development of entire nations or of the world situation.

Factors as Universal Determinants in War. Tabulated for convenient

reference and expressed in terms in general use in the military

profession, the factors governing the attainment of an end in war are

therefore:

(a) The Nature of the appropriate Effect Desired,

(b) The Means Available and Opposed,

(c) The Characteristics of the Theater of Operations,

and

(d) The Consequences as to Costs.

These factors, thus expressed in abstract form, are the universal

determinants of the nature of the objective and of the character of

the action to attain it. Their further resolution into factors of more

concrete form is indicated hereinafter (see Chapter VI, in the

discussion of Section II of the Estimate Form).

The Objective in War. The objective (page 3), a term long in use in

the military profession in connection with the "objective point", has

acquired by extension the significance of something more than the

physical object of action. The latter, as explained later (page 37),

is properly denominated the "physical objective".

In the abstract, an "objective", in present general usage as well as

in the military vocabulary, is an end toward which action is being

directed, or is to be directed; in brief, an end in view, a result to

be attained, an effect desired (pages 19 and 30). An objective is an

effect to be produced for the attainment of a further objective,

itself a further effect. As already demonstrated (page 30 and

following), the attainment of an end, in any human activity, requires

action to maintain the existing situation or to create a new one.

Therefore, in war, a special form of human activity, the attainment of

an objective requires that action be actual imposition of an outside

agency. The attainment of a correct military objective (discussed in

detail in Chapter IV) requires, accordingly, the creation or

maintenance of a favorable military situation.

An objective, in the sense of an end in view, a result to be

accomplished, is manifestly an objective in mind. As already indicated

(page 36), however, military usage also assigns to the term

"objective" an additional meaning, a meaning exclusively concrete.

Results in war are attained through the actual or threatened use of

physical force (pages 8 and 9) directed with relation to something

tangible, such as, for example, some physical element of the enemy's

strength.

Action as to this tangible feature (e.g., if it is destroyed,

occupied, neutralized, or otherwise dealt with) will result in, or

further the attainment of, an effect desired. Thus the physical

objective occupies a sharply defined position in warfare, in that it

establishes the physical basis of the objective and indicates the

geographical direction of the effort. Since the physical objective is

always an object--be it only a geographical point--, it is more than a

mental concept; it is an objective in space.

For example, the objective being "the destruction of the enemy

battleship", the physical objective is the enemy battleship.

As used herein the expression "the objective" or "the military

objective" (page 55), when unqualified, ordinarily indicates the

mental objective. The term is properly applicable to a physical

objective when the context makes the meaning clear. Ordinarily, and

always when clarity demands, a tangible focus of effort is herein

denoted a "physical objective".

Military Operations. Appropriate action to create or maintain a

situation will take the form of a military operation. An operation, in

the basic sense, is merely an act, or a series of acts. The word is

derived from the Latin opus, meaning "work". A military operation is

therefore an act, or a series of included acts (i.e., work), of a

military character. A military operation may consist of an entire

campaign, or even of several such, constituting a clearly defined

major stage in a war; or such an operation may consist of portions

thereof. The term is also applied, properly, to entire series of acts

on the part of successive commands, from the higher to the lower

echelons, to and including distinctive military actions which relate

to the merest routine.

A plan of action to attain a military objective is, therefore, a plan

of military operations, including supporting measures (see page 167),

considered or adopted as a method of procedure for the achievement of

that end (see page 21). Such a plan or method of procedure requires

action with relation to correct physical objectives in such a manner

as to attain the objective, i.e., to maintain the existing situation

or to create a new one, conformably to the appropriate effect desired.

A plan of military operations may be regarded as reasonably effective

if the direction or geographical trend of the effort provides for

proper action with relation to the correct physical objectives; if the

force concerned utilizes positions advantageous in relation to those

of the opponent; if the fighting strength is so apportioned as to

provide for requisite power at points likely to be decisive, without

undue weakening at other points; and if future actions, in seeking the

effect desired, will be unhampered by obstacles with which the force

cannot cope. These essentials apply to all of the various combinations

of circumstances, i.e., situations (page 20), which may materialize as

action progresses and the original situation unfolds.

A properly conceived plan of military operations therefore makes

provision, necessarily, for certain salient features of such

operations, as follows:

The physical objectives involved,

The relative positions utilized,

The apportionment of fighting strength, and

The provisions for freedom of action.

As will later be observed (Chapters VII and VIII), the content of

plans for naval operations may be classified under the headings listed

above. In such plans the salient features noted will be observed,

also, to occur, subject to certain exceptions, in the sequence above

indicated. Similar observations are applicable as to plans

systematically prepared for direction of forces operating on land and

in the air.

A military operation which is progressing favorably, whatever the

medium of action, may therefore be justifiably stated to include

provision for the following salient features:

Effective action with relation to correct physical

objectives,

Projection of military action from advantageous relative

positions,

Proper apportionment of fighting strength, and

Ensurance of adequate freedom of action.

Since, at any moment of its successful prosecution, a military

operation presents, inherently (page 38), a favorable military

situation, the salient features of such an operation constitute, also,

the salient features of a favorable military situation. Manifestly,

any deficiencies in these respects will indicate that in certain

particulars the situation is not entirely favorable, if not actually

unfavorable.

Determination of the Salient Features. Because the form which a

military operation takes, in the effort to attain a military

objective, depends upon the factors which are the universal

determinants (page 36) of the character of the effort, the salient

features of such an operation are determined by the same factors. A

valid guide as to determination of the salient features of a favorably

progressing military operation, seen (above) to be identical with

those of a favorable military situation, may therefore be formulated

as a principle for determining these salient features, as follows:

The determination of

} { Suitability, as determined by

} { the factor of the appropriate

Correct physical objectives, } { effect desired.

} {

Advantageous relative } { Feasibility, by reason of

positions, } { relative fighting strength,

} depends { as determined by the factors

Proper apportionment of } on { of the means available and

fighting strength, and } their { opposed, influenced by the

} { factor of the characteristics

Provision for adequate } { of the theater of operations,

freedom of action } { and

} {

} { Acceptability, as determined

} { by the factor of the

} { consequences as to costs.

Since the particular character of each salient feature of a situation,

or of an operation, is determined by the influence, exerted by the

identical factors (as noted), there is a resulting interdependency,

important though indirect, among the several features. This

interdependency is explained hereafter. (Chapter IV).

The Fundamental Military Principle. The Fundamental Principle for the

Attainment of an End in human affairs (page 32) has invited

attention to the factors, pertinent to suitability, feasibility, and

acceptability, seen to be applicable, as well, to any military effort

(page 35). As also noted, a military effort will necessarily consist

of military operations, whose salient features depend upon the same

factors. The factors, in turn, have been observed (page 32 and

following) to be interdependent.

[Illustration: THE FUNDAMENTAL MILITARY PRINCIPLE (diagram)]

These considerations lead to the formulation of a derivative of the

Fundamental Principle for the Attainment of an End in human affairs,

in the form of

The Fundamental Military Principle

The attainment of a military objective (the creation or maintenance of

a favorable military situation) depends on effective operations

involving the salient features of

Effective action with relation to correct physical

objectives,

Projection of action from advantageous relative positions,

Proper apportionment of fighting strength, and

Ensurance of adequate freedom of action,

each fulfilling the requirements of

Suitability, as determined by the factor of the appropriate

effect desired,

Feasibility, by reason of relative fighting strength as

determined by the factors of the means available and

opposed, influenced by the factor of the characteristics

of the theater of operations, and

Acceptability, as determined by the factor of the consequences

as to costs,

which factors are in turn dependent on each other.

* * * * *

The Fundamental Military Principle, as a valid guide, encounters no

exception in the field it purports to cover. As a practical guide, it

brings to attention, in broad outline, all the causes and effects

which are involved. The principle affords a proper basis for the

formulation of corollary principles for the determination, in any

particular situation, of any element noted therein whose value may be

unknown but may be ascertained by reference to other pertinent

elements which constitute known quantities. (See pages 21-27.)

As later explained (Chapter IV), the two major applications of the

Principle relate to the selection of a correct military objective and

to the determination of effective military operations to attain an

objective (see page 28).

A corollary Principle of the Correct Military Objective will

accordingly state that the selection of a correct military objective

depends on the due consideration of the salient features and the

factors cited in the Fundamental Military Principle. The application

of this corollary is discussed in Section II of Chapter IV.

A corollary Principle of Effective Military Operations will similarly

state that the determination of effective operations for the

attainment of a military objective depends on the due consideration of

the salient features and the factors cited in the Fundamental Military

Principle. The application of this corollary is explained in Section

III of Chapter IV.

These principles can be used as a basis for formulating the plans of

the commander concerned, and, accordingly, for determining his own

action. They can also be used as a basis for rendering sound opinions,

when requested of the commander, as to plans and actions contemplated

by higher authority. The principles are in like manner applicable for

purposes of historical study involving analysis of operations of the

past.

CHAPTER IV

THE APPLICATION OF THE FUNDAMENTAL MILITARY PRINCIPLE

(Objectives--Their Selection and Attainment)

Section I of Chapter IV discusses the major components of all

military problems.

Section II deals with the fundamental considerations having to

do, generally, with the first of these components, i.e., the

selection of correct military objectives; the application,

more specifically, is reserved for Chapter VI.

Section III deals with the fundamental considerations having

to do, generally, with the second of the two major components,

i.e., the determination of effective military operations for

the attainment of such objectives; the application, more

specifically, is reserved for Chapter VII.

The selection of objectives has a secondary application, also,

to the discussion in Chapter VII, while the determination of

operations has a similar application to that in Chapter VI.

Both subjects, i.e., as to objectives and as to operations,

have application also to Chapter IX.

The chart on page ii shows these relationships.

I. MAJOR COMPONENTS OF MILITARY PROBLEMS.

In the two preceding chapters, the study of the natural mental

processes has brought to notice that, to meet the requirements of

suitability, feasibility, and acceptability as to consequences in the

proper solution of a military problem, it is first necessary to

establish a sound basis for that solution. Such a basis involves an

understanding of the appropriate effect desired and of relative

fighting strength (see pages 29 and 30).

In each situation an understanding of the appropriate effect desired,

from the standpoint of suitability, requires:

(1) A grasp of the salient features of the situation,

favorable and unfavorable, including the perplexity inherent

therein,

(2) A recognition of the incentive to solution of the

problem, i.e., a realization of the desire or need for

attaining a certain effect, an objective (page 36) which will

be the maintenance or creation of a favorable military

situation, and

(3) An appreciation of this objective in its relationship

to the next further result to be accomplished by its

attainment.

An understanding of relative fighting strength involves consideration

of the means available and opposed, as influenced by the

characteristics of the theater of operations. With this understanding

there is provided a sound basis for the determination, later, of the

feasibility of courses of action and of their acceptability with

respect to consequences as to costs.

In the premises, the ability to understand the nature of a military

problem is dependent on the knowledge, experience, character, and

professional judgment of the commander. These qualities enable him to

grasp the significance of the salient features of the situation. The

same personal characteristics are instrumental in the recognition of

the incentive. Analysis indicates that an incentive may arise (1) by

reason of a directive issued by higher authority, or (2) from the fact

that a decision already reached by the commander has introduced

further problems, or (3) because of the demands of the situation.

However, the primary consideration in understanding the nature of the

problem is the appreciation of the objective from which the problem

originates, i.e., the just estimation or accurate evaluation of this

objective. Such consideration is primary because appreciation of this

objective involves, as necessary concomitants, a grasp of the salient

features of the existing situation (to be maintained or changed) and a

recognition of the incentive.

Correct appreciation of this objective, in its relationship to the

further effect to be produced, is thus the principal consideration in

reaching an understanding of the appropriate effect desired. It is, to

repeat, through an understanding of this factor and of the factors of

relative fighting strength that the commander establishes the basis

for the solution of his problem. (See Section I of Chapter VI, page

118).

The Solution of a Military Problem. When the commander has thus

obtained an understanding of the basis of his problem, the actual

procedure of solution is undertaken through the consideration of the

factors involved in their influence on the various plans for the

attainment of the appropriate effect desired, as thus established. The

best plan, selected and embodied in outline in the decision, can then

be further developed, if necessary, into a general plan for the

commander's force and, finally, into a detailed plan, as the solution

of the problem. (See page 22.)

The Major Components of a Military Problem. Each plan considered by

the commander will involve (page 21) two major considerations:

namely--an effect to be produced and the action required to produce

it; or, in military terms, a correct military objective (or

objectives) and effective operations for its attainment. The selection

of correct military objectives and the determination of effective

operations for their attainment are therefore the two major components

of a military problem, because they are the principal considerations

on which depends the soundness of military decision. To meet these

requirements is a prime function of command, one which demands

professional judgment of the highest order.

The major components of a military problem are of course intimately

connected, because a purposeful action, accomplished, is equivalent to

an objective, attained. Furthermore, the attainment of an objective

involves the accomplishment of effective operations.

Because of the importance of the subject, the relationship between

these two major components deserves very careful analysis. As has been

observed (page 30), the action to be taken depends, in the first

instance, on the effect to be produced. Therefore, the objective is,

as compared to the action to attain it, the paramount matter.

Moreover, there is necessarily included, in the procedure of selecting

a correct objective, a consideration as to whether the action to that

end will be feasible and as to whether the consequences involved will

be acceptable on the basis of the costs which will be exacted. If,

then, the objective has been correctly selected in any situation, this

procedure will have included, as a necessary incidental, the

determination also, in the proper detail, of the operations required

for its attainment.

Of the two major components involved in the selection of the best

plan, the primary relates, therefore, to correct objectives.

Accordingly, this consideration is most aptly expressed in terms of

the "selection" of objectives. The "determination" of necessary

operations is a proper expression of the procedure therein involved,

because this procedure, though also involving a major component of the

problem is dependent on the primary consideration of objectives.

A valid guide for practical use during the process of solving military

problems will therefore provide a basis, primarily, for the selection

of correct objectives. However, the procedure for such selection,

though requiring consideration of the action involved in attaining

objectives, will seldom call for a complete analysis of such

operations. Therefore, it is also desirable, for the solution of

military problems, to provide a valid guide for the determination of

effective operations, in detail. This guide may be used on occasions

when, the correct objective having been selected, the only remaining

problem is to work out the detailed operations involved.

The Fundamental Military Principle, developed in the preceding

chapter, has been formulated to fulfill the requirements described in

the preceding paragraph. Through the exhaustive analysis of the

elements involved, there has been provided, in the form of a single

fundamental principle, a valid guide for the selection of correct

military objectives and for the due determination of effective

operations for their attainment.

In the present chapter, the abstract application of the Principle is

discussed in terms of fundamental considerations. Section II of the

chapter deals with the selection of objectives; this subject, in more

specific terms, is later expanded in Chapter VI. Section III of the

present chapter deals with the determination of operations; this

subject, in more specific terms, is expanded in Chapter VII. The

present chapter affords a treatment applicable to military problems of

any nature. Later expansion is applicable, more especially, to naval

problems.

This arrangement of the subject matter has been adopted for two

reasons. First, discussion of fundamental considerations, thus taken

up at the present point, immediately follows the formulation of the

principle (in Chapter III). Furthermore, a fundamental treatment,

prior to Chapters VI and VII, permits maximum brevity in the

discussion, therein. The commander, having mastered the fundamentals

dealt with here, can later follow the detailed procedure with minimum

distraction due to reference to the preceding discussion.

Essential Elements Involved. As previously stated, the problems of war

differ from those of other human activities with respect, only (page

35), to the specialized character of the factors that enter.

The final outcome is dependent (page 8) on ability to isolate, occupy,

or otherwise control the territory of the enemy. The sea, though it

supplements the resources of land areas, is destitute of many

essential requirements of man, and affords no basis, alone, for the

secure development of human activities. Land is the natural habitat of

man. The sea provides routes of communication between land areas. The

air affords routes of communication over both land and sea.

These facts inject into military operations certain factors peculiar

to movement of military forces by land, sea, and air (page 60). There

are also involved the specialized demands of a technique for the

imposition of and the resistance to physical violence. In addition

there appear those factors related to the psychology of human

reactions to armed conflict.

In any situation involving opposing armed forces, the problem, as in

any human activity (page 30), is, from the standpoint of each

opponent, a matter of maintaining existing conditions or of bringing

about a change. The method employed, if the action is to be effective,

will follow lines calculated to shape the ensuing progressive changes

in circumstances toward the attainment of the end in view. The action

to be taken will be ineffective if it does not support the calculated

line of endeavor, i.e., if it is not suitable or adequate forcibly to

shape the course of events either toward the creation of a desired new

and more favorable situation, or the maintenance of the original

conditions.

The analysis of the principal components of a military problem--i.e.,

the military objectives and the military operations appropriate to the

effort for their attainment--therefore requires a study of such

objectives and operations in terms, respectively, of a favorable

military situation (page 37) and of a favorably progressing military

operation (page 38). As has been observed, the salient features of

such a situation or operation are, from the abstract viewpoint,

identical, as are also the factors which determine the character of

such features (page 39). As a covering word for such features and

factors, alike, the term "elements" appears especially suitable,

inasmuch as it properly comprises the constituent parts of any

subject, as well as the factors which may pertain thereto.

Accordingly, the analysis, following, of the procedure for selection

of correct military objectives is made in terms of the essential

elements of a favorable military situation. For like reasons, the

analysis of the procedure for determining the character of the

detailed operations required is made in terms of the essential

elements of a favorably progressing military operation. (For these

elements, see the salient features and the factors cited in the

Fundamental Military Principle, page 41.)

II. SELECTION OF CORRECT MILITARY OBJECTIVES

Nature of Military Objectives. In the previous discussion (page 36),

the military objective has been defined as the end toward which action

is being, or is to be, directed. As such it has been noted as an

objective in mind. The tangible focus of effort, the physical

objective toward which the action is directed, has been observed to be

an objective in space. The physical objective is always an object, be

it only a geographical point, while the objective, being a mental

concept, is a situation to be created or maintained.

The term "objective" requires circumspection, not only in the manner

of its expression (see page 53), but in its use. The latter is true

because the purport of the objective under consideration will vary

with the viewpoint of the echelon concerned. For instance, the proper

visualization of an objective, as an "effect desired" (page 19), calls

for a correct answer to the question, "Who desires this effect to be

produced?" (See page 4).

A variety of viewpoints is thus a natural characteristic of the chain

of command (pages 11-13), whose functioning creates what may be called

a "chain of objectives".

Necessary exceptions aside, the commander expects to receive, from his

immediate superior, an assigned objective, which that superior thus

enjoins the commander to attain. The commander, in turn, through the

use of the natural mental processes already explained, decides on an

objective, for the general effort of his own force, to attain the

objective assigned by his immediate superior.

As a subordinate, a commander to whom an objective has been assigned

is responsible to his immediate superior for its attainment. The

commander may, however, also occupy the position of an immediate

superior to one or more commanders on the next lower echelon. In such

capacity, he may assign objectives to these immediate subordinates. By

attaining such an assigned objective, each of these subordinates thus

contributes to the success of the complete effort planned by his

immediate superior, to the extent represented by his own assigned

share of the effort.

A commander can scarcely expect to receive in full the intelligent

support of his subordinate commanders, unless he makes clear to them

the character of his own planned effort. It is customary, therefore,

when assigning an objective to a subordinate, also to inform him of

the purpose which its attainment is intended to further. Stated

differently, a commander, when imposing upon an immediate subordinate

an effect which he is to produce, informs him, at the same time, of

the nature of the military result which he, the immediate superior,

has determined to bring about.

This is the part of wisdom, not merely of choice. It acquaints the

immediate subordinate with the objective of the immediate superior and

thus enables the former to comprehend wherein the attainment of his

own assigned objective is expected to contribute to the attainment of

the effect desired by his superior.

Since the attainment of the assigned objectives will represent the

consummation of the general plan of the immediate superior, the

purpose of each of these assignments is to assist in the attainment of

the objective announced, for his entire force, by the immediate

superior (see also page 12).

From the viewpoint of the subordinate, the objective thus assigned by

the immediate superior becomes the appropriate effect desired,

essential to the determination of the accomplishment which the former

is to effect by his own effort. On occasion, also, the full scope of

the appropriate effect desired may require consideration of the

objectives of higher echelons in the chain of command, so far as such

objectives may be known or deduced.

The responsibility of the immediate superior, in the matter of

ensuring that his immediate subordinates understand the purpose of

their assigned objectives, is in no respect less than that which falls

upon these subordinates in the execution of their own assignments. By

failing to provide subordinate commanders, through whatever methods,

with a knowledge not only of the details of his plan but of the

general objective which their integrated effort is calculated to

attain, the superior may actually subject his undertaking to the risk

of failure.

The decision as to the general plan (page 44) for the attainment of

his assigned objective provides the commander with an objective which

he himself has originated. With the plan for the attainment of his

general objective clearly fixed in mind, the commander may now proceed

to the selection of one or more objectives of a specific nature, the

integrated attainment of which will ensure the attainment of his

assigned objective. The instructions which he may then give,

severally, to his immediate subordinates in a detailed plan of

operations, thus indicate to the latter their assigned objectives.

(See also page 22.)

The source of the incentive (page 44) has an intimate connection with

the assigned objective. Furthermore, whatever the origin of the

incentive, the ability to select correct objectives is an essential

element in the mental equipment of the commander.

For example, if the incentive arises by reason of a directive received

from higher authority, such directive will presumably assign an

objective, specific or inferred. The commander to whom such an

objective is assigned is responsible for a correct understanding of

all the implications involved, including the relationship between the

assigned objective and the general objective of the next higher

commander, which represents the purpose of the assigned objective. On

occasion it will also be necessary for the commander to consider the

relationships involved with the further objectives of the higher

command (page 49). Again, without any suggestion of cavilling at

orders received, the commander may also find occasion to examine, with

care, the implications of his assigned objective, because of his

responsibility for taking correct action in the premises (page 15).

If the incentive arises from a decision previously made by the

commander, it follows that such decision will have embodied an

objective, selected by the commander himself.

If the incentive arises because of the demands of the situation, the

commander is responsible for recognition of the necessity for action

and for the correct selection of an appropriate objective, to be

adopted by him as a basis for his own action as if it were assigned by

higher authority.

An assigned objective having been established with respect to the

basis for his problem, the commander is always responsible for the

correct selection of an objective to serve as the end in view for the

general, integrated action of his subordinate commanders.

Once such an objective has been selected, the commander is further

responsible for selecting, on the basis provided thereby, correct

objectives to be assigned to his subordinate commanders.

For various practical reasons, therefore, the responsibility of the

commander requires of him the ability to select correct objectives. On

the basis of classification with respect to the authority making the

selection, analysis will demonstrate the existence of two types of

objectives.

These two types of objectives are (see page 30 as to effects and

further effects), namely, (1) the assigned objective (page 48)

ordinarily indicated by higher authority, exceptionally determined by

the commander for himself, and (2) the objective typically selected by

the commander, himself, as the end in view for the integrated effort

of his subordinates. It will be noted that in the latter category

there will fall, not only the general objective referred to

immediately above, but numerous other objectives for whose attainment

provision may be needed during the actual prosecution of the effort or

in anticipation thereof.

Procedure for Selection of Correct Military Objectives. The

Fundamental Military Principle (page 41), properly applied, is the

basis for the selection of any or all of such objectives. The

procedure involves the direct application of the corollary Principle

of the Correct Military Objective.

According to this principle, the selection of a correct military

objective depends on due consideration of the salient features noted,

i.e., correct physical objectives, advantageous relative positions,

proper apportionment of fighting strength, and provision for adequate

freedom of action. These features, discussed in greater detail

hereafter (in this chapter), are determined by factors cited in the

Principle (pages 41-42).

The first factor being the appropriate effect desired, a correct

military objective is selected, in the first instance, by reference to

the requirement of suitability as to this factor. This appropriate

effect desired may be indicated by the higher command (page 44), or

may be determined by the commander himself as hereinafter explained

(page 52).

When the appropriate effect desired has been established, the next

consideration is, "What physical objective (or objectives) can be

found, action with relation to which will, if successful, attain this

effect?"

For example, if the appropriate effect desired were the "reduction of

enemy battleship strength" in a certain area, then an enemy battleship

appearing therein would manifestly be a correct physical objective. A

suitable action with relation thereto would be "to destroy the enemy

battleship", in which case the objective involved in the action would

be "the destruction of the enemy battleship".

Any lesser accomplishment, such as infliction of damage on the enemy

battleship, or its repulse, or its diversion elsewhere, would also be

suitable to the appropriate effect desired, though not in the same

degree. Each such visualized accomplishment, suitable to the

appropriate effect desired, may properly be considered as a

tentatively selected objective.

An objective having been tentatively selected on the basis of the

appropriate effect desired, its final selection will naturally depend,

as indicated in the Principle, on the feasibility of the effort

involved in the attainment of each such objective, and on the

acceptability of the consequences as to costs.

In investigating such feasibility, account is taken of the relative

fighting strength. With relation to the enemy battleship, for example

(see above), the commander would consider the means available to him

and the means opposed (including the enemy battleship and any

supporting forces), as influenced by the characteristics of the

theater.

This investigation will include, necessarily, a sufficient analysis of

the salient features of the operation required to attain each

objective. Such features include the nature of the physical objectives

(the battleship and any other forces, for instance), the possibilities

of relative position, the problems involved in apportioning the forces

on either side, and the proper considerations as to freedom of action.

A similar study with respect to the acceptability of the consequences

to be expected, as to the costs involved in the operation, will

provide a basis for a conclusion as to that factor.

If the attainment of an objective is found to be infeasible, or

feasible only at the expense of unacceptable consequences, the

proposed objective will naturally be rejected, and some other

objective will be considered (page 33).

The objective finally adopted as the best will be that which, all

things considered, is best adapted to the requirements of suitability,

feasibility, and acceptability, as outlined in the Fundamental

Military Principle.

The Appropriate Effect Desired, as the Basis for the Objective. As

will be appreciated from the foregoing discussion, the first factor in

the selection of a correct objective is the "appropriate effect

desired". The evaluation of this factor is not always easy, for

reasons which will be explained.

The procedure (as indicated by the Principle of the Appropriate Effect

to be Desired--page 33) is the same as for the selection of an

objective. This identity of procedure is natural, because the

appropriate effect desired, used as a basis for selecting the

commander's general objective, itself involves the appreciation of an

objective. The latter is, in fact, one of the "chain of objectives"

previously mentioned (page 48).

Under conventional conditions this objective is selected by higher

authority, and is assigned to the commander in his instructions from

the next higher echelon (page 48). The objective so indicated will of

course, under sound procedure, have been selected by higher authority

on the basis embodied in the Fundamental Military Principle.

When an established chain of command (page 11) is in effective

operation, the path to the appropriate effect desired will therefore

normally be indicated through an assigned objective, by the immediate

superior. This assignment, however, or the failure to receive such an

indication, does not relieve the commander from the responsibility for

taking correct action on his own initiative. Such necessity may arise

should he find, in the exercise of a sound discretion, that his

instructions need modification or alteration, or even that it is

necessary for him to depart from his instructions under circumstances

of great emergency (page 15-16).

Furthermore, the objective may be adopted by (rather than assigned to)

the commander concerned, on his own initiative, in order to meet the

demands of a situation (page 50) as to which the higher command has

not yet had time or opportunity to act.

Moreover, even when an objective is assigned by higher authority in

the usual course, it may be expressed in such terms as to require

examination in order to enable the commander to appreciate it (page

43), as to its bearing on his operations. In fact, studious analysis

may be necessary for this purpose.

For example, if the objective so indicated does not specify a

clearly-defined goal, the commander will need to make a thorough study

in order to appreciate the full implications intended. He may find it

necessary to analyze his immediate superior's instructions pertaining

to the entire force of which his command is a part, and to consider,

also, the objectives indicated for other commanders, on his own

echelon, who also belong to that force.

On occasion, also, higher authority may acquaint the commander with

the general plan adopted by the superior, and may order action--such

as movement in a certain direction or to a certain locality--without

assigning a more definite objective. Should it happen in emergency

that later developments prevent higher authority from making such an

assignment, the commander may find himself under the necessity of

selecting, for himself, an appropriate objective, to be adopted by him

as if it were assigned.

Should the commander find that his instructions do not clearly

indicate an objective, or should he find that the one indicated is not

applicable under the circumstances of the case, he will select an

appropriate objective for his own guidance as if it were assigned by

higher authority. He will make such selection through use of the same

procedure already described herein as applicable to the selection of

an objective of any sort. In such case he puts himself in his

superior's place, in order to arrive at a reasoned conclusion such as

the higher commander, if apprised of the circumstances, would desire

to adopt. Circumstances permitting, the commander will of course

communicate with higher authority, and will make constructive

representations. (See page 15.)

The appropriate effect desired, as the first factor to be applied in

selecting such an objective, will naturally involve the objective

indicated in the general plan for the immediate superior's entire

force. This general plan is normally announced by the superior for the

guidance of the commander and of other commanders on the same echelon.

If, however, this further objective is not known to the commander, he

will endeavor to obtain a proper point of reference. To this end, he

will use his knowledge of the objective assigned to his immediate

superior, or of the further intentions of the higher command with

respect to the conduct of the operations, or of the campaign, or of

the war.

The provisions for the formulation of plans and orders (Chapters VII

and VIII) take account of the fact that the commander may require

definite information as to the objectives of higher echelons. In

organizations where a state of mutual understanding has been well

established, the commander will rarely be without some guidance in the

premises (see also page 33), by reason of the chain of objectives

indicated in plans and orders of the higher command (page 48).

From the viewpoint of the commander, this relationship among

objectives presents to him a series, from the present or immediate

objective to others more distant in time. Thus there may be one or

more intermediate objectives, leading away from the immediate one to

the ultimate objective, so far as the concern of the moment is

involved.

This relationship of immediate, intermediate, and ultimate objectives

may also exist in situations where the commander, operating on his own

initiative and responsibility, determines such a chain of objectives

for himself.

Such a situation frequently arises in a campaign or a major operation,

and is normal, also, as to minor operations (see page 56, as to

physical objectives).

As already observed, the relationship of objective and further

objective is the criterion for distinguishing between strategical and

tactical considerations, from the viewpoint of the commander concerned

(pages 9 and 10).

What has been noted in the foregoing as to the objective (singular) is

also applicable to situations where such an objective involves two or

more objectives collectively considered.

III. DETERMINATION OF EFFECTIVE MILITARY OPERATIONS

As noted with respect to the Fundamental Military Principle (page 41),

the effort required for the attainment of a military objective

involves military operations (page 37), whose salient features are

listed in the Principle. These features, including physical

objectives, relative positions, apportionment of fighting strength,

and freedom of action, will now be discussed to indicate how they are

correctly determined by the factors, also cited in the Principle,

pertaining to suitability, feasibility, and acceptability. Such

determination is accomplished through application of the corollary

Principle of Effective Military Operations (page 42).

Physical Objectives

Fundamental Considerations. An operation, however splendidly conceived

and faultlessly executed, involves waste of effort if directed with

relation to wrong physical objectives.

Since a physical objective constitutes the tangible focus of effort

(page 47) toward the attainment of the effect desired, its correct

determination is of paramount importance both before and during the

prosecution of operations.

As has been demonstrated (page 51), the consideration of possible

physical objectives (in space) is essential to the selection of

suitable objectives (in mind). Moreover, action with reference to one

or more physical objectives is the necessary basis for determining the

feasibility and acceptability of a plan.

Military objectives can be achieved only through the application of

power, actually or by threat (page 8), with reference to physical

objectives.

The determination of correct physical objectives is followed, if more

than one such objective is found, by the selection of the one or more

which are best adapted to the requirements of the situation. The

procedure for determination and for selection is a matter for

painstaking mental effort, based on the considerations now to be

presented.

The term "military objective" is frequently used in military

literature to distinguish physical objectives which are combatant in

character from those which are noncombatant. The considerations which

follow are applicable to physical objectives of all categories.

Procedure for Determination and Selection of Correct Physical

Objectives. In a particular set of circumstances, the field wherein

correct physical objectives may be found and the best selected, is

that of an existent or probable theater of action.

The determination of a physical objective, when correct, initially

satisfies the requirement of suitability with respect to the nature of

the objective,--this being, in such case, the appropriate effect

desired (page 31). Physical objectives not suitable, with relation to

the objective to be attained, are manifestly incorrect physical points

of orientation with respect to the operations involved in the effort

to attain such an objective.

It may be found, however, that the selection of a single physical

objective will not fulfill this requirement. A commander may find it

necessary to direct his effort simultaneously, or in succession, with

relation to more than one physical objective.

When a succession of physical objectives has to be dealt with, the

selection will necessarily include such a series. Such a case might

occur where a campaign has been found necessary in the form of

successive stages as essential features. The visualized termination of

each successive stage may be marked by the successful application of

effort with respect to one or more physical objectives. Such a series

of physical objectives may frequently also occur in operations on a

smaller scale; even in very minor actions such a succession of efforts

is normal. (See page 54, as to objectives.)

The choice as to the specific nature of physical objectives will

extend, for example, from the enemy's organized forces as a whole to

the physical body of an individual combatant. Within this range will

be included all manner of physical elements of enemy fighting

strength, singly and in combination, such as troops, ships,

geographical points, lines and areas, fortifications, bases, and

supplies.

The physical objective may take the form of a fixed geographical

position, the occupation of which, because of its inherent

advantages, may be, for example, an essential preliminary to further

progress. The position may, for instance, be merely a point in the

ocean (page 47), a rendezvous beyond which, although its occupation

may be uncontested, it has been deemed unwise to proceed without

further information or additional strength.

The physical objective, therefore, does not always take the form of

some element of the enemy fighting strength; not infrequently, the

occupation of a correct physical objective may be uncontested by the

enemy. However, intervening armed forces of the enemy may constitute

the physical objective for application of successful effort before a

further physical objective may be dealt with. The possibility of enemy

opposition may, therefore, place the selection of one or more physical

objectives on an indeterminable basis at the time of the original

solution of the problem. This may require a commander to defer his

choice until the situation has become more fully developed.

For example, his objective may be the occupation of a certain harbor,

preliminary to the establishment of a base. The harbor is then a

correct physical objective, perhaps the only physical objective which

need be dealt with, if there are no other obstacles to prevent or

interrupt the operation. Armed forces of the enemy may, however, stand

as an obstacle to the undisputed occupation of the harbor and,

therefore, to the attainment of the objective. In such case they

become, for the time being, the correct physical objective.

While the armed forces of the enemy may frequently present appropriate

physical objectives, this is not always the case (see above). It is

true that, in war, the armed forces of the enemy, until they can no

longer offer effective resistance, prevent the full attainment of the

objective of the State. Accordingly, from the broad viewpoint, they

may constitute the legitimate and proper physical objective of the

opposing armed forces. Armed forces of the enemy which are present in

opposition to any projected operations are likely to offer proper

physical objectives.

These facts, however, do not restrict a commander, in his choice of a

physical objective, to the armed forces of the enemy. Nor do these

considerations require him to search for and destroy the enemy forces

before directing his effort toward the attainment of an objective

under circumstances where the enemy is seen to be incapable of

presenting effective opposition.

The correct physical objective may change several times during the

course of an operation. This is particularly to be expected in a naval

tactical engagement of considerable scope. While the enemy fleet, as a

whole, may properly be considered in such a case to be the physical

objective, the component parts of each fleet, the types of vessels and

their combinations, may, from time to time, find in their opponents a

variety of physical objectives, the particular identity of which can

scarcely be predicted with assurance. It is here that the importance

of the correct selection of physical objectives stands out in bold

relief.

Infliction of loss on enemy forces, or support of own forces hard

pressed, may always seem tempting immediate objectives in war.

However, there may be occasions when disengagement or refusal to

engage an enemy force, even though it be of manifestly inferior

strength, may be appropriate to the attainment of the end in view.

Necessity for speed or secrecy, or other demands, may make the

required operations unacceptable. (See page 75 as to the offensive and

the defensive.)

Land, as the natural habitat of man (page 46), is always the principal

store-house of his indispensable resources, as well as the primary

scene of his activities. Naval operations, therefore, have always in

view the eventual maintenance or creation of a favorable military

situation in critical land areas. From this fundamental viewpoint, the

eventual physical objective of military operations is always a land

objective.

* * * * *

The suitability of a physical objective having been determined, the

next consideration is the feasibility (page 31) of taking such action,

with relation thereto, as will, if successful, attain the objective in

mind. Feasibility is determined by evaluation of the factors of means

available and opposed, as influenced by the characteristics of the

theater, in order to assess relative fighting strength (see page 52).

In connection with the effort involved with relation to any physical

objective, questions of feasibility may make it desirable or necessary

to visualize the detailed operations which arise from considerations

of relative position, of apportionment of fighting strength, and of

provision for freedom of action.

Of particular interest with respect to such operations, it is noted

that the premature disclosure of a selected physical objective is a

military error. By appearing, however, to operate against more than

one physical objective, a commander may lead the enemy to overstrain

his resources in the effort to protect them all. Thus the commander

may reduce the resistance to be encountered in dealing with what have

already, or may finally, become the selected physical objectives.

Feints in several directions may even divert all of the enemy's

effective defense from the vital points (see also page 68).

* * * * *

After the suitability of a physical objective has been established, as

well as the feasibility of the contemplated action with relation

thereto, such action is next considered from the standpoint of

acceptability with reference to the consequences as to costs. The

specific factors involved in acceptability as to consequences have

previously been mentioned (page 31).

* * * * *

When the requirements of suitability, feasibility, and acceptability

have been satisfied, the locality, the opposing force, or other

subject of consideration may be regarded as a correct physical

objective.

When more than one correct physical objective has been determined and

a choice is indicated, such selection will also be founded on the

foregoing requirements.

No doctrine, no advance instructions, can replace the responsible

judgment of a commander as to his correct physical objectives. On

occasion, higher authority may request recommendations (see page 42,

as to opinions) with respect to such objectives. The duty of a

commander to depart from his instructions under certain conditions,

and the grave responsibility which he thereby assumes, have also been

referred to (page 16).

Relative Positions

Fundamental Considerations. The relative positions occupied or

susceptible of occupancy by armed forces are matters which demand

constant and intelligent attention before and during hostilities.

Being fruitful sources of advantage or disadvantage, such relative

positions assume primary importance where enemy forces are concerned,

and are scarcely of less importance from the standpoint of the correct

apportionment of the subdivisions of one's own forces, and from the

viewpoint of their freedom of action.

During periods of actual tactical contact, the successful delivery of

the decisive thrust against selected physical objectives is greatly

furthered by the occupancy and maintenance of advantageous relative

positions.

The fundamental significance of relative position lies in the fact

that position is the basis of movement, for movement is merely a

change of position. Speed is the rate at which movement takes place.

The particular factors to be reckoned with are, therefore, time and

space. In skillful utilization of these elements lies the successful

employment of relative position in the creation or maintenance of a

favorable military situation, whether the movement be by land, sea, or

air (page 46).

The necessity for movement may be an important consideration in

determining possible or likely theaters of operations. Where

transportation between two or more positions within a certain area is

essential to the successful conduct of a war, the area which includes

the routes between these positions, or a portion of such routes,

becomes at once a possible or likely theater. Such an area may be

normally within the control of one or the other of the belligerents,

or the control may be in dispute. Certain of the positions themselves

may belong to neither of the belligerents. The area itself may be a

land area, or a sea area, or a combination of the two. It may be an

area which borders upon the sea, or an island area. In any case, the

air is a common characteristic.

The movement of a force is properly regarded, not as an even flow, but

as a series of steps from one position to another. The movement may or

may not be continuous. Pauses are usual, their occurrence and duration

being a matter dependent upon circumstances and calling for the

exercise of sound professional judgment. Intermediate positions may be

utilized, successively, so as to facilitate occupancy of the final

position which is the goal of that phase of operations (page 56). This

procedure often effects an ultimate saving of time. In many cases,

other advantages also may accrue.

The foregoing considerations are applicable to changes of position

whether in the direction of the enemy, toward a flank, or to the rear.

Flanking maneuvers and retrograde movements, both sometimes profitably

employed to decoy the enemy, may frequently be utilized to gain

advantageous relative position. The proper objective of each is the

maintenance of a favorable situation, or the alteration of an

unfavorable one, either locally or with reference to the larger phases

of operations, through measures involving apportionment of fighting

strength, or obtaining advantages of position, or retaining or gaining

freedom of action. Combinations of forward, flanking, or retrograde

movements are frequent in war, the skillful combination of the

offensive and the defensive (see page 75) being no less applicable to

the problem of relative position than to the other elements of a

favorable military operation.

Procedure for Determination and Selection of Advantageous Relative

Positions. Since the various positions to be occupied become physical

objectives for the time being, their proper determination and

selection are governed by the same considerations which apply to

physical objectives (see page 55 and following).

Thus, it becomes necessary to consider, first, as to suitability,

whether the position, once gained, will permit the attainment of the

appropriate effect desired.

Secondly, consideration is required as to feasibility. Are the

available means adequate to gain or to maintain such position? In

answering this question, due regard is paid to opposing means and to

the characteristics of the theater.

Finally, there is to be considered, as to acceptability, whether the

consequences as to costs, in terms of relative fighting strength, will

be such, if the position is gained or maintained, as to permit the

attainment of the objective. The possible effect of these consequences

on future action, whether the attempt succeeds or fails, may be

vitally significant.

* * * * *

With regard to suitability, the factor of the appropriate effect

desired calls for special consideration of the requirements with a

view to future action. This is true because of the relationship which

naturally exists between successive positions (page 60) if changes of

location from one to another are to be integrated into movement

calculated to accomplish the effect desired. Each position, itself for

the time being a physical objective, offers certain advantages or

involves certain disadvantages with relation to a further physical

objective. The position of the latter, in turn, presents possibilities

(or denies them) with respect to future movement. The influence of

considerations with respect to time (in addition to those noted above

with regard to space) is also a factor whose importance increases when

urgency is a matter of immediate concern.

With regard to feasibility, the technical capabilities and

limitations of the armed forces (page 67) are, of course, among the

principal factors. These capabilities and limitations are respectively

promoted and imposed primarily by considerations peculiar to the

particular medium of movement involved.

With specific regard to the areas within which military operations may

suitably be undertaken, the fundamental distinctions created by

recognized political sovereignty require attention. That part of the

surface of the earth which comprises its land area is recognized as

the property or the charge of one or another of the sovereign states,

although in certain cases the title may be in dispute. The air above a

nation's territorial domain is generally understood to be part of that

domain. The point to be observed is that there are no land areas which

belong equally to all nations. Accordingly; because of the factor of

neutral sovereignty, both land and air forces of belligerent States

may be under the necessity of following indirect routes to their

physical objectives.

In the case of the sea, however, all those portions of the earth's

surface which are covered by water (exclusive only of the recognized

territorial waters of the several nations), i.e., the high seas, are

presumably common property. The same applies to the air above the sea.

These considerations, and the fact that the surface of the sea is a

broad plane, permit open sea areas to be traversed by a variety of

routes to an extent not applicable in the case of land areas and the

air above them. In addition, the fact that technological developments

have been such as to permit movement, not only on the surface of the

sea and through the air above but also beneath the surface, gives

distinctive characteristics to the sea when considered as a theater of

operations.

The surface of the sea has, from the earliest days to the present,

provided roads over which human beings in greatest numbers and the

resources of the world in greatest weight and volume can be

transported in single carriers. From the standpoint of any belligerent

it is imperative that, during war, these roads be kept open to the

extent demanded by the needs of the State. It is equally imperative

that an enemy be deprived of the advantage which their use might

otherwise afford. In both cases localized (even though temporary)

control, not only of the surface but of the water beneath and the air

above, may be essential. It is pertinent, also, to note at this point

the interest of neutrals, or of unneutral nonbelligerent Powers, in

keeping open the trade routes via the high seas. Such interest may

constitute an important factor in the calculations of a belligerent

State.

Considerations of maximum capacity for speed represent the utmost

possibilities with respect to movements (i.e., change of positions)

(page 60) in a given medium within a given time limit. A knowledge of

maximum speed potentialities, one's own and those of the enemy, is

required if changes in position are intelligently to be made. A

knowledge of the variety of conditions, controllable and otherwise,

which affect or preclude the employment of maximum speed, is likewise

a requisite. Poor material condition, inadequate training, and

incorrect methods of operation are preventable or correctable. The

limitations on speed which are imposed by logistics, and by natural

obstacles such as the hydrography, the climate, the wind, the weather,

and the state of the sea, are susceptible of greatest possible

adjustment to circumstances only by the exercise of foresight and

judgment. All these conditions indicate the close relationship that

exists between relative position and freedom of action (page 70).

The same observations apply to considerations of maximum capacity for

endurance, the ability to operate without necessity for replenishment

from an outside source. Radius of action is decreased or increased

accordingly with resultant restrictions, or otherwise, on freedom of

action.

With respect to the freedom of action of armed forces, also a

consideration in relation to feasibility, the logistics of a military

operation, of whatever scope, constitutes a problem which begins when

the plan is in process of formulation. This problem ends only when the

necessity for sustaining the movement, and for retaining the position

gained, no longer exists.

Ships and other means of conveyance, surface, subsurface, and air, are

incapable of providing the necessities of life and the implements of

warfare beyond the capacity built into them. Operations which extend

beyond the limits of such capacity must cease unless replenishment and

support, possible only from other sources, are provided. The logistics

problem may be so difficult as to cause rejection of a course of

action involving distant operations. From the standpoint of supply,

military movements by land, sea, and air are, therefore, vitally

associated with positions on land and with their relation to the area

of operations (see also page 58).

The same observations apply in larger scope to the State itself,

which, because of economic vulnerability with respect to certain

essential raw materials, may be compelled to seek support from outside

sources lest supplies on hand become exhausted. In all cases, great

importance attaches to the geographical location of sources of supply

in their relation to a required point of delivery and to the routes

which lie between.

It follows that enemy sources of supply may be suitable physical

objectives (see page 56). Their destruction or capture, or the

severance of the enemy's lines of communication with them, may

seriously restrict his freedom of action.

From the standpoint of the relative position of its features, and

apart from their inherent military value, the characteristics of the

theater of military operations may exert an important influence upon

the shaping of events. Each characteristic merits consideration as a

potential means of facilitating or obstructing movement. Some

localities may have been developed as repair, supply, or air bases.

Others may be sources of essential raw materials. Certain points may

be heavily fortified. Island formations may be valuable to either

opponent, or to both, because of the capacity and security of their

harbors, the character of their terrain, or their positions relative

to each other. The inherent military value of the several features of

the theater may be enhanced or vitiated by the relative position which

each occupies with respect to other features, and with reference to

the location of the armed forces involved.

So-called "strategic points", historically significant in connection

with military operations, derive their importance by reason of their

relative position with reference to routes of movement.

The possibilities of utilizing or of changing the characteristics of a

theater of operations, to assist, hamper, or deny movement, are

governed by considerations previously discussed (see the Principle of

the Proper Physical Conditions to be established in the Field of

Action--page 34).

In planning the creation or maintenance of a favorable military

situation from the standpoint of relative position, there may,

therefore, profitably be included an examination into:

(a) The relation which may exist between the geographical location of

the subdivisions of one's own forces and

(1) Those of the enemy,

(2) Geographical areas under one's own control, and

positions within those areas,

(3) Geographical areas not under one's own control, and

positions within those areas,

(4) Areas coveted or in dispute,

(5) Fixed actual and potential repair and operating bases

and sources of supply and replenishment, own and enemy,

controlled or otherwise.

(b) The relation existing among the geographical locations listed

immediately above, including the effect of possible changes in

control.

(c) The bearing of the sun and moon, and the direction of the wind and

sea.

(d) The length and vulnerability of possible lines of communication.

(e) The time and distance, and resulting relative speeds, involved in

movements necessary to change or to maintain an existing relation.

(f) The measures incident to adequate freedom of action.

A more detailed analysis of the factors influencing relative position

is made in Section I-B of the Estimate Form (Chapter VI).

* * * * *

In connection with the factor of consequences as to costs, the

requirement as to acceptability is a weighing of expected gains and of

reasonably anticipated losses, a balancing of the one against the

other, with due attention to the demands of future action, (see page

61).

Military movement normally involves an inescapable expenditure of

military resources. The characteristics of the theater, alone, will

exact their due toll, even if no enemy be present. In the presence of

the enemy, such expenditures may increase with great rapidity. The

fundamental consideration here is whether the resultant losses are

disproportionate to the gains.

Avoidance of movement is frequently the correct decision, because

movement, if it offers no advantages, is scarcely justifiable even if

it entails no material loss. Movement, merely for the sake of moving,

is not a profitable military operation. However, the conduct of

military operations without major movement is a concept inherently

defensive (page 75), even apathetic, whose outcome, against an

energetic enemy, can rarely be other than defeat. In the execution of

advantageous movement to achieve correct military objectives, the

competent commander is always ready to accept the losses which are

inseparable from his gains.

* * * * *

The foregoing considerations as to advantageous relative positions are

applicable, not only in the realm of the commander's decisions as to

his own action, but also to his judgments rendered when higher

authority calls for recommendations (see page 42).

Apportionment of Fighting Strength

Fundamental Considerations. The assignment of a task may be expected

to carry with it availability of fighting strength deemed adequate by

higher authority for accomplishment of the operation involved.

In appropriate instances, the higher command may call for

recommendations as to the amount and character of the means deemed

adequate by the subordinate for performance of the task with which he

is, or is to be, charged (page 42).

In any case, means having been made available, it remains for a

commander to whom an objective has been assigned to apportion these

available resources in such manner as to provide the requisite

strength at points likely to be decisive, without unduly weakening

other points. In effect, he is charged with a practical adjustment of

means to ends. This responsibility is discharged by the effective

utilization of means and prevention of waste nicely balanced through

full consideration of all essential elements of a favorable military

operation. The procedure involved has been indicated (see the

corollary Principle for the determination of the Proper Means to be

Made Available--page 34).

The relation between the strength to be brought to bear in dealing

with a selected physical objective, the tactical concern of the

moment, and that necessary to the attainment of the strategical aim

(see pages 9 and 10), constitutes a fundamental consideration in

effecting such a balance.

In making a correct apportionment, there will be involved not only the

physical elements of fighting strength, but the mental and moral as

well. With respect to mental and moral factors, the capabilities of

particular commanders and organizations may be an important factor in

apportioning forces to tasks. In the physical field, numbers and types

occupy a prominent position, each however, requiring consideration

from the standpoint of the existing situation.

Thus, forces composed of appropriate types and suitably equipped and

trained may exercise greater effect than numerically larger forces not

so well adjusted to the requirements of the situation. On the other

hand, numerical considerations become predominant under conditions

otherwise substantially equal.

These considerations, viewed in the light of the relationship of naval

operations to land areas (page 63), indicate the importance which may

attach to immediate availability, with a naval force, in addition to

its own air strength, of a proper complement of land forces (with

appropriate air strength) which are organized, equipped, and trained

for amphibious operations.

The same considerations point also to the vital importance of due

provision, with respect to the armed forces of a State, for joint

operations involving concerted action on land, by sea, or in the air.

In connection with the capabilities of particular commanders (page

66), it will be appreciated how important it is, more especially in

amphibious or joint operations, for responsible officers to have a

correct understanding of the powers and limitations of the several

types of military forces involved, be their primary medium of movement

the land, the sea, or the air.

Factors of dispersion and concentration are also involved in

apportionment of fighting strength.

While undue dispersion may result in lack of adequate fighting

strength where required, a certain degree of dispersion may be

necessary to meet the demands of movement and of freedom of action.

Serious errors in this regard, however, may result in inability to

furnish support where needed, and in consequent punishment or

isolation of one or more valuable detachments.

In distant operations some dispersion is required to safeguard long

lines of communication. The requirements for this purpose may

sometimes be so great that, unless the total available strength is

adequate, a due apportionment to the guarding of long lines of

communication may so weaken the main force as to prevent the

attainment of the objective. (See also page 63.)

Proper dispersion is, therefore, a requirement to be met, while undue

dispersion is to be avoided. But realization is also necessary, in

this connection, that there is an equal danger in over-concentration.

An undue concentration of means at any point may subject such a force

to unnecessary loss. Another disadvantage may be lack of adequate

fighting strength elsewhere.

Accordingly, axiomatic advice that it is unwise to divide a total

force, while containing a sound element of caution, is misleading and

inadequate, for division is often necessary or desirable. To be

adequate, a maxim or rule relating to division of force should

indicate when, and in what measure, such division may or may not be

necessary or desirable. (See also page 25.)

Similarly inadequate, however true as a generality, is the statement

that the requirements of effective warfare are met by bringing

superiority to bear at the decisive time and place. Such an injunction

is of little assistance in solving practical problems as to the

appropriate degree of superiority, and as to the proper time and

place.

In like manner, any rule is faulty which advises a commander to seek

the solution of his problems by always bringing to bear his elements

of strength against the hostile elements of weakness. It may be found,

on occasion, that it is necessary or desirable to act with strength

against strength.

But it is equally faulty to maintain that action, to be effective,

seeks always to deal with the enemy by first destroying his elements

of strength. Even when the strongest opposition cannot be defeated by

direct action of this nature, success may still be possible by first

disposing of elements of weakness. When the stronger elements of a

hostile combination cannot be defeated without undue loss, yet cannot

stand without the weaker, consideration may well be given to an

apportionment of fighting strength on the basis of seeking a decision

against the latter. The defeat of a relatively small force at a

distance from the area where the main forces are concentrated in

opposition, may hasten the attainment of the ultimate objective.

The main effort, where the greater force is employed, may be identical

with the effort contributing most directly to the final result. This

identity, however, does not always exist, and the decisive influence

is frequently exerted by a relatively small force, sometimes at a

distance from the principal area of action.

Diversions (see also as to feints, page 59) are not likely to be

profitable unless constituting a sufficient threat, or unless offering

apparent advantages to the enemy which he feels that he cannot forego.

Success will attend justified diversions if they lead the enemy to

reapportion his fighting strength to meet the threat, either because

he expects repetitions (see page 73, as to raids), or because the area

involved may become a new theater of action, or for other pertinent

reasons.

Means which are inadequate for the attainment of an objective if used

in one effort may sometimes be rendered adequate by utilizing them in

a series of successive impulses. Similarly, the effect of employing

means otherwise adequate may be intensified by the delivery of attacks

in waves.

Procedure for Determining Proper Apportionment. The fundamental

considerations outlined above as to apportionment of fighting strength

have application both to the offensive and the defensive (see also

discussion on page 75). As to all of these considerations, the

solution for the particular situation is to be found only through an

analysis of the factors applying to the particular problem.

Thus, the first consideration relates to suitability, and requires

that the apportionment of means be suitable both as to type and as to

amount, in order to produce the appropriate effect desired in view of

the means opposed and of the influence of the characteristics of the

theater. The fundamentals involved, applicable in all human activities

(see the Principle of the Proper Means to be Made Available--page 34),

are the factors cited above. These are also, of course, indicated in

the Fundamental Military Principle.

The correct apportionment may also be influenced by any military

changes to be effected in the characteristics of the theater (as

indicated in the Principle of Proper Physical Conditions to be

Established--page 34). Thus, the establishment of a well defended base

may operate, properly, to reduce the requirements for apportionment of

a force for a particular duty in that locality. Similarly, the proper

use of fortifications, obstacles, demolitions, and routes by land,

sea, and air, as well as facilities for exchange of information and

orders, all operate to increase fighting strength relative to that of

the enemy.

The next consideration, that of feasibility, takes account of the type

and of the amount of means that can be apportioned in view of the

means available.

In connection with the foregoing there will be appropriate

requirements for the operation as a whole and for its component

operations. All of these requirements may call for analysis of the

relative positions to be utilized, with reference to the selected

physical objectives, and of the requirements for adequate freedom of

action.

Finally, the requirement of acceptability as to the factor of

consequences will call for consideration of the results of the

allotments of forces to particular tasks. This is necessary in order

to arrive at reasonable conclusions as to the military costs involved

either in event of the success of the effort or in event of its

failure, and with respect, more especially, to the effects on future

action.

The attainment of the objective, however suitable as to the effect

desired, may be found, on the basis of due study, to be infeasible or

to involve unacceptable consequences. The inescapable conclusion is

then that an increase in relative fighting strength is required or

that another objective, feasible of attainment and acceptable with

respect to consequences, is necessarily to be adopted (see page

52-53).

Freedom of Action

Fundamental Considerations. In providing for proper apportionment of

fighting strength, a commander may attain the end in view by

increasing the physical, mental, or moral elements of his own

strength, relative to the enemy's, or by decreasing the enemy's

strength through imposing restrictions on hostile freedom of action.

Freedom of action will enable a commander to prosecute his plan in

spite of restrictive influences. That enemy interference will, to a

greater or less extent, impose restrictions on freedom of action is to

be expected. Restrictions may also be imposed by physical conditions

existing in the theater of operations, and by deficiencies and

omissions which are within the field of responsibility of the

commander to correct.

Even with fighting strength adequate to overcome enemy opposition and

physical handicaps, deficiencies and omissions within a commander's

own field may become effective checks to further progress unless

avoided through the exercise of foresight. To this end, it is

desirable to consider certain possibilities which are likely to

promote freedom of action if properly exploited, and to restrict it if

neglected.

To a considerable extent, a commander has within his own control the

degree of influence which his force will exert in the creation or the

maintenance of a favorable military situation. The power applied by a

military force is determined not only by the fighting strength of its

component commands, but also by the degree of coordination of their

several efforts in the attainment of the objective (see also page 12).

Whatever the inability of the commander to influence the other aspects

of a situation, the ability of his command to act unitedly is a matter

largely in his hands.

When time permits, subordinate commanders, apprised of contemplated

tasks in general terms, may be called upon to submit recommendations

as to the detailed instructions to be issued them, as well (page 66)

as to the means to be allotted for the purpose. By this procedure,

individual initiative (page 15) is fostered and the higher command

enabled to utilize the first-hand knowledge and experience gained on

lower echelons without, however, divesting the higher command of any

of its responsibility.

The command system may provide for unified action through unity of

command or through cooperation resulting from mutual understanding. On

the assumption that commanders are competent and that communications

are adequate, unity of command is the more reliable method. However,

it cannot be obtained everywhere and at all times, because of the

necessary decentralization of the command system in areas distant from

the commander. In such areas, unity of effort may sometimes be assured

by provision for local unity of command. At other times, unity of

effort may depend entirely on cooperation between adjacent commands

within the same area. (See page 12.)

Organization (see page 13), the mechanism of command, is most

effective when, through the establishment of authority commensurate

with responsibility (page 12) and through the assignment of tasks to

commanders with appropriate capabilities (see also page 66), the

highest possible degree of unity of command is attained. The command

organization and mutual understanding are of primary importance as

methods of ensuring maximum power with available fighting strength,

and of affording consequent maximum contribution to freedom of action.

Deficiencies in technical training are capable of imposing grave

restrictions upon freedom of action. Material equipment, even though

it may represent the acme of perfection in design and construction,

will not surely function unless skillfully operated and maintained.

Even though mobility and endurance be otherwise assured, the capacity

which they represent is not susceptible of effective employment unless

the methods of movement, i.e., of effecting change in relative

position (page 59), are intelligently planned and are developed to a

point which assures facility of operation when in the hands of skilled

personnel.

Tactical training, not omitting that required for joint operations

(page 67), is one of the vital factors of fighting strength, with

respect, more especially, to its contributions to freedom of action.

A state of high and stable morale (page 9), founded upon sound

discipline, is an invaluable characteristic of fighting strength. An

understanding of the human being is therefore an important feature of

the science of war.

Discipline, in its basic meaning, is the treatment suitable to a

disciple. The objective of discipline is therefore the creation and

maintenance of the spirit of willingness to follow where the commander

leads. The exercise of leadership is not restricted, however, to those

occasions when the commander can be physically present. The exigencies

of war and the requirements of control prevent the commander from

being always, personally, in the forefront of action. These

restrictions as to considerations of space however, impose no

limitations on leadership in terms of time.

The influence of the competent commander is a factor always acting to

shape the situation according to his will (page 47), though the

necessities of the moment may compel his presence elsewhere. The

ability to create and maintain a faithful following who will execute

the commander's will wherever he may be (page 15) is, accordingly, a

primary attribute of command.

With this objective in mind, the true disciplinarian runs no risk of

confusing harshness with the exercise of justice. He understands the

difference between an overbearing arrogance, arising from unconscious

ignorance, and the pride which springs from a justified self-respect.

He appreciates the distinction between mere stubbornness, which would

alienate his followers, and the necessary firmness which binds the

bonds between the leader and the led. He realizes that comradeship,

without presumptuous familiarity, is the firmest foundation for mutual

loyalty (page 14). He knows that kindness and consideration, without

suggestion of pampering, will not be mistaken for weakness by any

subordinate worthy of the name.

Military subordination, which implies a proud obedience without trace

of servility, is the essential basis for the development of the

qualities of command. It is an old adage that, to know how to command,

one must know how to obey. In the profession of arms, every man is at

once a leader and a follower; the uncertainties of war may suddenly

confront any individual, even on the lowest echelon, with the call to

exercise command.

The requirements of sound discipline are thus the correct basis for

all training. By proper training of his command, by instilling in it a

spirit of resolute determination and by otherwise fostering its

morale, and by weakening the morale of the enemy, a commander may

increase his own fighting strength and reduce that of the opposition.

When a command is inured to the ill effects of fear, despondency, lack

of confidence, and other weakening influences, it may more effectually

employ measures calculated to upset the morale of the enemy.

In connection with these measures, surprise, when judiciously

conceived and successfully employed, may be a most potent factor.

Surprise (see page 26) is the injection of the unexpected for the

purpose of creating an unfavorable military situation for the enemy.

Its effect is particularly telling when it results in disruption of

enemy plans, and thus promotes the execution of one's own.

The raid, an offensive measure swiftly executed, often by surprise,

and followed by a withdrawal, may be a valuable operation when

employed to attain objectives within its capacity. The collection of

information, the destruction of important enemy equipment or supplies,

the neutralization of enemy positions, the severing of physical means

of communication and transport, and the like, are suitable objectives.

The attritional effect of repeated raids may be very great. Skillfully

executed raids frequently produce panic among the populace and thus,

by political pressure, cause a change in the existing apportionment of

fighting strength to the extent of upsetting military plans in other

theaters. This is particularly likely to occur when there is fear,

justified or otherwise, of repetition (see page 69).

However, because a raid necessarily includes a withdrawal and cannot,

therefore, accomplish the occupation of territory (see page 46), it

can have only indirect bearing, however important, upon the final

outcome of the hostilities against a strong and competent enemy. Like

other forms of surprise, the raid, injudiciously employed, may serve

only to disclose one's presence, and thus to betray more important

future plans. If the raid fails to attain its objective, it may even

strengthen enemy morale.

The form which surprise may take is not confined to the stratagem, the

ruse, or the sudden appearance. Any unexpected display of novel

methods or of fighting strength, moral, mental, or physical, the

last-named sometimes assuming the character of new and especially

effective weapons or equipment, is included in the category of

surprise. The potential value of such methods or weapons is, however,

reduced or even completely vitiated by the leakage of advance

information concerning them, not only as to their details, but as to

the fact of their existence.

Other conditions remaining unchanged, an offensive surprise measure is

therefore more likely to be effective when the opponent has not been

given time to prepare a defense against it. On the other hand, where

there is knowledge that an opponent or possible opponent is taking

steps of a new or unusual nature and no adequate defense is prepared,

the equivalent of surprise has been granted him.

Security measures are necessary in order to minimize or prevent

surprise, or to defeat other efforts aimed at disruption of plans.

Protection brings security; its basic objective is the conservation of

fighting strength for future employment. Primarily requiring the

maintenance of secrecy and the exercise of vigilance and foresight,

security may be furthered by efficient scouting, by appropriate

dispositions and formations within the command, and by the use of

protective detachments and of various types of works in the sphere of

engineering. Previous discussion (pages 64 and 69), with respect to

relative position and to the apportionment of fighting strength, has

indicated how, through fortification and related measures, the

commander may increase relative fighting strength and thereby promote

his own freedom of action while restricting that of the enemy.

A commander will be hampered in maintaining his fighting strength at

its maximum unless he has arranged for, and has at his disposal,

adequate logistics support. Because of its intimate relationship to

mobility and endurance, such support is an essential to freedom of

action. Logistics support requires provision for procurement and

replenishment of supplies, for evacuation, proper disposition, and

replacement of ineffective personnel, and for material maintenance.

Freedom of action is restricted beyond those limits to which logistics

support can be extended. (See page 63.)

The initiative is of paramount importance in ensuring freedom of

action. If the initiative is seized and maintained with adequate

strength, the enemy can only conform; he cannot lead. If initiative is

lost, freedom of action is restricted in like measure.

The offensive, properly employed, is a method of seizing the

initiative, and of regaining it if lost. Even though there be an

actual numerical superiority in fighting strength, an offensive will,

however, seldom assume practical form unless founded on an offensive

mental attitude, which ever seeks the favorable and suitable

opportunity to strike. Completely to abandon the offensive state of

mind is to forswear victory.

Whether physically on the defensive or the offensive, the competent

commander is always engaged in a mental and moral attack upon the will

of the enemy commander (see page 8). By effective attack upon the

hostile will, the commander disintegrates the enemy's plan, i.e., the

enemy's reasoned decision, as well as the detailed procedure on which

the enemy relies to carry this decision into effect.

It does not follow that offensive action is possible or even desirable

under all circumstances. Even with superior strength the most skillful

commander will scarcely be able, always, to apportion forces in such

manner as everywhere to permit the assumption of the offensive.

Without adequately superior strength, it may be necessary to adopt the

defensive for considerable periods. If the offensive mental attitude

is retained, together with fixed determination to take offensive

measures as soon as appropriate to do so, the calculated and

deliberate adoption of the defensive, for the proper length of time,

may best promote the ultimate attainment of the objective. It is of

the utmost importance, however, that a static defensive be not adopted

as a settled procedure (see page 65) beyond the time necessary to

prepare for an effective offensive.

Both the offensive and the defensive have their places in an operation

whose broad character is primarily either defensive or offensive. In

operations which involve movement over a considerable distance, a

combination of the offensive and the defensive is usually found

necessary (see also references to distant operations on pages 63 and

74). Though the movement itself be offensive, the ensurance of freedom

of action may require both defensive measures and tactically offensive

action. The enemy, primarily on the defensive, may be expected to

seize every opportunity to employ the offensive.

Thus, a judicious combination of the offensive and the defensive has

been found to be sound procedure (see also page 61), provided that the

general defensive is always viewed as a basis for the inauguration, at

the proper moment, of the offensive. The methods employed during the

period of the defensive are best calculated to promote freedom of

action if they are designed to facilitate a ready assumption of the

offensive as soon as conditions favorable to the offensive have been

created.

Familiarity with the physical characteristics of the actual and

possible theaters of operations, and accurate intelligence of the

strength, distribution, and activities of enemy forces likely to be

encountered, are of primary importance in the promotion of freedom of

action. Additions to this store of knowledge may be made by a

continuous interpretation and dissemination of new information

collected, analyzed, and evaluated by persistent effort. Of equal

importance is the denial of information to the enemy.

In connection with counter-information measures (see page 127), the

scrutiny of information of a military nature intended for popular

consumption demands the exercise of sound professional judgment prior

to publication. A resourceful enemy is ever alert to evaluate and turn

to his own advantage all available information, including that

ostensibly innocuous.

As to all of the foregoing considerations, a fund of professional

knowledge, previously acquired through study, or experience, or both,

and coupled with a sound concept of war, is the best basis for

devising suitable, feasible, and acceptable measures for freedom of

action.

With a given fighting strength, the ensurance of freedom of action,

within the field of responsibility of a commander, requires

consideration of such matters as:

(a) Efficient provisions for exercise of command,

(b) Effective training,

(c) A state of high and stable morale, founded on

(d) sound discipline,

(e) The offensive spirit,

(f) The initiative,

(g) Surprise,

(h) Security,

(i) Adequate logistics support,

(j) Adequate intelligence and counter-intelligence.

A more detailed analysis of such factors is provided hereafter

(Chapter VI, as to Section I-B of the Estimate Form). With proper

provision made in these respects, the commander will be better able to

deal with those restrictions on freedom of action imposed by the enemy

and by adverse geographical conditions. With respect to restrictions

that in a particular situation may be due to the latter cause, it will

at once be appreciated how greatly freedom of action may depend on the

selection of correct physical objectives, on utilization of

advantageous relative positions, and on an effective apportionment of

fighting strength.

Each measure, or each operation, for freedom of action, if it is to

meet the requirements of suitability, feasibility, and acceptability,

will be planned on the basis of the foregoing considerations and will

take account, also, of the inherent requirements of that measure, or

operation, for freedom of action for itself.

On occasion, higher authority may request the recommendations of the

commander (see page 42, as to opinions) with reference to provision

for freedom of action. Such recommendations will properly be based on

the elements considered in the preceding discussion.

IV. SUMMARY

All these considerations involve the proper evaluation of the factors

applicable (page 25) to the particular problem. Each objective, prior

to its selection, and each operation, prior to its adoption, will

require examination of its suitability with regard to the appropriate

effect desired; of its feasibility with respect to the action

contemplated as to physical objectives, relative positions, the

concurrent apportionment of fighting strength, and freedom of action;

and, finally, of its acceptability with reference to consequences as

to costs.

CHAPTER V

THE FOUR STEPS IN THE SOLUTION OF A MILITARY PROBLEM

Chapter V discusses the four steps in the application of

mental effort to the successful attainment of a military

objective. Emphasis is placed on such matters as: the Estimate

of the Situation in basic problems, together with certain

details as to tasks, the mission, courses of action, and the

Decision; the formulation of detailed plans, including

subsidiary plans; directives; the Running Estimate of the

Situation; and the use of Forms in the solution of problems.

In Chapter II it has been brought to notice that every problem,

regardless of its type and scope, has its source in a perplexity

created by an apparent difficulty inherent in a situation. Where there

is a sufficient incentive to change or maintain the situation, the

problem is one which requires solution. (See page 20.)

A situation may be actual or assumed. In broad outline, an actual

military situation is always likely to present a picture of opposing

organizations of human beings, each possessed of fighting strength and

disposed in a locality or localities which constitute relative

positions with reference to each other.

This picture may be expected to assume various aspects as action

progresses (see page 38). The concern of the commander is to control

the unfolding of the original situation, to the end that he may attain

the effect he desires (page 72). (See also Chapter IX.)

The incentive to solve a problem is provided by a realization, on the

part of the individual concerned, of a need to make provision for the

attainment of an objective. In the ease of a military problem, such

incentive may result (1) from a directive issued by higher authority,

usually in the form of an assigned task, or (2) from the fact that a

decision already reached by the commander has introduced further

problems, or (3) from a recognition of the demands of the situation.

(See page 44.)

An objective is best attained by the successful application of

properly directed effort. There is thus an essential and continuing

relationship between the incentive to solve a problem, and the task

which assigns the objective (or objectives) and thus motivates the

procedure necessary for the attainment of the objective(s) so assigned

(page 50).

Such a task may, therefore, be referred to as the motivating task.

The natural mental processes which normal human beings employ in

solving their problems of business, public affairs, or even personal

matters, have been previously described as the natural processes for

employment in the solution of military problems (see Chapter II). In

adapting these natural processes to military requirements (page 43),

the only difference imposed is that of studied insistence that the

factors peculiar to the conduct of war, as recognized in the

Fundamental Military Principle (page 41), receive thorough analytical

treatment from the professional viewpoint.

The same observations apply when the field of military operations is

restricted to that which primarily concerns the naval branch of the

military profession. No fundamental difference in the solution of

problems is introduced thereby. The only variations in the application

of the Fundamental Military Principle are those due to the fact that

the sea provides the theater of naval operations with distinctive

characteristics (see page 62).

The Approach to the Solution

Studies of the subject indicate that the successful attainment of an

assigned military objective involves the application of mental effort

in four distinct steps (see page 3), in fixed sequence, as follows:

(1) The selection, by the commander, of a correct objective

(or objectives) by achieving which he may attain his

assigned objective(s). Such selection includes the

determination, in proper detail, of the action required.

(2) The resolution of the required action into detailed

military operations.

(3) The formulation of a directive, or directives, with the

intention of immediately inaugurating planned action.

(4) The supervision of the planned action.

In the chapters which follow, the fundamental procedure distinctive of

each of these steps will be treated separately and in the sequence

shown. The sequence of the steps is fixed because of the consequential

nature of the relationship among the procedures distinctive of the

several steps. The complete solution of a problem involves,

necessarily, all four steps. Each step deals with a distinctive type

of problem, or problems, pertaining to an aspect of the comprehensive

problem whose solution requires all four steps. No step after the

first can properly be undertaken unless the included problems involved

in the preceding steps have been solved.

It does not follow that the completion of one step necessarily

requires that the next step be undertaken immediately. It will be

seen, for instance, that the first two steps are concerned with

planning, the latter two more especially with execution. It is not

always necessary that a plan be executed; it may be drawn up as a

precautionary measure.

It is possible, therefore, that the first step only may be taken;

i.e., that the procedure for the attainment of a particular assigned

objective may be determined for the sole purpose of making provision

against a contingency, at that particular time merely an obscure

probability. Or, as may frequently be the case during peace, the

procedure may terminate, for the time being, with the completion of

the second step. In such cases, certain of the necessary military

operations are worked out in the desired detail as a provision against

future possibilities, are listed, and filed for reference as needed.

Parts II and III, which follow, deal primarily with the solution of

those problems of the naval commander which require familiarity with

the entire process, i.e., all of the four steps given above.

For simplicity of presentation, the procedure is described throughout

from the mental standpoint of the same commander. The arrangement of

subject matter conforms to this basis. The several types of problems,

classified according to the source of the incentive (page 79), are

discussed in connection with the appropriate step. When a problem

typical of a previous step arises during the process, the sequence of

steps is interrupted thereby, but is resumed by a mental return, on

the part of the commander, to the proper earlier step.

The First Step

The mental procedure distinctive of the first step (more fully

discussed in Chapter VI) deals with the usual case where a commander

becomes acquainted with the nature of his assigned objective through

receipt of a directive from his immediate superior, ordinarily in the

form of an assigned task or assigned tasks. In the discussion of the

first step, this most likely type of problem is chosen for

description, i.e., the one where the motivating task (see page 80)

comes directly from the immediate superior.

For purposes of reference, this problem may conveniently be termed a

basic problem. In such a case the original situation which gives

character to the problem may be similarly referred to as the basic

situation. The full solution of a basic problem always involves a

basic estimate of the situation, a basic Decision, a basic plan of

operations, and one or more basic directives. It may, as will be

shown, also require certain additional directives.

The military Estimate of the Situation, based on the natural mental

processes (pages 19-20 and 43), is introduced in the first step. The

reason for making such an Estimate is to provide a basis for a plan to

accomplish the assigned task. The Estimate constitutes a systematic

procedure for selection of a correct objective (or objectives),

suitable to the appropriate effect desired, feasible of attainment,

and acceptable as to the consequences involved in its achievement. The

selection of such an objective or objectives involves, incidentally

(see page 44), the determination, in the proper detail, of the action

required.

This estimate procedure is founded on the Fundamental Military

Principle (page 41). The procedure is the same as previously indicated

for the correct selection of objectives (Section II of Chapter IV).

On the basis of a summary of the situation, a recognition of the

incentive, and an appreciation of the assigned objective(s) (page 79),

the estimate of a basic problem enables the commander to obtain,

first, an understanding of (page 43) the appropriate effect desired.

As a result of this procedure, he can then correctly formulate his

mission (discussed hereinafter).

For the further understanding of all details pertaining to the

situation (page 43), the estimate next determines relative fighting

strength through a survey of the means available and opposed, as

influenced by the characteristics of the theater.

With the basis for solution of the problem thus established, the

actual solution (page 44), conforming to the system indicated in the

Fundamental Military Principle, starts with consideration of pertinent

methods of procedure, as tentative solutions of the problem. These

take the form of military operations, each denominated a course of

action (discussed in detail hereinafter). Each such course embodies,

specifically or inferentially, an objective to be achieved for the

attainment of the appropriate effect desired. Each course also

indicates, in proper detail, the action to be taken. Every pertinent

course of action is tested to determine whether it meets the

requirements of suitability as to the appropriate effect desired, of

feasibility on the basis of relative fighting strength, and of

acceptability with respect to the consequences as to costs.

Enemy courses of action are subjected to the same treatment.

Each course of action which passes the tests is compared with each

retained enemy course, after which those courses of action not

rejected on this basis are compared with each other. The best is then

selected and embodied in the Decision.

The Decision, accordingly, expresses a general plan of action (or

provides a basis therefor), including the commander's general

objective (page 49) for the attainment of the assigned objective. The

Decision also indicates, in proper detail, the action to be taken.

The estimate procedure is applicable not only to the problem of the

first step, viewed as a whole, but also to the numerous included

problems. These present themselves during the procedure of solution,

and call for "estimates within the estimate".

For example, the proper nature of the objective embodied in the

assigned task (discussed hereinafter), if not clear in the directive

received, may be determined by the use of the natural mental

processes. This is done through the application of the Fundamental

Military Principle, as previously described (page 52).

Similarly, the solution of the included problems as to the salient

features of the operations involved (correct physical objectives,

etc.) can be arrived at through the same processes. The procedure is

that indicated previously (in Section III of Chapter IV).

The estimate procedure may, however, be somewhat varied, as to

details, in accordance with the nature of the problem. Such adaptation

is applicable, for example, as to the special features which

distinguish certain types of strategical and tactical problems.

Every military situation has both strategical and tactical aspects

(see discussion of strategy and tactics, pages 9 and 10). The

character of the effort to be exerted at a particular time, and the

nature of the objectives to be attained, may be governed chiefly by

strategical, or chiefly by tactical, considerations. This fact may

affect details in the estimate of the situation, e.g., as to the

weight to be given various factors.

The essential difference between strategy and tactics has been shown

to lie in the end in view. It follows, then, that estimates of broad

strategical situations and of localized tactical situations tend to

differ from each other. The former lead to decisions as to such

matters, among others, as whether a battle shall be fought. The latter

lead to decisions, among others, as to the comprehensive tactical

methods to be followed in furtherance of strategical aims. Certain

distinctions of method as to such estimates are noted hereinafter with

respect to the analysis of fighting strength and with reference to

courses of action.

Tasks. The assignment of tasks to subordinates is an essential

function of the chain of command, applicable to all of the echelons of

command, from the highest to the lowest (page 12). On the lowest

echelons, such as that of a gun's crew or a fireroom watch, operations

thus prescribed involve numerous small specialized tasks, each

requiring the performance of a simplified routine by a few trained

men. Although earlier training in the performance of such tasks is

calculated to remove the necessity of solving the problems of the

lowest echelons in the four studied steps stated above, it is only

when the same methods of logical thought have previously been applied

to the solution of these problems that this state of affairs can be

brought about.

Properly conceived, each assigned task indicates, either specifically

or inferentially, an objective (or objectives). The relationships

existing among the echelons of command, with reference to objectives,

have previously been noted. (See page 48.) These relationships,

because a correctly conceived task specifies or infers an objective,

are equally applicable as to such tasks.

The manner of expressing tasks calls for special comment (see also

page 53, as to expressing objectives).

The commander may find in the expression of his task a statement,

only, of the action required. For example, the order "Proceed toward

the enemy battle line" involves movement, indicating merely a change

in relative position. No provision appears as to a future condition or

state of affairs.

Again, the task may be expressed as an order to "Attack the enemy

battle line." In this case, the enemy battle line is the physical

objective, but no specific future condition to result from the attack

is indicated. Here the action and the physical objective are given,

but the objective is left to be inferred.

If the commander can ascertain, from the directives he receives, his

task expressed in terms of accomplishment, he may be able to

visualize the action, the physical objective, and the condition to be

created. The order "Destroy the enemy battleship" (indicating, as the

objective, "the destruction of the enemy battleship"), results, when

successfully completed, in a new condition which is the objective of

the action against the physical objective.

Accordingly, a task expressed in such terms of accomplishment conveys

precise information as to the objective; yet such an expression of the

task does not prevent freedom of action, with opportunity for exercise

of initiative. The commander who is assigned such a task can clearly

visualize the results demanded of him, and may feel at liberty to

employ any one or all of the methods at his disposal.

However, it is not always possible or even desirable to express tasks

in terms of accomplishment.

For example, where the future situation cannot be adequately

visualized, either because of the doubtful values of certain factors

or because of possible changes in circumstances, it may be

impracticable to assign a definite task in terms of accomplishment.

Under such conditions, and sometimes for other proper reasons, it may

be desirable to afford a trusted and competent subordinate a

corresponding measure of freedom of action. In such a case, the

indication of the commander's general objective for his entire force,

together with a directive for action along a certain general line,

without prescription of a definite objective, may be especially

appropriate to the situation. Such is the frequent usage in the issue,

for example, of directives of the type known as letters of instruction

(Chapter VIII).

Again, where immediate response is desired, and where the objective

may be understood by implication, the task may be better expressed in

terms of action, rather than of accomplishment. This is frequently the

case where the task is assigned by word of mouth, by memorandum, or by

signal. In the last-named instance, the signal, when it constitutes a

command fully understood by previous usage or experience, may convey a

practically instantaneous comprehension of the objective. In many such

instances, however, an inferred objective will require more analysis.

The expression of the task in terms of action is frequently desirable,

more especially during an engagement, when tactical considerations are

uppermost. Under such circumstances, two or more objectives may be

suitable to the appropriate effect desired, but their degree of

suitability, and the influence of the factors pertaining to

feasibility and acceptability, may vary rapidly with the course of

events. In such conditions, an order such as "Attack" without

indicating a specific physical objective, may be best calculated to

attain desired results, for the reason, more especially, that it

affords the subordinate a proper freedom of action.

In many cases, the instructions received by a commander will set forth

more than one task, often of varying importance. The proper bearing of

such a double or multiple task upon his future action is set forth,

together with other relevant matters, in the discussion of the

mission, which follows.

On occasion, a higher commander, in assigning a task, may elect to

specify, also, the course of action to be pursued by a subordinate for

the attainment of the assigned objective: for example--

"Deny enemy bases in area ABCD by capturing X Island".

Here the task is to deny the enemy the use of available bases in the

area described; in addition, the higher commander has specified that

this be accomplished by the adoption of a predetermined course of

action (page 88), expressed in the words "by capturing X Island."

Higher authority has in this case made the subordinate's estimate of

the situation for him, and has thus arrived at the decision which the

subordinate would ordinarily reach for himself.

Such procedure may be deemed advisable under certain circumstances:

for example, when time is pressing; when a close control of the

situation is an important factor; when the qualifications of the

subordinate are unknown, as yet doubtful, or known to be inadequate

for the operation in hand; or, for various other reasons which may

suggest themselves according to the nature of the problem.

Occasionally, higher authority, for similar reasons, may also

prescribe the action to be taken, in considerable detail. Examples

occur during operations of unusual complexity, or when the personnel

factors call for special care in coordination of the action.

Sometimes, higher authority, instead of announcing both the task and

the predetermined course of action, may indicate only the latter; in

the example given above, the higher commander would then direct,

"Capture X Island". The directive might also include, in some detail,

the action to be taken to this end.

Procedure such as noted in the foregoing examples involves certain

special considerations from the viewpoint of the subordinate. These

considerations are discussed hereafter (page 96).

The Mission. In our naval service an assigned task, coupled with its

purpose, is known as a mission. As explained previously (page 48), the

purpose indicates the larger aim which is to be served by the

execution of the task. The task indicates the assigned objective,

i.e., what is to be accomplished; the purpose, the further objective

to be served thereby.

The word mission is a derivative of the Latin verb, "to send". Its use

implies the act of sending someone, or of being sent, as an agent for

some special duty, a duty imposed by one in authority. Although an

individual, free to do so, may select his own mission, and thereby

send himself on a special duty, this is not usually the case where an

effective military chain of command exists. Normally the sending

authority is the immediate superior; the agent, the immediate

subordinate.

The mission, once assigned, does not change until it has been

accomplished or until it has been modified or revoked by higher

authority, usually the immediate superior by whom it was assigned.

As previously explained in this connection, the designation of a

purpose, linked with a task, is an essential element of a mission as

treated herein. It is essential to unity of effort that the purpose of

the mission of a commander be common with that of other commanders of

the same echelon who are to participate in the effort enjoined by

their superior's directives. Directives expressed in the Order Form

(page 112 and Chapter VIII) facilitate clear recognition of this

purpose, which appears in the general plan of action prescribed in the

second paragraph of that form. The commander may consider the

relationship thus:

My assigned task is to be accomplished for the purpose of carrying out

my designated part of my immediate superior's general plan.

It is customary to simplify the foregoing to the statement that the

mission is:

(Task) (statement of the assigned task),

(Purpose) in order to assist in the successful execution of (statement

of the superior's general plan).

The words "assist in", etc., may frequently be understood and

therefore omitted.

The foregoing expression of a mission affords, as later explained

(Chapter VI), a method for clear visualization of the effect desired

by higher authority. (See also page 84.)

All of his assigned tasks which materially influence the commander's

Decision (hereinafter discussed) are properly included in his mission;

other tasks, naturally, may be omitted in this connection. In the case

of a double or multiple task (page 86), all the tasks may be related

to a single purpose, or the included tasks may each, or in certain

combinations, be linked separately to appropriate purposes.

Survey of Factors of Fighting Strength. The feasibility and

acceptability of action for the attainment of an objective are

dependent (see the Fundamental Military Principle--page 41) on the

factors of fighting strength. Fighting strength (page 35) is derived

from the means available and opposed, as influenced by the

characteristics of the theater of operations. A survey of these

factors, in proper detail according to the nature of the problem, is

therefore a necessary phase in the process of its solution. Such a

survey completes the basis for the study of courses of action.

Courses of Action. The estimate process naturally takes account (page

80) of methods for attaining the objective indicated in the assigned

task. The military profession has, from time to time, applied a

variety of terms to designate such methods. Terms so used include,

among others, "plans open to us" (or "to the enemy"), "lines of

action", and "courses of action". The last-noted, having been standard

in our naval service for many years, is the term used in this

discussion.

Each course of action is thus a plan of military operations for the

attainment of the assigned objective, and each thus indicates (page

37) "an act or a series of acts" which may be undertaken to that end.

Until a final selection is made for embodiment in the Decision, each

course of action is a tentative solution of the problem. For the

reason given below, a course of action, while under consideration as a

tentative solution of the problem, is also correctly conceived as

indicating an objective and, in proper detail, the action for its

attainment.

When embodied in the Decision, the adopted course of action or

combination of courses becomes the commander's general plan (or the

basis thereof) for the employment of his force; such a general plan

will naturally indicate the commander's general objective (page 49)

and, in proper detail, the action to be taken for its attainment (page

44).

The objective may be specifically stated or may be inferred (see page

82; also page 84 for the corresponding discussion of the expression

of tasks); but, in any event, clear thinking demands that the

objective be definitely envisaged. There is a manifest advantage in

such definite envisaging of the objectives involved in courses of

action. Suitability as to the appropriate effect desired--the first

requirement in the selection of a correct objective (page 51)--is much

more readily tested on this basis. The practical bearing of this fact

becomes apparent during the early stages (Chapter VI) of the process

of solving military problems.

Frequent examples of naval courses of action include (see page 92):

(1) "To destroy the enemy force." Here the objective, "destruction of

the enemy force", is specifically indicated.

(2) "To divert the enemy force." Here also the objective, in this case

"diversion of the enemy force", is specifically indicated.

(3) "To evade the enemy." Here again the objective, "evasion of the

enemy", is specifically indicated.

(4) "To cover friendly and neutral trade." Here the objective,

"protection of friendly and neutral trade by the utilization of

advantageous covering positions", is more or less inferred.

(5) "To escort trade." Here the objective, "protection of trade by

escorting it in convoys", is more or less inferred.

(6) "To patrol the trade routes." Here the objective, e.g.,

"protection of trade by patrolling the trade routes", is inferred.

(7) "To raid." Here the objective, e.g., "infliction of loss and

damage by raiding", is inferred.

In the foregoing instances, the action to be taken is indicated in

general terms. The extent to which the action may properly be

indicated depends on the nature of the problem and is necessarily left

to the judgment of the commander. Two possibilities, between which

there may be various intermediate cases, are as follows:

(a) To destroy the enemy force by simultaneous attacks on

the escort and convoy.

(b) To destroy the enemy force by an attack with the main

force on the escort, following this immediately by an attack

on the convoy with a flanking force before the convoy can

scatter so widely as to make ineffective the pursuit of any of

its units.

For a further application, it will be noted that the national policies

referred to early in this discussion (page 7) are national courses of

action, considered and adopted as methods of attaining national

objectives.

The expression "courses of action", in the sense of a plan considered

or adopted as a solution of the problem, has the defect that it

appears to emphasize the action, rather than the paramount component,

i.e., the objective. So long as this fact is borne in mind, the

limitations of the term "courses of action" need not operate to

influence, adversely, the solution of the problem.

As noted above, the commander brings to mind courses of action by the

mental act of "envisaging", i.e., "viewing with the mind's eye or

conceptionally", "seeing as a mental image", bringing fully and

distinctively to view. How is this done?

Although the time available for the process depends on the particular

problem, the process itself is the same for all. During the

clarification of the problem, the commander will have entertained

certain ideas,--ideas as to such matters as the existing situation,

the desired new situation, the possible physical objectives, the

relative positions and movements of the forces involved, and related

matters. His training and experience cause these ideas to evoke

others, which are associated in his mind with problems of the

past,--in particular, with the bearing of such ideas on the outcome of

those problems.

This process of thinking, if it is to be effective as well as

reflective, requires mental access to certain sources of ideas. These

sources may lie in the study of history, or in the wealth of doctrine

and instructions gathered into official manuals and into other

professional writings, or in the commander's own practical experience.

Logicians who have investigated this natural process point out that

suggested solutions are the resurrection of ideas from past

experience. Good thinking demands access to a large storehouse of

ideas connected in various and flexible ways. The best available

knowledge is the main source from which reflective thinking obtains

relevant and promising suggestions for a solution.

By such resort to analogy, the commander utilizes the accumulations of

past experience. Sometimes he finds that the courses of action thus

suggested are exactly suitable as tentative solutions for his problem.

In other instances, of course, only parts of the present situation are

found to be analogous to those previously encountered. Even then,

however, the similarity of the facts may be helpful in providing

suggestions. Guidance based on limited or partial similarity has been

demonstrated to be better than purely intuitive thinking.

The commander cannot be content, however, to depend wholly on the

guidance of the past. Sometimes, moreover, he may not be able to

obtain suggestions by analogy. New suggestions, ideas not drawn from

past experience, are very desirable; they are possible, also, in the

sense that the result of the analysis of past experience may be

reassembled, in imagination, in novel ways. New courses of action,

overlooked in the past, may be contrived. Original combinations, not

previously entertained, may be devised. Readiness to employ the novel

and the new, as well as to utilize the old, is a prime qualification

for command.

Reflective thinking of this nature requires adequate knowledge of the

capabilities of weapons, so that new possibilities may be perceived as

to coordination in their use. While analogy looks backward to find

applicable lessons, the search for novelty seeks suggestions from

potentialities not heretofore utilized.

The development of the full possibilities of new weapons is an

important source of forward thinking. Such thinking constantly

integrates the current developments in war. The competent commander

does not wait for history to be made; he makes it.

Familiarity with experimentation, research, and new performance is

also a fruitful source of suggestions. When used, this method results

in advance demands by the armed forces for new weapons not yet

supplied.

Closely allied to analogy is the application of ordered and classified

knowledge as to the nature of warfare. Aware of the effects which can

be brought about by the weapons at his disposal, the commander

identifies his objective with one or more of these effects.

The application of ordered and classified knowledge of naval warfare

starts, naturally, with a consideration of its objectives, and

proceeds thereafter to the study of the various classes of operations

which may be utilized to this end. Naval effort has as its objective

the keeping open of sea communications (see page 62). Command of the

sea exists for one belligerent when he possesses and can exercise the

ability to move surface traffic, while also being able to prevent the

enemy from doing so.

Naval warfare, therefore, logically includes operations for the

purpose of gaining, maintaining, or disputing command of sea areas,

especially under conditions where freedom of movement and the keeping

open of sea communications are of vital importance.

Such operations may be classified under the headings:

(1) For securing command of sea areas,

(2) In sea areas not under command, and

(3) In sea areas under command.

On the basis of this classification, specific operations, broadly

considered, appear to be limited in number. As to classification (1),

applicable operations are: to destroy the enemy naval forces, to

contain them, or to divert them. For (2), applicable operations are:

to raid, to make war against enemy trade, to attack or defend naval

lines of communication, and to conduct amphibious warfare requiring

overseas movement. For (3), applicable operations are: to blockade

trade, to defend own coastal and critical areas, to safeguard

expeditions against enemy territory, and to carry out offensive

operations against enemy coastal objectives.

Manifestly, each such operation, broadly viewed, may be considered, in

an estimate of the situation, as a course of action. Each such course

of action (or operation) will involve, if developed into a more or

less complete plan of action, numerous detailed operations which

constitute parts of the whole. (See page 37.)

There can be no rigid line of demarcation, always applicable, between

courses of action and the more detailed operations pertaining thereto.

For example, "to raid" may be, in one instance, an operation of such a

character, from the viewpoint of the commander, as to be envisaged,

correlatively with "to destroy", as one of his courses of action. Yet,

in another problem, a raid may be visualized, properly, as a detailed

operation pertaining, in a subordinate capacity, to a more

comprehensive operation envisaged as a course of action "to destroy".

Similarly, what is a broad course of action from the viewpoint of one

echelon in the chain of command, may be correctly viewed, on a higher

echelon, as a detailed operation. Operations assigned in tasks imposed

by higher authority become the basis for the determination of courses

of action on the next lower echelon, a procedure which continues

throughout the chain of command until specialized, on the lowest

echelons, in the form of a simplified routine (see page 84).

While the list of courses of action given above is made up from the

viewpoint of broad strategical problems, a similar list can be

assembled for other problems. For example, the order, "Destroy enemy

naval forces", if taken as the motivating task of a tactical

estimate, will be the basis for certain courses of action,

constituting, when complete (see below), a well-recognized general

plan for a naval battle. This plan will in turn call for various

detailed operations on the part of the several subdivisions of the

force under the commander who makes the estimate (see page 95).

As a tentative solution of the problem a course of action may be

complete or partial, i.e., it may, if carried out, provide for the

complete attainment of the objective; or, such complete attainment may

require a combination of several of the courses of action under study.

The exclusive consideration of courses of action of the complete type

possesses the advantage of minimizing the total number of solutions

under study. This simplifies the procedure of analysis and of

comparing courses of action with each other, because of the relatively

small number of courses to be tested and to be compared.

However, it is frequently difficult, and sometimes impossible, to

visualize complete courses of action, especially during the early

stages of the estimate. Sometimes the initial visualization of partial

courses and their eventual combination into a complete solution will

be found necessary.

Therefore, either or both of the foregoing systems of formulating

courses of action may be found appropriate, according to individual

preference and the nature of the particular problem.

Individuals, comparable with respect to knowledge, appear to vary

greatly in their ability to produce the appropriate suggestion, as to

courses of action, at the right time. The reason for this phenomenon

is not altogether clear, but it is known that thinking seems to be

limited not merely by the range of knowledge, but by whatever part of

it becomes available when needed. This point invites attention to

another procedure which is open to the commander with respect to

stimulating reflective thinking. This procedure recognizes the fact

that, when two or more minds attack a problem, together, the combined

effort often increases the applied mental power. This fact is

universally recognized, for example, in the utilization of staff

assistance (page 13).

Inherent and acquired ability have unquestionably much to do with the

possibilities of visualizing single courses of action with respect to

their completeness as to attainment of the objective. One method of

visualization seems to be the mental picturization of more or less

detailed operations, followed by their combination, through rapid

synthesis, into complete courses of action.

An example of this method would occur where several rather specific

operations were visualized, involving seizure of certain localities as

a defensive measure. If it were then observed that the objective in

each such case was "denial to the enemy of a particular naval-base

site in the area ABCD", an appropriate expression of a comprehensive

course of action would be "to deny the enemy naval-base sites in the

area ABCD".

Another method of visualizing appropriate courses of action seems to

involve initial recognition, in the first instance, of such courses as

broad and comprehensive general plans, without first visualizing and

combining their details. This method appears to be more usual after

considerable experience or training. It is therefore possible that

this second method is merely a practiced development of the first, the

process of synthesis being so rapidly accomplished that it becomes

subconscious.

The nature of the particular problem has also an unquestioned bearing

on this subject. In instances where no single course of action can be

found which is adequately expressive of complete attainment of the

objective, the final selection of a method of attaining the objective

will necessarily be through a combination of the courses of action

under study (page 93).

For example, if the assigned task were to "protect trade in sea area

ABCD", the extent of the area, together with its geographical position

relative to locations from which enemy attacks could be launched,

might not be such as to permit the attainment of the objective by a

single course of action such as "to escort trade in convoys" or "to

patrol the trade routes". Both of these courses of action might be

necessary, and, in addition, perhaps, the further course "to cover

focal points M and N".

Each of these courses of action has, as its objective, the

establishment of a protected area or areas, stationary or moving, for

the safe passage of merchant vessels. However, for purposes of

expressing the course of action involved, the contemplated procedure

is in this case better indicated by a combination expressed in terms

of action, the objective being inferred as a matter of mutual

understanding. The less particularized expression of the course of

action in terms of the objective would, in this instance, convey a

less definite idea of the procedure under consideration.

Similar considerations pertain frequently to naval problems, more

especially to those involving naval engagements of considerable scope.

The solution of such a problem takes, typically, the form of an

operation consisting, not of a single "act", but of "a series of

acts", i.e., of a number of stages or phases of battle, each being a

preparation for the one following, until the final stage provides for

the attainment of the assigned objective.

For example, a first consideration might be "to reduce enemy carrier

aircraft strength by" certain pertinent operations. A second

consideration might be "to reduce enemy battle-line speed by" certain

operations in order to force the enemy to accept battle. A third might

be "to reduce enemy battle-line speed, life, and hitting power by

gunfire" within certain range bands, in order to exploit own strength

and enemy weakness at those ranges. A fourth might be "to continue

reduction of enemy battle-line strength by gunfire, closing to" such a

range as is suitable to that end. Finally, a fifth consideration might

be "to inflict conclusive damage on enemy battle-line with torpedoes".

All of the foregoing partial courses (other possibilities having been

studied and discarded) might then be combined into one operation as

the selected course of action "in order to destroy the enemy

battleship strength",--such destruction being the assigned objective.

The degree of detail in which a course of action may be visualized for

purposes of the estimate will vary with the same factors, i.e.,

personal facility and the nature of the problem. Practice in the

solution of problems appears to develop such facility that entire

plans can be visualized as courses of action, each plan reasonably

complete as to details with reference to physical objectives, relative

positions, apportionment of fighting strength, and provision for

freedom of action. However, it is rarely, if ever, necessary to

visualize courses of action minutely in an estimate of a basic

problem; the extent to which they are viewed mentally, as detailed

plans, need only be such as to fulfill the requirements of the

particular problem (see Section I of Chapter IV).

The statement of a course of action, for purposes of the estimate,

will naturally be along broad and comprehensive lines, although some

important matters of detail (relatively speaking) may be added if this

is found desirable as the estimate proceeds. It is with these

considerations in mind that the standard practice has been developed

of formulating courses of action, while under study as tentative

solutions of the problem, in broad terms, appropriate to general plans

of action.

The commander may find, on occasion, what appears, on first

examination, to be an exception to the rule, herein treated as valid,

that a course of action, correctly conceived, always contains the two

elements (1) objective, specific or inferred, and (2) action for its

attainment. However, apparent exceptions to this principle are due to

special conditions which, on proper analysis, reveal no actual

exceptions. Certain examples, now to be discussed, demonstrate this

fact.

For instance, when the higher commander deems such procedure advisable

(page 86), he may make his subordinate's estimate of the situation, as

well as his own, and may accordingly indicate both a task and a

predetermined course of action for the subordinate to pursue: for

example:

"Deny enemy base sites in area ABCD by capturing X Island."

In such a case the higher commander has indicated the predetermined

course of action in the words "by capturing X Island". This expression

indicates a specific objective, the capture of X Island. The

expression also indicates, though not in any detail, the action to be

taken, i.e., it specifies "capture", rather than "occupation",

"isolation", or some other form of control (page 8). Any further

development of the action is left for the subordinate to determine.

The procedure to be followed by the subordinate commander in solving

such a problem is described hereafter (page 102) in the discussion of

the analysis of courses of action. In any event, it is manifest that

there is here no exception to the rule that a course of action,

correctly conceived, contains the two elements of objective and action

for its attainment.

A further example may occur when the higher commander, instead of

indicating both the task and the predetermined course of action,

indicates only the latter (page 86), by directing "Capture X Island".

Once the subordinate has recognized this directive as containing a

predetermined course of action, but not a normal task, he realizes

that the objective so indicated would ordinarily be left for him to

select. He also realizes that the action to be taken for its

attainment is left for him to determine, in further detail.

In this case, then, what is really a predetermined course of action

appears in the guise of a task. When the commander, receiving the

directive, has recognized this fact, he proceeds in the manner

hereafter indicated (page 103) in the discussion of the analysis of

courses of action.

In any event, it is manifest that here, also, there is no exception

to the rule that a course of action, correctly conceived, contains the

two elements of objective and action for its attainment.

In such a case as the foregoing, how does the commander recognize that

the apparent task is really a predetermined course of action? He could

easily go astray because the directive, until analyzed, appears to

contain a normal task. The directive indicates an objective, thereby

resembling a task. The directive will usually indicate, at least in

some degree, the action which the subordinate is to take. Hence, so

far as superficial appearance is concerned, the subordinate commander

may easily mistake the predetermined course of action for a normal

task. However, he discovers the difference when he endeavors to find

courses of action which are appropriate to this apparent task.

The commander will then discover that, while he can visualize actions

whose accomplishment will attain the objective indicated in the

apparent task, he cannot visualize any objective completely suitable

to the case (page 93), intermediate between the assigned objective and

the indicated action. He can state the assigned objective in other

words and adopt such a statement as an expression of his general

objective, but the two objectives, the one he selects and the assigned

one, will really be identical.

This inability to visualize an objective of the commander's own

selection, suitable to the case, is inevitable, because higher

authority has already done this for him. He may find it advisable to

develop further the action needed for the attainment of the indicated

objective. On occasion this, also, will have been predetermined by the

higher commander.

The foregoing considerations have been given special emphasis and

deserve careful study, because an appreciation of these facts is

necessary to a true understanding of the nature of correctly conceived

courses of action.

Analysis and Selection of Courses of Action. After one or more courses

of action have been determined as tentative solutions of his problem,

the commander will be confronted with the necessity of deciding upon

that course of action, or combination of courses of action, which will

best attain the assigned objective, i.e., be the best way out of the

seeming difficulty. The analysis, in each case, will settle

suitability on the basis of the appropriate effect desired,

feasibility on the basis of relative fighting strength as established

by a survey of means available and opposed, influenced by the

characteristics of the theater, and acceptability on the basis of

consequences as to costs.

In connection with these considerations, the detailed operations

involved in each course will be analyzed so far as may be necessary

(page 95) and with respect to correct physical objectives,

advantageous relative positions, proper apportionment of fighting

strength, and adequate freedom of action (see the Fundamental Military

Principle--page 41). A selection shown to be best, from the standpoint

of suitability, feasibility, and acceptability of the consequences,

will be adopted as the decision.

The tests of courses of action to determine whether they fulfill the

requirements of suitability, of feasibility, and of acceptability as

to consequences take account of the usual included determinants as

listed and explained below. The list is not rigid, and the commander,

according to the nature of his problem, may desire to omit certain of

the items or to include any other considerations which may be

applicable.

With respect to suitability, the commander considers the following:

(1) General. The test for suitability (see also page 31)

calls for conformity as to both the nature and the scope of

the motivating task. With respect to conformity in nature,

the test leads to a conclusion as to whether the course of

action, if carried out successfully, will or will not

contribute to the accomplishment of the task. As to scope,

the test leads to a conclusion as to whether the course of

action, if carried out successfully, will or will not

accomplish the task in full; and, if not in full, to what

extent. The factor of urgency is also considered here.

It is frequently possible for the commander, merely by

concentrating his thought on this particular perplexity, to

conclude at once that the course of action is suitable. In

other cases, a considerable amount of study may be needed.

This analytical study consists in breaking down the course of

action into its component parts, i.e., the detailed operations

which naturally grow out of it. This procedure is similar to

that described later (Chapter VII), with respect to

formulating a plan, but during the basic estimate the

procedure, when utilized, is for a different reason--solely

that of assisting in the analysis.

(2) Details, (a) Conformity as to nature. Will the course of

action, if successfully carried out, contribute, at least in

some degree, to the accomplishment of the task? If not, such a

course is rejected. Courses that do contribute, however, are

not rejected until the possibilities of combination have been

examined, later.

(b) Completeness. If the course of action is successfully

carried out, will it accomplish in full the motivating task?

If not, how much will it contribute towards such

accomplishment? With what other courses of action can it be

combined, to accomplish the motivating task in full? With what

others can it be combined to accomplish the motivating task in

part, and in such case how nearly does the combination

contribute to full accomplishment?

This examination may lead to combinations of certain partial

solutions.

(c) Desirability as to Urgency. The commander now considers

the element of time. Complete accomplishment of the motivating

task within his own theater may come too late to meet the

requirements of the common effort of the entire force.

Synchronization with the action of other task-group commanders

may be so important that timing becomes vital. As to this

consideration, two courses of action, equally competent, may

differ greatly in their qualification relating to urgency; one

may be found highly desirable and the other completely

unsatisfactory.

As to feasibility, the commander considers the following:

(1) General. The test for feasibility (see page 31) is

concerned with whether the course of action is practicable.

Has it reasonable chances of success under the particular

circumstances? Are the difficulties surmountable? Is it

easily practicable, practicable with some difficulty, or very

difficult?

The commander, if he concludes that the course of action is

not a practicable one, rejects it from further consideration

in the estimate of the situation. However, care is taken at

this point not to dismiss, abruptly, courses of action which

may later be combined advantageously with one or more others.

Here, again, as noted for the suitability test, the commander

may sometimes profitably analyze the course of action by

breaking it down into more detailed operations.

As a result of the tests discussed above, the commander is

able to make a list of courses of action upon which his

confirmed judgment has bestowed the qualities of suitability

and feasibility.

He is also able to take stock to see how many of the solutions

are complete, how many are incomplete, and in the latter case

to what extent they constitute partial solutions. It is, of

course, desirable to have as many complete solutions as

possible, and at this point it may be possible to merge two or

more incomplete solutions into a single course of action which

better fulfills the test of suitability. The commander can

also take stock, similarly, of the degree of feasibility,

already referred to, as to the retained courses of action.

(2) Details, (a) Prospects of Success. Here the several courses

of action are considered relatively, with respect to the chance

of success in each. In the rating of courses on this basis,

the commander excludes consideration of losses except as they

may influence success or failure. He notes, however, his

considered expectations as to losses. Losses may appear to be

so great that success is doubtful. Certain courses of action

may be particularly vulnerable to enemy opposition because of

the types of weapons involved or because of favorable enemy

positions. Choice of such a course would permit the enemy an

initial advantage.

(b) Facility of Execution. This subject has to do with the

relative ease or difficulty of carrying out the several

courses of action. On the basis of the existing situation,

each course of action may be compared with all the others to

determine their relative merits with regard to the facility of

execution. Consideration is given to the action involved

against the several physical objectives; to the movements

needed in making new dispositions; to the relative adequacy of

the forces as to numbers and types of weapons; and to the

measures required for freedom of action.

A review of the previous discussion of these elements (Chapter

IV) may be very helpful in connection with this comparison. As

to freedom of action, for example, the commander may ask

himself which course is best from the standpoint of using the

initiative to advantage; and which course of action lends

itself best to the advantageous use of surprise. As the

commander reflects on these matters, other similar questions

may be suggested.

(c) Utilization of Own Strength and Exploitation of Enemy

Weakness. In his original visualization of each course of

action, the commander has naturally considered how to utilize

his own strength to best advantage, and how best to exploit

enemy weakness. In fact, especially in a detailed tactical

estimate, these considerations may have been predominant in

envisaging the courses of action. A careful evaluation of the

merits of each course of action in this respect is accordingly

necessary before a choice is made.

With regard to acceptability of consequences as to costs, the

commander considers the following:

(1) General. The process of putting a course of action to

proof as a tentative solution of the problem remains

incomplete until the course has been tested to determine its

consequences as to costs, so far as these can be visualized

in advance. The process involves an evaluation of the

diminution in total advantage which will result in the event

of failure, and a comparison of gains with losses in the

event of success. The situation to be expected, if the course

of action is carried out, is visualized in order to determine

the future effect on the creation or maintenance of an

ultimately favorable military situation.

In testing each course of action for acceptability as to its

consequences (page 31), the commander considers the cost of

success, the cost of failure, and the possible gain and loss

in perspective with the united effort as a whole. Questions

which he may pose include: If the course of action is

successful, will the costs be so prohibitive as to adversely

affect the successful accomplishment of the further effort? If

a tactical situation is under consideration, will the costs

prevent the accomplishment of the strategical aim? If the

course of action fails, what will be its effect? Will it cause

the entire plan to fail? Will its failure affect, for example,

the national morale?

If the command--and ultimately the State--can afford the

losses and other disadvantages which will be incurred as a

result of either the success or the failure of the

contemplated effort, a course of action may be considered as

acceptable from the standpoint of consequences as to costs.

As previously noted with respect to suitability, it may be

desirable to consider, with regard to consequences, the

detailed operations which may be involved in each course of

action.

Courses of action involving excessive consequences as to costs

are rejected. Notation is made of the relative degree of

acceptability, with respect to consequences as to costs, of

those courses of action which are retained.

(2) Details. (a) The Results of Success and of Failure. Each

course of action is examined to visualize the situation which

would be brought about for the commander and for the enemy in

case of success or of failure. The relative possibilities of

recovery toward a more favorable situation are weighed. This

consideration involves relative risks, for it may be that a

certain course, otherwise satisfactory, might entail

intolerable conditions should failure ensue.

The costs are measured in terms of fighting strength. It has

to be considered whether the sacrifices involved are worth the

gains which will follow; whether the objectives if attained

will be sufficiently valuable when the need of fighting

strength to accomplish further aims is considered.

(b) Comparison of gains and costs. When costs are found to be

in excess of the over-all gains, this fact may be the basis

for rejecting any courses of action which are less desirable

than others. However, retention of a course found to be costly

may be justified for sound reasons.

* * * * *

When, as in the example given previously (page 96), the commander

receives a directive such as "Deny enemy base sites in the area ABCD

by capturing X Island", he carries through his estimate of the

situation in the usual manner. He notes, however, that the capture of

X Island has been indicated as a predetermined course of action. He

makes a proper survey of the factors of relative fighting strength. He

considers all pertinent courses of action. He goes through this

procedure in order to reach an understanding of all the elements of

his problem. He wishes to understand the necessary background. He

realizes the importance of a grasp of the considerations which have

led higher authority to arrive at the predetermined course of action.

By carrying through the usual estimate procedure, including the

analysis of all pertinent courses of action, he assists himself to

arrive at a proper concept of the action to be taken to capture X

island. In this way he establishes a sound basis for formulating a

detailed plan (in the second step), for inaugurating planned action

(in the third step), and for supervising this action (in the fourth

step). He also establishes a basis for any constructive

representations which he finds it advisable to make to higher

authority (page 15).

In another example previously given (page 96), the higher commander

indicates only the predetermined course of action (by a directive

"Capture X Island") and omits the statement of the true underlying

task. The subordinate, on discovering this fact, deduces the

underlying task and carries through the estimate procedure, modified,

as explained for the previous example. In addition to the merits as

previously stated, this method has a further advantage. The deduction

of the underlying task enables the commander to judge whether any

advisable or necessary deviation or departure from the predetermined

course of action (page 15) involves merely a variation from the letter

of his instructions or, more important, from their spirit.

For instance, the directive, as in the case previously discussed, may

have been "Capture X Island". The higher commander when issuing this

order, may have stated his own general plan to be "This force will

protect the base at A." The commander, on receipt of this directive,

then deduces his true task. This is "Deny enemy bases in area ABCD"

("by capturing X Island"--a predetermined course of action), the

purpose of the mission being "in order to protect the base at A".

Now it may be found that the enemy, unconcerned as to X Island, is

moving to reinforce Y Island and to use it as a base to attack the

base at A. The commander then properly decides to capture Y Island,

instead of X Island. By his identification of the predetermined course

of action as such, and by his correct deduction of the true underlying

task, the commander has established a sound basis for the solution of

his problem. He can now, with confidence, defer or abandon the capture

of X Island, and can devote his efforts to the capture of Y Island.

His confidence is justified because he knows his decision to be in

accordance with the spirit of his instructions.

Naturally, if the higher commander directed, "This force will protect

the base at A----", and added, later in his directive, "Deny enemy

base sites in area ABCD by capturing X Island", the subordinate

commander's deductions would have been made more easily.

* * * * *

The full play of the reasoning power is called for in the process of

visualizing courses of action and of selecting the best. This process

is the crux of the first step. Here the knowledge of the relationship

between cause and effect is applied. Here, also, the commander is

brought fully to realize that, to reach a sound decision, there is a

requirement for a studied development of each stage by which the human

mind passes from recognition of a necessity for action to the ultimate

conviction as to the best course to pursue.

As essential background for the utilization of his intellectual powers

in this process, the commander requires knowledge of the capabilities

and limitations of the technique of his profession and of the weapons

of his calling. To the necessary knowledge gained through his own

experience, either in actual warfare or in peacetime exercises

simulating this experience, he adds the equally essential familiarity

with the science of war, and with the lessons to be drawn from

historical instances of success and failure. In effect, it is here

brought home to him that, on a fundamental basis of earnest thought,

mental ability, character, knowledge, and experience, finally rests

the soundness of decision (see page 219).

The Decision. The word "decision" has the primary meaning of a

conclusion. A decision (conclusion) is essential as a starting point

for further procedure. Sound decision is the essential preliminary to

wise planning and effective action.

The range within which military decisions may fall extends from the

instantaneous resolve to meet an emergency, to the conditional

intentions of a distant future. Within this range will be found many

decisions which the commander is necessarily called upon to reach

during the four steps toward the attainment of an assigned objective.

The course of action, or the combination of courses, as finally

selected by the commander upon the termination of the first step,

represents his conclusion as to his outlined plan for the attainment

of his assigned objective. This conclusion will indicate, specifically

or inferentially, his general objective, as selected by himself,

and--in proper detail--the action required for its attainment. (See

pages 88 and 95). The conclusion is thus his Decision, which provides

the general plan, or the basis therefor, from which he will, in the

second step, develop a detailed plan of operations for his force.

Illustration of the foregoing process may profitably be initiated with

respect to the highest echelon involved in the case of a State. The

primary national objective of organized government (Chapter I, page 7)

is the ensurance of envisaged prosperity and of essential security for

the social system which is the fundamental basis of the community.

This aim, as embodied in basic policy (see pages 8 and 9), is the

objective visualized by the people of the State, or by its

policy-forming elements, in the capacity of an organized government.

For the maintenance of the condition represented in this policy, or

for the creation of such a condition not already existing, an

appropriate task of the State, as the political embodiment of the

national will, might be to maintain or establish friendly (at least,

not hostile) governments and social systems in those key localities of

the world whence, otherwise, effective threats may arise.

The national mission (the mission of the State) then becomes:--

(Task) To maintain or establish friendly (at least, not

hostile) governments and social systems In those key

localities of the world whence, otherwise, effective

threats may arise,

(Purpose) in order to ensure envisaged prosperity and

essential security for the social system which is the

fundamental basis of the community.

A national estimate of the situation, by the highest authority of the

State, to determine the effect to be attained for the accomplishment

of the foregoing mission, takes account of the possibilities of

accomplishment through psychological, political, economic, or military

pressure, or by combinations thereof. As a result of this accounting,

the State adopts a national Decision which indicates the best way of

accomplishing its mission.

To carry out this Decision, each of the primary subdivisions of the

State's organization is assigned a specific task or tasks, whose total

effect is designed to achieve the result embodied in the national

Decision. The task of each such primary subdivision is linked to a

purpose which is the attainment of the objective indicated in the

national Decision.

In like manner, each organization of the national armed forces is

governed in its action by a task assigned to it as a result of a

Decision made by the proper authority on the next higher echelon. Each

commander is thus provided with a mission which consists of an

assigned task and of a purpose as indicated by the general objective

decided upon by his immediate superior.

The Second Step

The second step, that of resolving the required action into detailed

military operations, may now be undertaken unless the Decision reached

in the first step is intended for future reference only. During the

second step the commander, if he carries the procedure through to its

logical end, visualizes his proposed operations as tasks, in order to

ensure their proper formulation. He may, if it is his intent to issue

a directive or directives for the execution of his plan of operation,

or a part thereof, arrange his procedure so as to facilitate the third

step.

The common characteristic of problems of the second step is that they

deal with matters pertaining to the support of the action decided upon

in the first step, and that they are properly problems for the

commander who made that Decision, and not for his subordinates, to

solve. Such problems are appropriately termed subsidiary problems.

Their full solution involves subsidiary estimates, subsidiary

decisions, and, not infrequently, distinct subsidiary plans and

subsidiary directives.

Each detailed operation derived, during the second step, from the

outlined plan of operations (as embodied in the basic Decision) is

determined upon the basis of an estimate procedure essentially similar

to the basic estimate. There is thus a series of subsidiary estimates

for this purpose. Such estimates tend to be abbreviated and informal,

since the necessary data, and often much of the consideration as to

the subsidiary courses of action, may be available from the basic

estimate.

Unless the detailed operations are of such a character as to require

development into subsidiary plans as a basis for subsidiary

directives, such operations are merely embodied, in the form of tasks

or otherwise as may be appropriate, in the basic plan. In the excepted

cases, where subsidiary plans, in detailed form, are necessary or

desirable, such a plan may be the result of a more formal and

specialized subsidiary estimate.

Chapter VII is devoted to a discussion of the second step.

* * * * *

The problem involved in the first step has been conveniently termed

the basic problem because it is directly concerned with the attainment

of the assigned objective (page 81). The solution of the basic problem

in the first step, and of its corollary in the second step, completes

the planning stage.

The Third Step

The third step consists of the formulation, and--if appropriate--the

issue, of the directives which convey to the subordinate the will and

intent of the commander. From the mental standpoint, the third step

begins when the commander forms the intent of immediately promulgating

his directives for the execution of the planned action. Whether or not

the third step is partially combined with the second, its problem is a

separate one. Its complete solution inaugurates the action planned in

the second step.

The third step is discussed and developed in Chapter VIII.

The Fourth Step

The fourth step, which calls for mental effort in the solution of the

problem of supervising the action, requires a constant, close

observation of the unfolding of the original situation. The procedure

employed is customarily termed The Running Estimate of the Situation.

Only an alert commander can invariably determine whether the situation

is unfolding along the lines desired by him, as promulgated in the

directives of the third step. In effect, the commander, after action

is begun, considers the changing situation as a variable in the

problem presented for his solution by the original (basic) situation.

With the march of events, he is, therefore, constantly critical to

detect whether variations from the original situation are in

accordance with his design or whether these variations have introduced

new incentives which demand modification or alteration of his plan, or

its complete abandonment.

The fourth step is discussed and developed in Chapter IX.

Sequence of Events in the Four Steps

When all of the elements of the entire procedure of the four steps are

present, they take, from the viewpoint of the same commander

throughout, the following form:

(1) First step: The commander, confronted with a strategical situation

(page 83), makes a strategical estimate and comes to a strategical

Decision. The problem, the estimate, and the Decision are basic.

(2) Second step: The commander now is confronted with a particular

problem, one proceeding from his basic problem and involving the

details of a plan of execution to carry out the Decision reached in

the first step; this problem consists, itself, of numerous other

problems of detail, which require solution by the commander himself.

The basic Decision has embodied an outlined plan, strategical in

nature, for an operation to accomplish the motivating task of the

first step. This plan requires resolution into the detailed operations

necessary for its full accomplishment.

Each such detailed operation, as part of the outlined plan embodied in

the strategical Decision, calls for a proper estimate. Though usually

not formal in nature, more especially if the necessary data can be

found in the basic estimate, such estimates are fundamentally the same

as for the basic problem. The assembly of such detailed operations

results in the formulation of a basic plan.

At this point, additional problems may present themselves, these being

frequently tactical in nature. Such, for example, may be sortie plans,

approach plans, and Battle Plans. Other specialized plans (training,

intelligence, logistics, etc.) may be needed. The data essential for

the solution of such problems are more detailed than for the usual

strategical basic problem. In some instances, such subsidiary plans

may be developed directly from the basic Decision by procedures

distinctive of the second step. In other instances, solution may

require an additional subsidiary estimate, along the lines typical of

the first step. These subsidiary estimates lead to subsidiary

decisions, which in turn require to be resolved into the necessary

detailed operations.

(3) Third step: In the third step, the directives, if the basic

problem was strategical in nature, will be of a strategical character.

However, if subsidiary tactical problems were also involved, tactical

directives will frequently be included. Logistics directives and other

specialized instructions may also be a feature.

(4) Fourth step: The supervision of the planned action, in the fourth

step, may involve a new strategical problem, perhaps several. In such

event each new basic problem will initiate a new series of problems,

with corresponding directives, as described above. Changes in

strategical plans may be called for. If no strategical changes are

involved, there may nevertheless be introduced one or more new

tactical or logistics problems, with corresponding changes in the

subsequent procedure. The fourth step may, however, merely involve

changes in supporting plans (tactical, logistics, etc.), with

resultant changes in the directives involved. Finally, the fourth step

may involve changes, for clarification, in the directives formulated

in the third step.

Variations in the foregoing procedure are frequent. The most usual is

perhaps the case where the commander, receiving a tactical (instead of

a strategical) mission, solves such a tactical problem as a basic

problem in the first step; resolves his Decision into detailed

tactical operations in the second step; issues a tactical directive or

directives in the third step; and supervises his planned tactical

action in the fourth step.

Phraseology as to "Course of Action", "Operation", and "Task". It is

important to avoid the possibility of becoming confused because each

of the terms "a course of action", "an operation", and "a task", is

correctly visualized as "an act or a series of acts". In the first

step, the selected course of action (see page 104) indicates the "act

or series of acts" decided upon as representing, in general terms, an

effort for attainment of a specified objective and is therefore stated

as a comprehensive method of attaining that objective. The Decision

thus adopts this course of action as a general plan of operations, or

as a basis therefor.

In the second step, the required action is developed to place it upon

a practical, workable basis as a detailed plan to be executed. The

"act or series of acts" represented by the selected "course of action"

has now become a detailed "act or series of acts". As such, it is now

susceptible of being assigned, in whole or in part, to subordinate

commanders as "tasks". The cycle within that particular echelon is

completed when the tasks are thus assigned. The commander has thereby

charged his immediate subordinates with the commission of specific

"acts or series of acts".

Each such subordinate commander necessarily decides on the best method

of accomplishing his assigned task, i.e., on the course of action (act

or series of acts) which will best accomplish the effort required of

him. The procedure (for each commander on that echelon) thus begins

anew until an echelon is reached where the character of the required

action has already been determined as a matter of routine (see page

84).

The Use of a Form in the Solution of Problems

The natural mental processes (see page 19) are employed in all of the

four steps. The processes, in each step, require modification to an

extent dependent upon the factors to be evaluated.

A form has been adopted for the application of the mental processes in

the first step. This form, long known to the military profession as

The outline of The Estimate of The Situation (see Appendix), sets

forth in a logical manner and order the several considerations likely

to influence the selection of correct military objectives in problems

of wide, as well as of lesser, scope. The use of this form is

conducive to uniformity of reasoning. It centers the attention upon

essentials, in order to ensure that no material factor bearing on the

solution of the problem is overlooked. It guides thought along a

specific path and, through the influence of suggestion, deliberately

increases the expenditure of mental effort.

The procedure indicated in the form contributes to the Decision

reached as a result of an Estimate of the Situation, only to the

extent that it provides an outline for, and encouragement of,

systematic analysis and reasoning.

To prove successful in stimulating rather than stifling creative

thought, flexibility is a characteristic of any form capable of

application in such dissimilar circumstances as may be presented by

the varying scope of military problems. The Estimate Form is such a

flexible guide. If a commander, in solving a problem, feels the need

of greater flexibility, he may, of course, modify or adapt the form to

his particular needs. In so doing, however, he bears in mind that

departure from orderly processes of reasoning, on which the form is

based, tends, through possible neglect of fundamental considerations,

to lead to the omission of essential features of the analysis.

On the other hand, a rigid following of the form may frequently cause

much repetition. This may be avoided, unless desired for emphasis or

other appropriate reasons, by reference back to preceding portions of

the estimate. It is also to be noted, however, that the Estimate Form

is adapted to a progressive procedure. Very frequently the earlier

consideration of some aspect of the problem can later be expanded both

in scope and in proper detail by reason of additional information

which has become available during the intervening stages of the

procedure.

The distinction between certain strategical and tactical problems

(page 83) may introduce variations in the handling of the Estimate

Form, and may affect the weight to be given the various factors. The

use of the Estimate Form, as described in Chapter VI, applies in full

to problems which embrace the complete scope of broad strategical

concepts. It is suitable also for problems of limited scope, for which

certain modifications or abbreviations are required. When applied to

problems of a detailed tactical nature, the emphasis on the factors of

fighting strength is somewhat different from that for strategical

problems. For certain subsidiary problems (page 106), the Form may be

closely applicable or may require considerable adaptation. In no case

is it difficult to modify the Form to suit the requirements of the

problem.

An estimate of a relatively broad strategical situation may normally

be reduced to writing, because time is usually available. On the other

hand, an estimate of a localized tactical situation frequently

requires almost instantaneous decision. Except in the preparation of

plans to meet contingencies, such an estimate can rarely be given the

elaborate form frequent in estimates of situations which are broadly

strategical in nature. When such tactical plans are prepared well in

advance of the event, the commander bases the estimate upon various

assumptions as to the circumstances of a probable situation.

The written solution of tactical situations under various assumptions

is a valuable feature of training to this end.

During the second step, i.e., the resolution of the action, as

embodied in the Decision, into the detailed operations required, the

method considered most helpful is to arrange the procedure on the

basis of the salient features of a military operation (page 39 and

Section III of Chapter IV). This procedure facilitates not only the

determination of the necessary operations, but also the later

formulation of directives.

The second step, like the first, makes use of the estimate procedure.

This is inevitable, in view of the fact that the mental processes are

identical (page 106) for the solution of the problem of both steps.

The application of the estimate procedure to the second step may be

tested, aside from the logic of the theory involved, by careful

analysis of examples. For instance, if the basic Decision was to

determine the location of enemy forces in the area ABCD, this becomes

the basis for a plan embodying the best method of determining the

location of such enemy forces (an operation, or a series of

operations). One method of procedure (course of action) to achieve

this objective may be to search the area by aircraft; another may

involve a search by cruisers; another by destroyers; another by

submarines; etc. The operation or operations finally determined upon

may be any one of these, or a combination of two or more of them,

perhaps of all of them. The fundamental procedure leading to this

conclusion is identical with that of the basic estimate.

There are a number of possible variations of the fundamental mental

processes applicable to the second step, according to the facility and

the preference of the commander. Practice seems to develop such

facility (see also page 94) that entire plans, each properly

integrated with respect to physical objectives, relative positions,

apportionment of fighting strength, and freedom of action, may be

visualized separately from each other.

At the other extreme, the elementary procedure is to utilize these

salient features of such a plan, successively, to suggest detailed

operations. The features after the first are then used either to adapt

or to complete the operations suggested by preceding features, or to

suggest new operations. This elementary procedure, being the simpler

and more methodical of the two, is the one explained hereafter

(Chapter VII).

However, there are various possibilities as to procedures intermediate

between these extremes. One such procedure would visualize operations

primarily on the basis of correct physical objectives, adapting and

completing such operations by reference to the other features; the

procedure would then utilize relative positions, etc., to suggest

additional operations, which in turn may be similarly adapted or

completed. The commander is of course at liberty to use the procedure

best suited to his own working methods and to the particular

situation; naturally, he bears full responsibility for any errors due

to a faulty choice of procedure.

From the standpoint of the exercise of mental power in the solution of

military problems, the second step may be taken to include the

assembly of the commander's conclusions in the form of directives. The

third step begins, however (page 107), when the commander forms the

intent of immediately promulgating such directives.

The third step makes use of the Order Form. In our naval service, this

form is applicable, with certain modifications, to all written

directives pertaining to operations other than routine. The subject

matter is presented in a logical sequence which experience has shown

to be effective. The Order Form assists in the solution of the problem

by providing a comprehensive vehicle with which all echelons are

familiar.

In the fourth step, i.e., the supervision of the planned action, the

prime essential is the maintenance by the commander of a Running

Estimate (page 107). For this purpose there is a definite technique of

which the Estimate Form provides the basis, and by means of which the

solution of this important problem is aided.

Conclusion As To the Approach to the Solution of Military Problems

The foregoing considerations indicate that planned attainment of a

military objective requires the application of mental effort in four

distinct steps.

The sequence of the four steps necessarily is fixed because of the

consequential relationship among the problems typical of the several

steps. The mission, in the first step, furnishes the nature of the

appropriate effect desired. Until modified or revoked by higher

authority, it clearly remains the governing influence throughout the

entire range of mental effort which, in conjunction with the moral and

physical effort, is calculated to result finally in the attainment of

the assigned objective.

The procedure involved, being natural and universal, is fundamentally

the same even in those tactical situations where the commander

performs all of the steps in almost instantaneous succession. The

Estimate Form, as presented herein, is adaptable to military problems

of any nature. The systematic approach represented in the Form is

subject to adaptation by the competent commander--provided that the

essentials are preserved--in any manner appropriate to his personal

preference and to the nature of his particular problem.

The essentials of the military Estimate of the Situation, as a

specialized use of the natural mental processes, are inherent in the

proper application of the Fundamental Military Principle (see page

82). The Estimate Form merely provides a more detailed guide for the

use of the Principle. Facility in the use of the Principle will enable

the competent commander, once he has formed a proper understanding of

the basis for solution of a problem, to solve the problem correctly

without reference to the Estimate Form. Reference to the Form may be

necessary in problems of broad scope, in order to ensure a complete

survey of factors of fighting strength. Time, in such cases, is

usually available for purposes of a detailed study. Subject to this

exception, the Principle, alone, may be used effectively as a basis

for sound military decision,--a fact of particular significance where

time (page 22) is an element of immediate concern.

That this procedure may be successfully and repeatedly applied in the

fast-moving events of the decisive tactical engagement is, more

particularly, the goal of mental preparation for the exercise of

command.

THE EXERCISE OF PROFESSIONAL JUDGMENT

IN PLANNING

CHAPTER VI

THE SELECTION OF A CORRECT OBJECTIVE

(Including the Determination, in Proper Detail, of the Action Required

for its Attainment)

The First Step--The Solution of a Basic Problem (The Estimate of the

Situation)

The type of problem distinctive of the first step, now to be

discussed, is a basic problem. It is the most likely type when

an organized chain of command is in effective operation, the

incentive for solution being derived from a directive issued

by higher authority (Chapter V).

The problem of the first step is described by the question,

"What objective should I select, and what action (in outline)

should I take for its attainment, in order to achieve the

objective assigned to me by higher authority?"

The procedure for solution of the type of problem distinctive of the

first step is that already indicated as applicable to all military

problems, i.e., a specialized employment of the natural mental

processes (Chapter II) through the application of the Fundamental

Military Principle. The studied application of the Principle is

assisted through the Estimate Form which provides a more detailed

guide.

The fundamentals of the Estimate Form have already been discussed

(Chapter V). Except for emphasis, or to afford a basis for further

detailed discussion, the basic matters previously dealt with are not

repeated in the present chapter. It is therefore advisable, before

studying the details applicable to the first step, to make an adequate

review of the pertinent portions of the preceding chapter. With the

necessary background thus provided, the Estimate Form can be followed

with a minimum of distraction caused by reference to related subjects.

For special emphasis, it is repeated here (see also page 110) that the

Estimate Form is a flexible guide. The commander is of course at

liberty to vary the procedure according to his particular needs and

the nature of his problem; however, he will bear in mind that errors

of commission or of omission arising by reason of departure from the

essential features of the procedure may disrupt orderly reasoning.

The Estimate Form is divided into sections and sub-sections, each of

which presents a subject for consideration. The Form follows,

sequentially, the salient features of the natural mental process

described in Chapter II. It will be seen, from an examination of the

section headings listed below, that Section I has to do with

establishing the basis for solution of the problem; Sections II, III,

and IV relate to the actual process of solution through consideration

of various courses of action; while Section V states the conclusion

reached.

I. Establishment of the Basis for Solution of the Problem.

II. Determination of Suitable, Feasible, and Acceptable

Courses of Action.

III. Examination into the Capabilities of the Enemy.

IV. Selection of the Best Course of Action.

V. The Decision.

A tabular form inserted in the Appendix lists the foregoing headings

and their principal subdivisions within the Estimate Form. For

convenience, the appended Form also includes page references to the

discussion in this chapter.

SECTION I

ESTABLISHMENT OF THE BASIS FOR SOLUTION OF THE PROBLEM

As noted in the Fundamental Military Principle, each objective, prior

to its selection, and each operation, prior to its adoption, requires

examination from the standpoint of suitability, feasibility, and

acceptability. Suitability involves the factor of the appropriate

effect desired; feasibility involves the factors of the means

available and opposed, as influenced by the characteristics of the

theater; and acceptability involves the factor of the consequences as

to costs.

In order to establish a sound basis for the solution of a military

problem, one which will permit the tests for suitability, feasibility,

and acceptability (see pages 98-102) to be intelligently applied, it

is necessary that the factors involved be studied.

A. The Appropriate Effect Desired.

The appropriate effect desired, the first factor listed, is the goal

toward which the commander is working. He is enabled to form an

understanding of this essential aspect of his problem through (1) a

grasp of the salient features of the situation, (2) a recognition of

the incentive to solution, and (3) an appreciation of the assigned

objective. He expresses this understanding by (4) formulating the

mission.

The sequence in which the commander takes up these considerations is a

matter for his own choice. Usually, directives from higher authority

(see Chapter VIII as to the Order Form) give him, first, information

as to the situation; thereafter, such directives assign him a task (or

tasks) involving one or more assigned objectives. For this reason, the

sequence so indicated is the one utilized here.

(1) Summary of the Situation. Before the commander can decide whether

he wishes to maintain the existing situation or to change it, he

requires a mental picture of its salient features. On beginning the

Estimate, the available information is therefore briefly summarized.

The picture presented here will show in broad outline (page 79) the

opposing forces as disposed in localities which constitute relative

positions with reference to each other. Details are reserved for

Section I-B of the Estimate.

The appropriate data are noted on the chart, and study of the chart

goes hand in hand with the development of the Estimate.

The summary of the situation may include statements as to present

activities of own and enemy forces. It may recite significant

occurrences. It does not attempt to compare or to deduce; such

processes are deferred until Section I-B. The commander extracts, from

the information furnished by higher authority, such data as are

pertinent to his own problem. He includes these data in his own

summary, supplementing them by information from other sources, to the

extent deemed advisable. In the exercise of judgment as to the content

of his summary, the commander is influenced by the fact that the

summary is the point of departure for visualizing the appropriate

effect desired.

(2) Recognition of the Incentive. In basic problems (the type now

under discussion, see page 117), the commander finds his incentive in

directives received from higher authority. Under the procedure of the

Estimate, a notation of that fact, with a citation of the

directive(s), is all that is required to indicate that the commander

has formed a proper recognition of his incentive.

(3) Appreciation of the Assigned Objective. A correct understanding of

the nature and of the involvements of the assigned objective is,

naturally, an essential to the establishment of the basis for the

solution of a problem of the first step.

At this stage of the Estimate the commander cannot, however, expect

always to reach a final conclusion as to this matter. He will have

opportunity for further consideration, later, in Section II. It will

be realized that, after intervening portions of the Estimate have been

worked out, the commander will be in a position to examine the

assigned objective again, and to make a more thorough analysis.

In a basic problem, the commander is assigned his objective by higher

authority, usually in the form of an assigned task. Although, as

stated on page 84, such task may be expressed by one of various

methods, a properly conceived task always indicates, either

specifically or inferentially, an objective (or objectives).

Whatever method of expression may have been employed by higher

authority, the commander will facilitate his appreciation of the

assigned objective if he now sets down his assigned task, scrutinizes

it carefully, and then makes note of the objective which is either

specifically or inferentially indicated by that task. (See pages

52-54).

The commander's basis for solving the problem is not complete,

however, with merely a statement of his own objective. Full

visualization of the effect desired is not obtained until the

commander appreciates not only the result which he, himself, is

required to accomplish, but also the next further result which is

expected to eventuate as, at least in part, an effect of his

accomplishment. His goal, as an "effect desired", includes not only

the effect desired of him by higher authority, but also the effect

which his immediate superior desires to be accomplished by that

superior's entire force.

Occasionally, full appreciation of the commander's objective will

require, also, consideration of the further effects desired by yet

higher successive echelons.

The natural requirement is that the goal be so clearly defined as to

obviate any material doubt as to the implications involved in the

commander's assigned objective. When the goal has been thus defined,

there results a linking of effect and further effect, of objective and

further objective,--in short, of task and purpose,--the importance of

which has previously been emphasized (page 48).

In making notation of this further objective for the solution of

problems typical of the first step, the commander normally sets down

the general plan of his immediate superior for the employment of the

latter's entire force. When the linking of objective to objective,

echelon by echelon, has involved no complication, the immediate

superior's general plan will be a sufficient indication of the

purpose for which the commander is to carry out his task.

(4) Formulation of the Mission.

The linking of the commander's assigned task to the general plan of

his immediate superior permits the commander to formulate his mission

(page 87). His assigned task becomes the task of his mission; his

superior's general plan becomes the purpose of his mission. In this

manner he crystallizes into a clear statement the part of the common

effort which he is to carry out, indicating the assigned objective he

is himself to attain, as well as the further objective to whose

attainment his effort is to contribute.

In establishing the basis for solution of his problem with respect to

suitability, the commander may have considered his assigned objective

before studying his situation. If so, he may now desire to modify his

earlier statement of that objective, before incorporating it in the

formulation of his mission, to the end that a more clear-cut and

concise expression may be obtained.

The relationship (restated from page 87 for emphasis) is expressed in

the following;

My assigned task is to be accomplished for the purpose of

carrying out my designated part of my superior's general plan.

This formula is customarily simplified to the following:

(Task) (statement of the assigned task),

(Purpose) in order to assist in the successful execution of

(statement of the superior's general plan).

The words "assist in the successful execution of" may frequently be

understood and therefore omitted.

The mission, thus formulated, clearly indicates the appropriate effect

desired, i.e., the factor which establishes the basis for the solution

of the problem from the standpoint of suitability.

B. Relative Fighting Strength.

As indicated in the Fundamental Military Principle, the second and

third requirements for a sound solution of the problem are feasibility

of accomplishment and acceptability of the consequences as to costs.

Both requirements have to do with the factors of relative fighting

strength. Fighting strength is derived from the means available as

influenced by the characteristics of the theater. Relative fighting

strength is determined by a weighing of these factors against the

means opposed, as influenced also by the characteristics of the

theater.

These are the factors, then, which are next studied in the Estimate.

They are studied in order to complete the establishment of the basis

for the solution of the problem.

* * * * *

The factor of consequences, as listed in the Fundamental Military

Principle, is related to the factors pertinent to feasibility. This is

true because consequences are assessed, in the Estimate, on the basis

of the envisaged results of proposed actions. These results are

necessarily predicated on the grounds established by consideration of

the factors of relative fighting strength. The study of relative

fighting strength thus provides not only a sound basis for the

determination, later, of the feasibility of courses of action, but

also of their acceptability with respect to consequences as to costs.

Particular emphasis is placed on the conclusion as to relative fighting

strength, to the end that specific advantages may be ascertained. Such a

study is primarily concerned with information:--its collection, its

analysis, its evaluation, and its interpretation so as to convert it

into military (naval) intelligence (page 76), with a view to its use by

the commander in the solution of his problem. Information as to forces

present and as to their positions is of course prerequisite to a clear

comprehension of the possibilities as to physical objectives, as to

relative positions, as to apportionment of fighting strength, and as to

freedom of action.

The commander may choose whether he shall, in his estimate, first

consider the means available and opposed, or reverse the order and

give priority to the characteristics of the theater. In a particular

situation, the significance of these characteristics is frequently

determined by the capabilities and limitations of the means available

and opposed. For this reason, these means are first discussed in this

treatment, which thereafter includes the analysis of the

characteristics of the theater.

The capabilities and limitations of the means, and the significance of

the characteristics of the theater, may be expressed in terms of

certain specific factors (page 25). Each of these factors may

influence, or be influenced by, any or all of the others. Situations

occur in which certain factors exert little or no influence. Yet, in

other situations, these same factors have a paramount effect.

The classification of factors utilized in the following treatment is

applicable to most military problems.

A list of pertinent factors, to be of real use in the solution of

problems, is required, first, to be complete, so that no factor will

be overlooked, and, second, to be simple, so that, as far as

practicable, all similar data may be discussed under one heading.

With respect to the factors set forth in succeeding pages, the

solution of a particular problem may call for a different listing.

Such listing may involve, in some cases, the contraction or the

omission of certain of the headings.

In other cases, an expansion will be necessary or desirable under

certain headings, in considerably greater detail than shown here. For

example, Section I-B of a National Estimate may involve reference to

several volumes of printed books or of similar data, while, even in

ordinary strategical situations, numerous charts, books of sailing

directions, and other compilations may require study. Where such

references are not standard and generally available, they may be

appended, preferably in condensed form.

The proper listing of pertinent factors will depend on the nature of

the problem.

(1) Survey of the Means Available and Opposed.

The application of power, actually or by threat, is dependent on the

ability of the human and material components of fighting strength to

develop energy and to exert effort for purposes of combat (page 8).

These components, as ranged on one side or the other, constitute the

means available and opposed. (See page 31). Analysis of these means

requires a classification of the various factors which influence the

situation.

For a broad strategical estimate made by the State, economic and

political factors require intensive study; physical objectives,

relative position, apportionment of fighting strength, and freedom of

action are all involved in such a survey.

For a strategical estimate made by a high military commander, these

factors frequently enter to a lesser extent. Such a commander is

concerned only with the effect which these factors will have on the

operations projected for the particular theater involved in his

problem. From his point of view, the economic and political factors

often have little bearing on the elements of a favorable military

situation. In such a case, the commander concentrates in this section

on the factors more directly relating to the armed forces; his

important considerations deal with such matters as numerical

strength, types of weapons, disposition, and factors as to freedom of

action.

For strategical estimates of lesser scope, the commander further

restricts his study accordingly.

In detailed tactical estimates the commander requires an exhaustive

comprehension of the fighting capabilities of his own and the enemy

armed forces, because his selection of physical objectives and his use

of relative position are affected by such considerations. This is

manifestly true for studied tactical estimates made in advance to meet

contingencies, but its import is not always fully understood in its

bearing on the unfolding situation after the battle begins. At that

time, the most precise knowledge is called for, under the then rapidly

changing conditions. (Chapter IX.)

In the Form treated herein, those matters particularly applicable to

broad estimates are included under "general factors". These are

followed by the factors more directly applicable to the armed forces.

(a) General Factors. (i) Political Factors. The prosecution of the war

is directly influenced by such internal conditions as the strength of

the national government and its capacity for unified effort, the

moulding and maintaining of a firm public opinion in support of war

aims, the neutralization of subversive propaganda, and the degree to

which the government can make available necessary resources, both

domestic and foreign.

External relations modify the conduct of war, always affecting broad

estimates of the employment of national forces. The wartime factors

which influence these relations include the effect of the clash

between foreign opinion and national policy, the national bias of

interested neutrals and of unneutral non-belligerent governments, and

the normal attitude of such neutrals and non-belligerents toward each

belligerent. The diplomatic skill of the opposing governments and the

ability of propaganda to sway public opinion abroad may well determine

the manner in which neutrality will be enforced.

Alliances, including those that are known and those that are secret,

directly influence an estimate. When a war of any importance breaks

out in any part of the world, all States are affected to some degree.

One may have an alliance which, though not requiring active

participation in the war, will call for collaboration with the efforts

of a belligerent. Another alliance may require active participation,

while still another State may attempt to maintain strict neutrality.

Every State remaining at peace will thus be in a status ranging from

that of a non-belligerent, with more or less close ties to one of the

contestants, to a position of strict impartiality. The estimate of the

international situation becomes more complex as the magnitude of the

war increases. A correct appreciation of the status of each State

concerned is of first importance in any broad estimate of the conduct

of war.

(ii) Economic Factors. The capacity, organization, and mobilization of

industry influence the rapidity and adequacy with which material is

prepared for, and supplied to, the armed forces. The acceptance by the

civilian population of sacrifices, caused by the diversion to war uses

of the productive capacity of industry, will have a direct bearing

upon the industrial capacity of that State.

The ability and willingness to finance the war effort, which includes

the ability to tax, to float internal loans, and to create foreign

credits, may well determine the extent and duration of the national

capability for war.

The dependence of a nation upon the continuation of foreign trade,

including the necessity of obtaining new markets and new sources of

supply, affects its strength. No State yet has complete autarchy.

Thus, there is the necessity of obtaining from foreign sources certain

of the raw materials which are indispensable to the war effort. As

each belligerent may endeavor to deny sources of raw materials to the

other, a portion of the fighting power may be required for trade

protection.

(iii) Psychological Factors. The maintenance of a stable morale (page

72) at a high level is a primary concern. Such stability inures the

nation or command against the full effects of surprise, fear,

disappointment, despondency, and other weakening moral influences,

while at the same time taking full advantage of those influences which

strengthen the moral fiber of a people.

Training and experience influence morale, playing a part difficult to

overestimate. They provide a basis for evaluating discipline. A study

of the history of the State may prove valuable in estimating the

present condition in this respect; a nation or command which may be

classed as a veteran has an advantage over a beginner at the art of

war.

Another important factor relates to the existence of the skills

necessary for the production and use of the material means of war. The

control of skilled personnel is a psychological consideration of

great importance.

Unity of effort, or the lack of it, especially between management and

labor, may be one of the most important factors of the estimate.

Special attention is desirable as to national inventiveness and

versatility in the production of new and surprising means of war or in

development of methods that in any way contribute to a successful war

effort.

Racial or national characteristics may affect the estimates of morale

and training. Reactions of various races or groups to the conditions

of war have been sufficiently recorded, on the basis of past

performance, to prove of some value. Service traditions may furnish

clues for correct evaluation of psychological factors.

While only the physical elements of fighting strength are susceptible

of quantitative comparison, failure to take account of mental and

moral factors may involve serious error. Nevertheless, in many

situations, such factors remain relatively indeterminate until

subjected to test. Inferences may be drawn, and deductions made, on a

basis of peace-time observation and of historical precedent. In these,

racial and national characteristics may figure prominently. History,

however, has taught that, in a conflict between modern industrial and

military nations, it is unwise to entertain any assumption other than

that of moral equality until such time as the conflict has

demonstrated the existence of a difference, and the degree thereof, or

unless prior experience, observation, and acquaintance unquestionably

warrant otherwise.

(iv) Information and counter-information measures. Operations of war

are tremendously affected by the information which each belligerent

possesses of the others. It is therefore of vital importance to weigh

the efficiency of the belligerents in the employment of means of

obtaining, denying, and utilizing information.

There may appropriately be considered present, probable, or possible

use or non-use of indirect methods such as: study of press, captured

documents, and material; reports from other friendly units;

interrogation of prisoners of war, deserters, inhabitants, and escaped

or exchanged prisoners; radio direction-finding; efficiency of

cryptography; interception of enemy radio, telegraph, telephone, and

mail communications; espionage; censorship; propaganda; efficiency of

communications systems, ashore and afloat, which include all means of

interchange of thought. In this connection it will be recalled that

information, however accurate and appropriate, is useless if it cannot

be conveyed in time.

The direct methods of obtaining information are military operations

intended for that purpose, such as observation, reconnaissance,

scouting, trailing.

Counter-information measures are no less important than those

pertaining to collection of information. Such measures include all

provisions for secrecy, such as censorship, counter-espionage,

cryptography, control of own communications, security of documents,

camouflage, and applicable tactical operations.

(b) Factors More Directly Applicable to Armed Forces, (i) Vessels,

including aircraft. The numbers and characteristics, of the ships and

aircraft of the various nations of the world are known with less and

less accuracy from the time when war becomes a probability. The

information available is given intense and comparative scrutiny, under

the specific headings of the factors of the Estimate Form as later

enumerated.

(ii) Land forces, including land-based aviation. Important facts

concerning the land forces of the enemy, including his land-based

aviation, will be known, probably, to a lesser extent than in the case

of the naval forces. The value of a comparison--naval, land, or

air--may depend upon whether the intelligence service has improved the

accuracy of these data, maintained them up to date, and collected

accurate additional information.

(iii) Personnel. The status of enemy personnel as to the sufficiency

of numbers effectively to man all implements, as to training, morale,

skill, stamina, and willingness to accept the supreme sacrifice, can

seldom be accurately known. Unless there is positive information to

the contrary, the wise commander will assume in this respect that the

status of the personnel available to his opponent is at least equal to

that of his own command. Full consideration will be given to all known

facts concerning own personnel, to the end that its worth in any

proposed situation may be properly evaluated.

The basic discussion of the psychological factors (page 125) is

applicable here as to the respective armed forces. Personal

characteristics of commanders, so far as known, deserve full study,

since they have an important bearing on relative fighting strength.

The military value of the various units and forces is a similar

consideration. The present attitude and past actions of enemy

commanders and of their commands, and the factor of racial, national,

and service characteristics, may furnish clues for correct evaluation

in this connection.

(iv) Material. The material characteristics of the commander's own

implements of war are generally known to him. The characteristics of

enemy material can only be estimated from such data as have become

available, but are not to be underestimated.

Material characteristics embrace armament, life, and mobility.

Armament relates to the caliber and number of guns, and to other

weapons such as torpedoes, mines, depth-charges and aircraft (with

their own weapons). It also includes chemical agents and other

instrumentalities, together with the types, potentialities as to

range, and the number or amount of each available, both for immediate

use and as replacements. Ammunition supply is a factor here. In the

evaluation of foreign armaments, sufficient data are often available

to make a reasonable estimate, but care is desirable not to

underestimate.

Life is the ability to withstand punishment; it is expressed in terms

of standards which can be clearly visualized. For a vessel, life is

the ability to absorb damage while carrying out its assigned task. In

the absence of definite factual data, evaluation of the life of

foreign vessels will sometimes prove difficult. Here, again, an

underestimate is dangerous.

Mobility is capability of movement. It is compounded of the elements

of speed, radius, and the ability to operate under imposed conditions

of weather, visibility, hydrography, and other possible obstacles to

certain and free movement. Mobility is one of the most important

factors pertaining directly to relative position, to apportionment of

fighting strength, and to freedom of action. Closely related factors

are the organization, disposition, and methods of operation of the

enemy, and of own forces. Accurate knowledge of these factors, before

an operation, greatly enhances the possibilities of dealing

effectively with the enemy.

The condition of the implements of war embraces such factors as the

efficiency of motive machinery, the integrity of underwater

compartments and other material construction, and physical endurance.

The last applies not only to material, but also to living beings, and

involves the ability to withstand the wasting effects of operations,

whether due to fatigue, hardship, disease, worry, wounds, or other

causes. Here again, it is obvious that the commander will often have

only an imperfect idea of the condition of the enemy in this respect.

His experience will lead him to form an accurate estimate of his own

condition. Definitely, unless he has positive information to the

contrary, he assumes that the condition of the enemy is no worse or

better than his own. (See also the psychological factors, page 125 and

the personnel factor, page 127).

(v) Logistics support is of primary concern to the commander. In the

naval service, this is particularly true of the strategical estimate.

While the factor may also have some bearing on a tactical estimate,

logistics support will rarely change sufficiently, during a naval

battle, to affect the outcome. This support exercises a dominant

influence upon the fighting power of armed forces. It is concerned

with the availability, adequacy, and supply of the following:

Material: items such as fuel, ammunition, weapons, aircraft,

food, clothing, spare parts, repair materials, animals,

and general supplies.

Personnel: military and civilian; number and quality of

replacements.

Facilities: factors such as bases; manufacture and repair

facilities, afloat and ashore; shelter; sanitation;

hospitalization; recreation; transportation; education;

counter-espionage; counter-propaganda.

The limitation imposed upon operations by logistics represents the

final limit of a commander's plan of action.

(2) Survey of the Characteristics of the Theater of Operations.

The characteristics of the theater of operations exert an influence,

always important, sometimes paramount, upon the possibility of

attaining the objective, and upon the strategical and tactical

operations that may be employed.

At this point in his estimate the commander utilizes his charts,

intelligence reports, and hydrographic publications to make a factual

study of the theater. This study is not for the purpose, at this time,

of drawing any conclusions as to possible courses of action, but to

furnish data which will assist in consideration of later sections of

the estimate. The study may be made under several important headings,

as follows:

(a) Hydrography. A study of the hydrography will determine the depth

of water, the existence of shoals, the presence of unusual currents,

the rise and fall of the tides, the availability of channels, and

other pertinent features. These are recorded for later use.

Shallow water may permit mining or may prevent the operation of

submarines. On the other hand, the ability to mine in shallow water

may be curtailed by strong currents or by the rise and fall of the

tide. Again, the depth of water, the strength of currents, and the

range of the tide may determine the feasibility of netting the

entrance to a port or base. In a tactical action, advantage may be

taken of shoals to limit the freedom of action of the enemy, without,

however, interfering with that of one's own forces.

(b) Topography. The topography of the area is also frequently of

interest to the naval commander. In actions close to the shore, the

character of the coast may play an important role. A high bluff,

combined with considerations as to light, may create a very definite

advantage or disadvantage in a naval tactical situation.

Topography may be a most important consideration in determining what

bases are to be used. The commander makes note of the topography of

the various possible bases; later in his estimate, the natural

features lending assistance to the defense of the various sites may

play an important part in the selection of bases.

The use of channels may depend upon the topography of the bordering

land. Questions arise as to whether such land can be seized and held,

or, if in friendly hands, whether it can afford adequate protection to

the channel.

In any landing operation, the topography of the area to be occupied

may be the controlling factor.

(c) Weather. The seasonal weather in the theater will have a direct

bearing upon operations. The use of aircraft, the employment of light

forces, the habitability of ships over long periods, the use of smoke,

the range at which a gun action may be fought, the effect of spray and

gases,--these considerations are but some of the matters which will be

affected by weather.

The possession of, and the position of, meteorological stations within

the theater are of growing importance in the successful planning of

coordinated air, submarine, and surface operations.

(d) Daylight and Dark Periods. It may be well under this heading to

put in tabular form the times of sunrise, sunset, moonrise, moonset,

the phases of the moon, and the duration of morning and evening

twilight. When, for example, the commander is considering night

destroyer attacks, the operation of submarines, or the type of

protective screens he desires to use, he may profitably refer to these

tabulations.

(e) Relative Location and Distance. No part of the study of the

characteristics of the theater is of greater importance than that

pertaining to relative location and distance. At this point it may be

found advantageous to place in tabular form the distances between the

important positions within the geographical area of the theater. This

study furnishes knowledge as to the availability of certain localities

for use in support of, or in cooperation with, forces at other

localities, and as to distances in relation to steaming capabilities

of the various units which make up the commander's force.

(f) Lines of Transportation and Supply. The usual sea routes which

pass through the theater are an important subject of study; also,

particular focal points, defiles, and restricted waters which are, or

may prove to be, critical areas with respect to own or enemy forces.

Other items are the significant routes from home or enemy territory,

i.e., the lines of communication, the terminal points, and the

flanking positions along these lines.

(g) Facilities and Fortifications. The facilities for the support,

upkeep, and repair of the units of the commander's forces and of the

opposing force, as well as the fortifications existing within the

area, may require consideration. Other features which may render a

port or base of value, or which may indicate a possible necessity of

denying it to the enemy, also merit attention.

(h) Communications. In strategical estimates, more particularly in

broad ones covering large theaters, study of communications involves

not only those means under the commander's control, but also his

relation to the system of regional and national communications

operated by his government. Examination is made into the established

physical stations; such examination includes radio, cables, and

perhaps land wires.

In tactical estimates the means of communication which affect the

engagement are more directly those under the control of the commander.

An examination into the organization of the means to meet conditions

prevailing in the theater is appropriate here.

Another aspect of communications is that of maintaining all forms

against enemy interference. The importance of this feature in planning

may not safely be overlooked, and careful study is indicated to

provide for guaranteeing communications during action. The

characteristics of the theater, as they relate to this feature, are

considered here.

For the same reason, consideration of interference with enemy

communications is included, so far as significance attaches to them

with respect to the theater of operations.

This portion of the Estimate Form varies greatly with the type of

problem under consideration. However, in all estimates, this is the

place where the commander searches the theater for factors affecting

communications for the particular problem.

* * * * *

With the completion of this subsection of the estimate, the commander

has assembled and placed in workable form the information to which he

expects to refer in the succeeding parts of the estimate.

(3) Conclusions as to Relative Fighting Strength.

Having surveyed the means available and opposed, as well as the

characteristics of the theater of operations, the commander will find

it useful to summarize the pertinent information available, in order

that the strength and weakness of own and enemy forces can be readily

visualized and compared. Thus the existing advantages and

disadvantages are made apparent, and conclusions are drawn as to

relative fighting strength.

A satisfactory procedure is to place strength and weakness factors in

parallel columns for own and enemy forces. From careful consideration

of the facts so far determined in Section I-B, there are extracted and

expressed briefly the pertinent strength and weakness factors.

It is usually easier to determine all the strength and weakness

factors in detailed tactical estimates than in broad strategical

estimates.

The former deal in relatively more factual terms, with definite

comparisons such as with respect to maximum speeds, numbers and

caliber of guns, numbers and types of aircraft, numbers and types of

torpedoes, and other such items which give the factual basis for

comparison.

In broad strategical estimates, this factual basis is present, e.g.,

as to distances, radii of ships, geographical locations of forces, and

the like. But other factors may not be so definite, especially as

regards enemy forces. For example, it will often be difficult for the

commander to say that the enemy's logistics problem is easier or more

difficult than his own, unless he has a good idea of the amount of

fuel, ammunition, and stores available to the enemy within the time

limits involved. The evaluation of training, spirit, health, and

courage of personnel is, as previously noted, relatively easy to

determine for own forces, but more or less of a conjecture in regard

to the enemy.

The value of the entries in the parallel columns at this point of the

estimate will depend upon the skill of the commander in judging the

factual data contained in all of the known factors of strength and

weakness. The proper entries to be made will depend upon

circumstances. In one estimate, for example, the anti-aircraft

armament available to a carrier group will be of vital importance. In

another estimate of the same carrier group, anti-aircraft defense will

be of no importance because no enemy aircraft can be employed in the

situation being estimated. Again, in a local tactical situation, if

the ships involved have just been fueled, the economical steaming

radius may be of no immediate importance. And while the total amount

of high-test gasoline which can be produced in a State in the coming

year may be vital to a broad strategical estimate involving war

against trade, that information may be of little use in a tactical

estimate of a localized, fleeting situation.

Thus, in determining what factors to evaluate, and in assessing their

relative value, the commander considers only such as can possibly

affect the effort to be made in the theater under consideration. The

summary of strength and weakness factors is, then, a summary of those

factors which the commander considers will affect the character of his

effort. This summary indicates the relative importance of such

factors.

A mere list of facts will not serve the purpose. What is needed here

is a series of evaluations and conclusions which may result from a

study of the pertinent details.

With the circumstances attending his particular problem clearly in

mind, the commander carefully reviews each of the factors of fighting

strength in the theater; he classes each as either a strength or

weakness factor for himself or his opponent, and enters it in the

proper column. A strength factor for one is not necessarily entered as

a weakness factor for the opponent:--what is required is a

well-digested summary of the factors which give to either side an

advantage or a disadvantage as compared to the other.

NOTE

The Estimate procedure has, to this point, established the basis for

the solution of the problem through evaluation of the factors

pertaining to the requirements of suitability, of feasibility, and of

acceptability of the consequences as to costs.

On this basis, the commander is ready to consider such courses of

action as may be pertinent. To this end, he has a choice of

procedures. He may first consider courses of action for himself. He

may prefer, however, to consider first those which are applicable to

the enemy.

If the commander considers his own courses of action first, this

procedure has an advantage in that it narrows, later, the scope of

enemy courses which are pertinent to his situation. This is true

because consideration of enemy courses may in such a case be

restricted to those which give promise of countering, effectively, his

own courses of action.

This procedure may also have a certain psychological advantage, in

that the commander may thereby avoid becoming unduly impressed by the

potentialities of enemy action. Occasionally, prior consideration of

enemy courses may tend to put the commander, unnecessarily, on the

mental defensive.

First consideration of his own courses of action is especially

appropriate for a commander whose mission requires him to assume the

initiative, particularly when the relative fighting strength indicates

that he can compel enemy action to conform to his. This is frequently

the case when enemy action will chiefly affect details rather than the

general trend of the operations.

These reflections indicate that first consideration of his own courses

of action will very frequently be advantageous to the commander. Such

a sequence is therefore indicated preferentially in the Estimate Form,

and next discussed. However occasions may arise when consideration in

the reverse order is preferable. Sometimes the prior consideration of

enemy potentialities has the advantage of making the commander's

estimate more complete with respect to the obstacles which he is to

overcome. Furthermore, when the effectiveness of his future action is

seen to depend chiefly upon what the enemy can do, or when the

initiative lies manifestly with the enemy, and when the commander's

mission requires him to frustrate enemy action, rather than to assume

the initiative himself, the prior consideration of enemy courses of

action may be indicated.

The commander may therefore consider the subject matter of Sections II

and III in the order hereinafter followed, or he may reverse that

order.

SECTION II

DETERMINATION OF SUITABLE, FEASIBLE, AND ACCEPTABLE COURSES OF ACTION

A. Analysis of the Assigned Objective.

In order further to clarify the problem, consideration of the

commander's courses of action may profitably commence with an analysis

(page 53) of the assigned objective. Section I-A contained an

appreciation of this objective on the basis of the salient features of

the situation. A close examination is now possible in the light of the

additional information furnished by the full details (Section I-B) as

to the means available and opposed, and as to the characteristics of

the theater (page 121).

Accordingly, the mission (page 121), is now again stated, and is

restudied. The task is thoughtfully examined anew, in view of the

forces and positions now known. The purpose is scrutinized with equal

care, because it indicates the further end in view for the common

effort. Now, obstacles to success which, in Section I-A, could not

fully be appreciated can be examined against the background afforded

by visualization of the enemy's ability to oppose the attainment of

the assigned objective.

This analysis calls for such discussion by the commander as is

essential to better understanding of his assigned objective. Some

restatement and repetition may be desirable as to the subjects already

discussed under the appreciation of the assigned objective. In solving

certain types of problems, where simple estimates, only, are required,

there may be no necessity for further treatment. Even in these cases,

however, the commander restates his mission in this subsection, in

order to ensure a clear comprehension of its task and purpose, as a

sound basis for his further solution of the problem.

B. Survey of Courses of Action.

The Fundamental Military Principle (page 41) represents an equation

(page 23) based on five factors: the appropriate effect desired, the

means available, the means opposed, the characteristics of the

theater, and the consequences as to costs. Of these five factors, all

but the last (the consequences as to costs) have by this time, in the

course of the estimate, been assigned values as definite as the

commander's information and his study permit.

From this point on, the problem is to evolve tentative solutions

(courses of action) and to test them (page 98), severally, by

reference to the factors. The tests as to suitability and feasibility

can now be made with reference to the known factors. The test as to

acceptability of the consequences involves an unknown factor. However,

for each tentative solution of the problem, a value can be assigned

for this factor, because all five factors are interdependent (pages 32

and following), so that the value of any of them can be set by a study

of the others. It is through this procedure that evaluation of the

consequences factor is accomplished (an application of the corollary

Principle of the Acceptable Consequences as to Costs, page 35).

By means of the standard tests, the several tentative solutions are

also compared to each other in the light of envisaged enemy action, so

as to enable the commander to select the best solution.

* * * * *

The commander now, as a result of his reflective thinking as to

courses of action, makes a list of those which he has visualized for

himself. There may be one course of action, or many; ordinarily there

are several.

Examples of courses of action have been given in the basic discussion

of the subject (pages 89 and 92). In listing his courses, the

commander can add to clarity of thought and of expression by

visualizing the objective embodied in each course and by envisaging

also, the action, expressed in proper detail, for its attainment. This

process is naturally the more important when the objective is inferred

rather than specifically expressed, and when the action involved calls

for more description than can be obtained merely by stating the

objective.

For example, the commander may include a course of action such as "to

raid enemy trade in the area EFGH". The objective is here inferred; it

is not clearly stated. The commander may therefore be well advised to

add a notation of what the objective is; indeed, more than one

objective may be involved. Objectives thus inferred might include,

when specifically stated, the infliction of damage on enemy trade, the

infliction of damage on enemy combatant forces protecting such trade,

the disruption of enemy supply arrangements, or such others as may be

applicable.

This clear visualization is essential to the establishment of the

relationship between the assigned objective and the objective inherent

in the course of action (page 89). If, for instance, the motivating

task is to "divert enemy forces to the area EFGH", the commander may

consider the course of action "to raid enemy trade in area EFGH". By

infliction of damage to, and by disruption of, enemy supply

(objectives of his raiding), he expects to accomplish the diversion of

enemy forces to the area EFGH, because the enemy will wish to protect

his trade against such raids. The relationship between the assigned

objective and the objective inferred in the course of action is thus

made clear.

With regard to expression of the action to be taken, the commander may

properly desire to be more explicit than by merely saying, for

example, "to destroy the enemy". Here the objective is clear (it is

"the destruction of the enemy"), but the expression of the action is

so general that additional description may be needed. Examples of more

explicit statement have been given previously (page 89).

On occasion the higher commander may predetermine the commander's

course of action for the attainment of the objective assigned to the

latter. Circumstances under which such procedure may be properly

applicable, and the effect which it has on the commander's estimate,

have been previously discussed (page 86).

C. Application of Tests for Suitability, Feasibility, and

Acceptability.

The courses of action which the commander has envisaged are now

subjected to test (page 98). This essential stage in thought is

intended to put the courses of action to proof as tentative solutions

of the problems. The principle here recognized is that suggestion has

no logical nor rightful claim upon action or belief until it has

received adequate confirmation. Such confirmation is, in part,

provided by these tests.

The tests applied are for suitability, for feasibility, and for

acceptability as to consequences. Each of these tests is a separate

one. Each course of action is formally subjected to test. When the

tests are completed, the courses of action stand classified in these

respects. During these tests, some courses of action may be rejected;

such are then omitted in the final classification.

These formal tests are not to be confused with the preliminary tests

already given by the commander to each course of action as it occurs

to mind. Necessarily, there is such a preliminary test, because the

commander does not wish to entertain inappropriate courses of action.

For a competent commander, the mental power to envisage solutions of a

military problem is so much grounded in experience that appropriate

suggestions are most likely to occur; in fact, discriminating thought

with respect to military problems is natural for such a commander.

This immediate discrimination is, however, merely the preliminary

test. It prevents setting up wooden soldiers only to knock them down,

but it does not necessarily subject each suggested solution to a

thorough analysis.

The commander may apply the tests to each course of action as it

occurs to his mind. This procedure, however, may be rendered

impossible by the fertility of suggestion; perhaps the commander has

thought of several courses of action practically simultaneously. It

is, therefore, often better to apply the tests to all of the courses

of action, in turn, during a separate stage of the process of

thinking. This is the procedure indicated herein, as standard, by the

sequence of steps in this section of the Estimate. The process of

testing, itself, may bring to mind those combinations of courses of

action previously referred to (page 93).

The degree of formality characteristic of the tests varies with the

nature of the problem. In a broad strategical estimate, these tests

may be searching and extensive; they may then consume much time. Yet,

if the commander, in making a quick decision of great urgency in

actual battle, does not apply the tests, he may adopt a course of

action leading to tragic results. In such circumstances, the competent

commander, under pressure of danger, grasps the whole complex

situation without loss of time. He is not carried away by any chance

impressions. He does not overlook what is significant in the

unexpected event. Because he is mentally prepared for the exercise of

command (page 114) he sees things in their true proportions (page 4).

In immediate response, he coolly chooses the same course of action

which he would adopt if he had time for careful deliberation.

In making the tests, the commander rejects courses of action found

unsuitable in that they will not, if successfully prosecuted,

contribute to the attainment of the objective. He does not, as yet,

reject courses of action found to be promising of only partial

accomplishment of the task, because there may be later possibilities

of effecting combinations to this end.

The commander also rejects, at this point, courses of action found to

be infeasible of accomplishment. He is careful, however, not to

reject, abruptly, any which may later be found to be feasible in

combination with other courses.

Similarly, the commander now rejects courses of action found to

involve excessive consequences as to costs. Here, again, however, he

bears in mind the possibilities of later combinations.

The commander does not, as yet, make a selection of one course of

action in preference to another. He merely desires to restrict further

thought, toward his Decision, to those which are found, on the basis

of the estimate so far, to be suitable, feasible, and acceptable. He

may, however, make a selection to the extent of effecting proper

combinations whose applicability has already been demonstrated.

The commander also takes stock, at this stage of the estimate, of the

relative degree of suitability, feasibility, and acceptability of

retained courses, so far as can be substantiated.

D. Listing Retained Courses of Action.

The foregoing process indicates to the commander the courses of action

which may properly be retained as suitable, as feasible, and as

acceptable. He therefore draws up a list of retained courses and

classifies them according to the degree of their suitability, of their

feasibility, and of their acceptability with respect to consequences.

This list does not necessarily represent the final combinations of

courses of action; the incomplete solutions may yet become part of the

course of action finally selected. Also it is not impossible that

combinations already made will subsequently be recombined as a result

of further analysis.

It may be apparent to the commander at this time that he does not

have, as yet, any course of action which fulfills the test of

suitability as to scope, either originally or by combination. A later

conclusion is made (Section V) as to final combinations to achieve

full scope. This conclusion, however, may point the way, as later

observed, to a Decision adopting an objective short of that which

would, if achieved, lead to the accomplishment of the motivating task.

SECTION III

EXAMINATION INTO THE CAPABILITIES OF THE ENEMY

While the commander realizes that the Fundamental Military Principle

(page 41) governs the enemy's problem no less than his own, he has to

accept more of hypothesis and conjecture (the so-called "fog of war")

in applying the principle to the enemy's situation. The method of

reflective thinking utilized (Section II) for the commander's own

problem calls for certain further safeguards in application to the

enemy capabilities, since they are of course usually not so well known

to the commander as are his own.

Capabilities, in the meaning applicable herein, indicate actions which

the force concerned, unless forestalled or prevented from taking such

actions, has the capacity to carry out. Such potentialities of the

enemy are of course among the vital factors to be considered in

estimating the situation. In his estimate, however, the commander's

interest is not confined to what the enemy will probably do;

probabilities are subject to change, and do not, therefore, cover the

whole field of capabilities. The commander is not exclusively

interested in what the enemy may intend to do, or even in what the

enemy may be known, at the time, to intend to do; such intentions are

also subject to change. The commander is interested in everything that

the enemy can do which may materially influence the commander's own

courses of action.

In reaching a conclusion as to enemy capabilities, the commander makes

an estimate from the enemy's viewpoint and considers that the enemy

commander, faced with the counterpart of his own situation, is

endeavoring to attain objectives in furtherance of his own mission.

Each commander is endeavoring to create for himself a favorable

military situation, and to prevent his opponent from succeeding in the

same intent. The physical objectives for each may be the other's armed

forces; certain positions, sea areas, harbors, or territory may also

be likely physical objectives.

In such a parallel building up of plans, it is possible that the

opposing forces may not come, at least for a time, into actual

conflict. More especially in the initial stages, the respective plans

may lead to operations in different parts of the theater. Again, the

geographical direction of search may cause the forces to miss contact.

Moreover, unless one commander definitely makes provision to seek out

and engage, the two forces, each on the defensive, may find themselves

"shaking fists" at each other across an ocean area.

Notwithstanding this possibility, however, a conclusion, on an

insufficient basis, that the enemy will or will not seek him out and

engage him, or that the enemy will or will not do anything else, may

be fraught with the most serious consequences for the commander.

Accordingly, in estimating the enemy's situation, he puts himself in

the enemy's position, while subordinating his own hopes and desires.

He credits the enemy with the possession of good judgment and of the

resolution and ability to apply with skill the fundamentals of

effective warfare, subject, naturally, to the justified conclusions

which the commander has drawn (Section I-B) on the basis of the

available factual data as to relative fighting strength.

A. Survey of the Enemy's Problem.

This portion of the commander's estimate pertains, of course, to the

existing situation as viewed by the enemy. This fact, alone, may

inject into the problem certain factors which differ from those

applicable with respect to the commander's view of his own problem, as

determined to this point.

(1) Summary of the Enemy's Situation.

Frequently it may happen that the enemy does not have certain

significant information. The fact of such lack of information may have

been established by the conclusions drawn as to relative fighting

strength (Section I-B). If this be the case, notation of the fact is

made at this point in the commander's estimate of the enemy's

situation. If doubt exists as to the extent and accuracy of the

enemy's information, it will be desirable to credit the enemy with any

knowledge which it would be dangerous for the commander to conclude

was not available to his opponent.

In summarizing the enemy's situation, the commander may brief the

procedure by indicating those significant features of his own

situation, as summarized in Section I-A and as particularized in

Section I-B, which he does not consider are known to the enemy. The

commander will also indicate here any items of important information

as to which he has only a suggestion or an inkling, but which he

considers may be known in greater detail to the enemy.

(2) Analysis of the Effect Desired by the Enemy.

It may appear on first thought that the best basis for determining the

pertinent enemy courses of action is to make a deduction of the

enemy's mission. Sometimes, undoubtedly, this is the case. However, it

is not always possible to deduce the enemy's mission correctly. If the

deduction is incorrect the remainder of the estimate will be on an

unsound basis. If, as may happen, the enemy's plan has been captured,

or if, by some other method, conclusive information has been

obtained, it may be possible to state the enemy's mission. Even then,

however, the enemy's mission may sometimes be changed. It is thus

evident that the commander, by restricting his thought, may frequently

fail to consider all of the enemy capabilities which may materially

influence his own course of action.

With this precaution in mind, the commander, at this point in his

Estimate, proceeds to analyze the effect desired by the enemy. The

commander intends to use his deductions, if such use appears to be

sound, to narrow the field of consideration as to enemy courses of

action. However, he reminds himself that such restriction will be

dangerous unless it is established on sound grounds.

The first mental act toward determining the effect desired by the

enemy is to form a reasoned opinion as to the situation which the

enemy wishes to maintain or to create. The maintenance or creation of

this situation, existent or to be brought about, is an enemy

objective.

From earlier association with the enemy, from intelligence of his

peacetime preparations, and from a knowledge of his political and

military history, his broad current policies are generally matters of

common report. The motives impelling the enemy to action may thus be

evident. Past or present tendencies of the enemy, along certain

specific lines of endeavor, may be known. These may be corroborated by

the enemy action which has recently occurred.

In military undertakings of major scope the objectives of the enemy

are often difficult of concealment. A survey of the objectives which

the enemy has been pursuing may allow a reasoned opinion to be formed

as to the enemy's immediate objectives,--whether, at least, his future

action will be offensive or defensive. The importance to be attached

by the enemy to certain physical objectives may be indicated by the

broad aims known to exist. Present composition and disposition of the

enemy's forces may betray the effort which he intends. Circumstances,

clearly disadvantageous to the commander's forces, may disclose what

his enemy's aim may be for maintaining or creating a favorable (enemy)

military situation.

However scant or incomplete the data from such sources or from others,

the commander seeks to gain, by piecing together, a composite basis of

workable value in arriving at a sound conclusion as to the enemy's

future action.

The enemy objective thus visualized may serve as the purpose of the

enemy's mission. The situation thus envisaged may be specific or broad

in nature, depending on the soundness of the deductions. This, in

turn, will depend on the extent and character of the information

available.

It may now be possible to deduce a definite task, which when

accomplished, will attain the indicated purpose. However, as

previously stated, it is not desirable to be unduly specific. The

commander reflects on the several possibilities which if carried out

will attain the purpose. By being inclusive instead of restrictive in

this matter, he avoids the danger of overlooking enemy capabilities.

Moreover, the information available will not always justify the

derivation of a specific task.

By this process of reasoning, the commander may arrive at a studied

opinion as to the enemy's appropriate effect desired. The commander's

safeguard is that he has not been too restrictive or specific. He

expects to encompass within his conclusion the limits of the enemy's

objectives and actions, so that his own planned action will not fail

to cover all enemy action which can materially influence the

situation.

Situations may be encountered when, in the equation referred to in

Section II-B (page 135), no value can be assigned the factor of the

appropriate effect desired which will constitute a sufficient basis

for deducing enemy courses of action. Such situations are not unusual,

especially in problems of lesser scope. In such cases, the commander

is compelled to consider all possible enemy courses of action which

can materially influence his own plan. Therefore, in instances of this

nature, it is apparent that the procedure of giving first

consideration to the commander's own courses of action affords the

advantage of (see page 134) narrowing the field as to the enemy

capabilities.

B. Survey of Enemy Capabilities.

If, then (to repeat, because of the importance of the matter), the

commander believes that he has, in the deduced enemy effect desired, a

sufficient basis for evolving all pertinent enemy capabilities, he now

proceeds, by the mental process described in Section II, to list the

enemy courses of action which he thinks merit attention. If there be

no adequate basis, the commander will find it desirable to list all

enemy courses of action which can materially affect his own effort.

The survey of fighting strength (Section I-B) has established, through

consideration of the "means available and opposed", and of the

"characteristics of the theater", the limitations of enemy

capabilities from the standpoint of feasibility. Because, however, so

much of the enemy's situation is usually conjectural, it is important

to give the most searching attention to the comparison summary in

Section I-B,--in fact, to consider fully every element of weakness and

strength, and of advantage and disadvantage. Such a study will

disclose every possibility which the enemy might exploit. The

commander may thus determine, for example, the enemy strength which

can be moved into positions within time limits that can affect the

commander's courses of action; he can also examine into possibilities

of obtaining information concerning the enemy's moves.

Such a study enables the commander to envisage the enemy operations

which presumably can materially affect his own plans. He may now list

the presumed capabilities of the enemy, in the form of courses of

action, for purposes of further analysis. Naturally, he lists courses

which appear to be suitable, feasible, and acceptable as to

consequences, but formal tests are deferred until the next phase of

the estimate.

C. Application of Tests for Suitability, Feasibility, and

Acceptability.

Having listed pertinent enemy courses of action as described above,

the commander next tests them for suitability, for feasibility, and

for acceptability as to their consequences.

The procedure is the same as for his own courses of action (Section

II). However, since the enemy's appropriate effect desired, if

deducible at all, is often only an approximation, the test for

suitability is usually less rigid or absolute than for the commander's

own courses of action. By the same token, since the enemy's fighting

strength will usually include elements of conjecture and hypothesis,

the test for feasibility may be less reliable than when applied to the

commander's own courses. In fact, if there are any reasonable doubts

as to feasibility of an enemy course of action, it is properly

retained for further consideration. The same considerations and the

same safeguard apply with respect to acceptability of the

consequences.

D. Listing Retained Enemy Courses of Action.

All enemy courses of action which, after test, are retained for

further study are now listed by the commander.

While it is manifestly of advantage to the commander if the number of

enemy courses can reasonably be reduced to only a few or even to one,

it is important that no material enemy capability be neglected because

of undue restriction of the field.

The previous analysis will have indicated, at least, in some cases,

the degree of suitability and feasibility, and will have enabled the

commander to form a considered opinion as to any preference, from the

enemy viewpoint, on the basis of consequences as to costs.

In many instances, therefore, it will be possible to arrange retained

enemy courses in order of priority, i.e., the more likely being listed

before the less likely. In case of doubt, the higher priority is

awarded by the commander to enemy courses which are more dangerous

from his (the commander's) point of view.

In other instances, no priority can properly be indicated.

As a result of this study, the commander may now be able to combine

certain enemy courses. In any case, he closes this portion of the

estimate with a list of them, classified so far as he finds

justifiable, and thus made available for further effective use in the

estimate.

SECTION IV

SELECTION OF THE BEST COURSE OF ACTION

The extent to which detail is desirable in Section IV of the Estimate

will vary with the nature of the problem (page 95). Experience usually

demonstrates, however, that an estimate in only the necessary detail

escapes the danger inherent in undue detail which would tend to befog

the main issues. As the commander proceeds with his estimate, he will

recognize the need for additional examination into details, and will

conduct such examination accordingly.

A. Analysis and Comparison of Retained Courses of Action.

The next step in the estimate is the natural one of comparing the

commander's retained courses of action with those of the enemy which

have been retained for further study. This process consists of

executing, in imagination, the plan contained in each of the

commander's courses of action, against that in each of the enemy's.

One method is for the Commander to take the initiative with each of

his plans and mentally to push it through with vigor. By this

procedure, he concentrates his thought on the effect to be produced,

on the changed situation which that effect will bring about for the

enemy, on the modification in the enemy's effort which will be

caused, on the resulting obstacles which these modifications will

create, and on the provisions which will have to be made to overcome

the obstacles.

It will at once be apparent that the commander may have to re-estimate

the enemy situation during this analysis. Such necessity arises

because of the changes made by his own course of action upon the enemy

situation. The commander will desire to reach a studied conclusion as

to what counter action the enemy may take when the nature of the

planned action against him becomes evident. This re-estimate of the

situation may be brief, as it is an adjustment of factors which are

familiar through previous examination. Sometimes the re-estimate will

have been made mentally, before reaching this point, and adjustments

may already have been made in the written estimate, in anticipation of

this contingency. Sometimes the commander may find it desirable, after

reaching this point, to re-write, at least in part, his original enemy

estimate (Section III). The particular procedure adopted is

unimportant; the important feature is to recognize that such a

re-estimate process is normal, and especially so with reference to

this portion of the Estimate.

The foregoing discussion illustrates the point that an examination

into enemy capabilities is not complete if the commander puts himself

in the enemy's place merely for the purpose of estimating the original

situation from the enemy viewpoint. In addition, the commander

examines each of the enemy's modified problems which the changed

situation, created by the execution of the commander's plan, has

superimposed upon the enemy's original problem. Thus only can the

commander analyze the various ways whereby the enemy may oppose his

own proposed courses of action. Thus only may sound conclusion later

be reached, in the next subsection of the estimate, as to what course

of action, or combination of courses, is the best.

The comparison of plan against plan thus far has been restricted to

the method whereby the commander takes the initiative with each of his

own retained courses of action. Another method is to imagine the enemy

as taking the initiative, carrying through each of his courses against

each of the commander's courses. This method is applicable, for

instance, to cases where the enemy is able to initiate action which,

by its nature, would frustrate the execution of any of the commander's

courses. The choice of methods is a matter of judgment on the part of

the commander.

It is rarely that courses of action can be compared without resolving

each, to some extent, into the detailed operations which it comprises.

However, this analysis is confined, as previously explained (see page

145), to the details whose consideration is necessary for purposes of

a sound comparison. In some cases there may be need for study in the

greatest detail. Generally, however, the requirement can be met by

considering for each operation the kind of action, the types of

weapons, and the physical objectives.

During the progress of these analyses of the impact of operations upon

each other, there may occur to mind further operations which an alert

and awakened enemy may undertake in opposition; the counter to these

operations may also suggest itself.

The use of the chart, with positions and forces plotted, is here

frequently essential; in tactical problems diagrams and tables showing

possibilities of position, distance, speed, maneuver, gun ranges,

relative strength in types and weapons are useful.

* * * * *

Through the procedure described above, the commander is afforded

further opportunity to test his courses of action, as to suitability,

feasibility, and acceptability. He can, once more, view each of his

courses from the standpoint of its suitability. The visualized enemy

action may introduce considerations, not previously realized, as to

whether certain of his own courses are suitable to the appropriate

effect desired, when results are envisaged on the basis of the

possible opposition. As to feasibility, the analysis permits him to

make a further estimate of the enemy capabilities with respect to

obstructing or preventing the desired outcome of his (the commander's)

courses of action. In addition, by visualizing the pertinent

operations involved, he enables himself to evaluate the costs to be

expected.

Should the commander conclude, at this stage, that further

consideration of any of his courses, so far retained, is not

justified, he will naturally reject such courses so as to confine

further analysis within narrower limits.

Should he find, during his analysis, that further combinations should

be made among his retained courses, he makes such combinations and

uses them in his comparison.

However, he defers, until the next subsection, his choice of the

course to be finally selected, or his conclusion that none can

justifiably be adopted. The process of comparison is confined to

deduction, rearrangement, and justified rejection, preliminary to

weighing and selecting in the next subsection.

B. Determination of the Best Course of Action.

The commander is now ready to ponder over his retained courses of

action as further analyzed in the light of enemy opposition. All of

these courses, if carried out, are presumably competent, in varying

extent, to attain the appropriate effect desired. He will now examine

and consider them with the specific intent of coming to a conclusion

as to which one, or which combination, he will select as the best. The

analysis of each course of action in comparison with each enemy course

has made possible a comparison, to this end, of the commander's

retained courses with each other.

At this point, therefore, the commander again assembles his retained

courses of action.

He includes the combinations which the preceding analysis has

indicated belong properly together. He then considers the final

tabulation in the light of the considerations now to be noted.

The conclusive tests are now made for suitability, for feasibility,

and for acceptability as to consequences. Because of the importance of

this terminal analysis, it is desirable that the tests be as precise

as possible.

The commander now has, in addition to his list of the retained courses

of action, a summarized comparison of each with the others, under the

several pertinent headings. He next examines this all-inclusive

summary, with the intent of selecting the best course of action.

It may be found that one, or another, or a combination, is best.

Again, there is the possibility of considering, as best, a course of

action which, if carried out, will only complete an initial stage

toward the accomplishment of the motivating task.

If the result of the analysis has demonstrated that there is no

satisfactory course of action, this fact is here stated, with a

notation as to the reasons for such opinion. In this case the

commander faces a dilemma.

Usually a task imposed on the commander by higher authority will be a

carefully considered assignment of part of the superior's planned

effort. The commander may expect normally to find that his own

estimate of the situation will yield courses of action which, if

successfully carried out, will accomplish the task assigned. The

reasoned plan of the superior is a safeguard in this respect.

Nevertheless, realism requires that the commander be fully prepared to

meet the possible dilemma:--When he cannot envisage a course of action

for accomplishing the assigned task, or when, of the several courses

of action under consideration, he finds none satisfactory, what is he

to do? (See page 70).

Under these circumstances the commander reviews his estimate in all

its aspects. By minute re-examination he endeavors to find ways of

accomplishing his assigned task. If he cannot accomplish the task, he

seeks for ways whereby he can further such accomplishment so far as is

reasonably feasible. If unable, in any degree, to further the

accomplishment of his task, he endeavors to contribute, so far as he

feasibly and acceptably can, to the accomplishment of the purpose of

his mission.

It is to be expected, of course, that, if unable to accomplish his

assigned task, the commander will make constructive representations

(page 103) to higher authority. The latter may then assign additional

forces or may otherwise alter the problem,--for example, by assigning

a new task. However, a situation such as described may occur when the

commander is alone in a distant theater or when for other reasons he

finds himself unable to communicate, in time, with higher authority.

In such a situation the commander is under the necessity of

determining, for himself, a task which is suitable, feasible, and

acceptable under the circumstances (page 52).

It is evident that, at some point in the foregoing procedure, the

commander has been forced to abandon the solution of his basic

problem, because he has found that there is no sound solution. He has

not completely abandoned the solution of his original problem, because

he has not yet exhausted all of its possibilities. However, the

solution of the original problem has unquestionably entered a new

phase, or step.

The new step presents the commander with a new problem, a phase in the

solution of the original problem; the new problem is related to the

abandoned basic problem, because it arises out of the same situation,

which has not changed. The new problem is, however, differentiated

from the basic problem because it is based on a different incentive.

The incentive for the solution of the new problem arises directly out

of a decision made by the commander himself, i.e., his decision that

no sound solution for the basic problem can be found. The new problem

is one for the commander himself to solve, i.e., it cannot properly be

delegated to a subordinate for solution, because its solution is

necessary as a basis for the commander's detailed plan. For these

reasons the new problem is, by definition (page 106), a subsidiary

problem, of the type distinctive of the second step.

At what point in the solution of the original problem does the

commander abandon the basic problem and proceed with the solution of

the new, subsidiary problem which has arisen as described? There are

various possible answers, all with a basis of reason, to this

question.

From the standpoint of theoretical precision, it might be said that

the basic problem is abandoned when the conclusion is reached that its

motivating task cannot be accomplished. It might also be said that the

basic problem is abandoned when the conclusion is reached that the

commander can in no way contribute toward the accomplishment of the

motivating task.

Practical experience indicates, however, that the basic estimate can

profitably be utilized until the conclusion is reached that no

contribution can be made to the purpose of the mission. At this point

a new estimate, subsidiary to the basic estimate, necessarily begins.

This view is confirmed, theoretically, by the fact that, at this point

in the procedure, a radical change occurs with respect to the

appropriate effect desired. In such circumstances, the commander

concludes that he cannot contribute, in any degree, to the

accomplishment of his immediate superior's general plan.

The incentive for the solution of the subsidiary problem will

therefore arise, on the basis thus adopted, when the commander has

concluded that he cannot contribute to the accomplishment of his basic

mission, and that he is under the necessity of evolving a new mission

for himself. His basic Decision (see discussion, hereafter, of Section

V of the Estimate Form) will reflect this conclusion and will thereby

afford him a basis for the solution of his subsidiary problem.

Problems of the foregoing nature, where the commander justifiably

departs from his instructions, are not unusual during the first step.

However, they are scarcely typical of that step so long as an

organized chain of command is in effective operation. In the more

usual case, the commander, at this point in his estimate, makes note

of his selected course of action. Whether he selects a single course

or a combination, the selection is thereafter known as the best course

of action (singular).

SECTION V

THE DECISION

In the final section of the Estimate the commander is concerned with a

decision as to the selection of an objective or objectives determined

by himself, for the attainment of the appropriate effect desired. This

decision also indicates, in proper detail, the action to be taken for

the attainment of the commander's selected objective. The decision

reached at this point becomes the commander's general plan of action

or provides the basis therefor. It is accordingly so important that

when it has been formally stated in a basic problem it is thenceforth

known as the Decision.

The Statement of the Decision. Frequently the statement of the

Decision may be merely a restatement of the best course of action.

Such phraseology is often adequate, provided, naturally, that the

selected course of action has been, itself, correctly expressed (page

95). Sometimes, however, the commander may desire, at this point in

his estimate, to develop such expression more fully. He may at this

point develop his selected course into a general plan, or he may defer

this development to the second step.

In any event the commander now scrutinizes his selected course of

action to ensure that its expression conveys exactly the meaning which

he has in mind.

He bears in mind, also, that his Decision will settle the pattern of

his future action. If the selected objective is inferred, rather than

specifically stated, the commander will then ensure that the

inference, with all its vital implications, is plain.

As to the statement of the action required to achieve this objective,

the commander realizes that the pattern laid down by the Decision is

merely a shape or general outline. The details will be introduced

later. The Decision covers the general outline of the action

contemplated for the entire force.

If, for example, only a part of the commander's force is to act, while

the remainder is to remain inactive, the Decision will cover not only

the kind of activity but also the extent of the inactivity. However,

for convenience in stating the Decision, such inactivity may be

inferred, rather than expressly stated, so long as the meaning is

made clear. Thus, if the force, except for a raiding task group, is to

remain inactive for the time being, the Decision may properly be "to

raid enemy communications in the area ---- with a task group

consisting of ----", so long as the commander is satisfied that the

implication is clear, under the circumstances, that the remainder of

his force is to remain inactive.

The commander may properly include brief summarizing remarks as to the

methods, broadly viewed, whereby he intends to take action. However,

he introduces such detail only to the extent that he feels

amplification is needed, either for his own benefit or for the

assistance of others who may use his estimate.

Deductions or inferences which the commander wishes to note may, at

this point, be included with the Decision as corollaries (see next

page).

Where combinations of courses of action have been made in selecting

the best course, the meaning can sometimes be improved at this point

by modification of the previous wording.

When, as previously discussed (page 151), the commander has concluded

that he cannot feasibly or acceptably adopt any course of action which

will accomplish his task, contribute in any measure to its

accomplishment, or even contribute in any degree to the accomplishment

of the purpose of his mission, he records that fact in his Decision.

His study of the problem will by this time, however, have given him

the necessary data for a conclusion as to what his new mission should

be. He therefore closes his basic estimate with a Decision, coupled

with a purpose therefor, (see below), which will serve as a new

mission, i.e., as an appropriate effect desired. This provides a basis

for his solution of a subsidiary problem whose incentive is derived

from this Decision.

Of course, if the commander has had time and opportunity to represent

his situation on this basis to higher authority, and has received a

new task therefrom, the new task, coupled with the purpose also

indicated by higher authority, will provide the mission for the

solution of a new basic problem.

The Purpose of the Decision. The purpose of the Decision is identical

with the motivating task,--provided, of course, that the Decision, if

carried out, will accomplish that task in full. When stated, the

purpose is usually connected with the Decision by the words "in order

to".

If the commander has concluded that he will take action by stages, the

Decision may cover only the first stage. In all cases where the

Decision will only partially accomplish the motivating task,

appropriate words to link the Decision to its purpose may be such as

"to assist in" or "preparatory to".

The statement of this purpose, in connection with the Decision, is

frequently helpful and is sometimes necessary in making clear the

exact relationship between the Decision and the motivating task. In

the next planning step, where the detailed operations are determined,

this purpose is an important guide because each detailed operation is

expected to contribute to the accomplishment, not only of the

Decision, but also of the motivating task.

Corollaries to the Decision. The Decision may involve certain

deductions or inferences, either delimiting or amplifying its nature.

The commander may find it desirable to make note of these matters in

connection with his Decision. He may later wish to use these notes

when formulating his plan. Since these matters relate to deductions or

inferences which naturally follow as results of the Decision they are

properly referred to as "corollaries" to the Decision.

The nature of such corollaries may best be shown by an example. It is

supposed, for instance, that the commander has made the Decision "to

guard the Eastern Caribbean barrier against enemy penetration". During

the course of his estimate of the situation, he has come to the

conclusion that his operations to carry out this Decision will extend

into the area limited by Port X on the north, and Port Y on the south.

This conclusion is a deduction, which immediately assumes importance

when the Decision is made. The commander states this deduced

conclusion here, in connection with the Decision, for future guidance

in resolving the Decision into detailed operations, as well as for

later use in his directives to limit the action of his subordinates.

No particular form is specified for such corollaries. It is

satisfactory to list them as Corollary I, Corollary II, etc. They do

not constitute a part of the Decision.

Relation of the Decision to the Detailed Plan and Directives. The

Decision is the basis for the commander's plan of action for his

entire force. This plan is promulgated in one or more directives. The

Decision, as it appears in the Estimate, is not yet the concern of

subordinate commanders. It does not become their concern until it is

used in directives. As incorporated in the commander's detailed plan

and in his directives, the Decision, whether further developed or not,

constitutes the commander's general plan and is referred to in those

terms.

The Decision, as it appears in the Estimate, is not bound by any rigid

specifications as to form. Later (Chapter VII), when the commander

prepares for the inauguration of planned action by the formulation and

issue of directives, he assumes the obligation of conveying the

substance of his Decision to his subordinates in clear language. At

that time he will again have to subject its expression to scrutiny,

and may find that he has to make modifications solely for

clarification.

CHAPTER VII

THE RESOLUTION OF THE REQUIRED ACTION INTO DETAILED OPERATIONS

(The Second Step--The Solution of Subsidiary Problems)

The problem of the second step may be stated in question form

as follows: "What action should I take for the attainment of

my objective as selected in the first step?"

[Sidenote: For convenience a tabular form, inserted in the appendix,

page 224, gives page references to the principal subdivisions of this

Chapter.]

Having arrived at his basic Decision, the commander, if he wishes to

put it into effect, will proceed to formulate a plan of action which

can be cast into the forms of directives for execution. In making such

a plan, he provides for operations in the detail proper for his

situation. He thereby expands the general plan, indicated in or

developed from his basic Decision, into a complete plan which can

readily be placed in the Order Form (Chapter VIII) as a directive or

directives for the guidance of his subordinates.

The procedure involved in formulating such a detailed plan of action

has been described previously in general terms (Chapter V). The method

of determining the salient features of the operations required has

also been discussed (in Section III of Chapter IV). Therefore, these

matters are not repeated at this point.

The problems distinctive of this procedure (the second step, as

described in Chapter V) are subsidiary problems, in the sense that the

incentive for their solution arises by reason of a decision already

made by the commander, i.e., the basic Decision, and because they are

problems which the commander recognizes are to be solved by himself

and not by his subordinates.

Assumptions. The commander's plan has been derived from an estimate of

the situation based on the best information available to him. Complete

and accurate information is frequently lacking; hence, many military

plans consider contingencies which, to make a plan possible, have been

accepted in the estimate as assumptions.

The word assumption, when used to denote a basis for a plan, signifies

"the taking of something for granted". It does not mean a conjecture,

guess, or probability. The proposed action, resulting from a decision

made under an assumption, is designed to be taken only upon the

disclosure of the truth of the assumption. The fact that the

assumption upon which the plan is based may prove false indicates the

advisability of developing several plans based upon various sets of

assumptions.

It would be erroneous to believe that all contingencies can be

foreseen, and to be content with a particular set of plans, all of

which may prove to be wrong. It is not to be expected that a plan

based upon assumptions will, in all respects, be suitable for use in

an actual situation. For example, it will seldom occur that an

elaborate Battle Plan, based upon assumptions as to the various types,

dispositions, and strengths of forces present, the weather conditions,

and the intent of the enemy, can be used without changes.

On the other hand, a plan for the sortie of a fleet from a harbor

under assumptions that high visibility exists, that airplanes can

operate, and that hostile submarines will be the only force in

opposition, may frequently be found entirely applicable to the actual

situation, or so nearly so as to require only slight modification. It

is possible so to standardize such plans that only minor variables

need be indicated when the plan is to be used.

The visualization of valid and useful assumptions frequently makes the

most serious demands on professional knowledge and judgment.

Alternative Plans. The word "alternative" is generally applied to

contingent plans intended to accomplish a common task, but developed

from varying sets of assumptions. "A choice between several" is the

meaning of the word as here used. When such choice becomes necessary

in a situation not yet clarified, that plan will be selected which has

been derived from the set of assumptions considered by the commander

as most likely to be correct. The selected plan is usually called the

plan or the "accepted plan", and the other plans, coming from other

less likely but still possible sets of assumptions, are called

Alternative Plan No. 1, Alternative Plan No. 2, etc.

Naval tactical situations particularly lend themselves to the drawing

up of alternative plans in advance. There are numerous general

categories of such tactical plans. Among these the Battle Plan is of

paramount concern. Others include plans for sortie, entrance, defense

while cruising, etc. In each category, alternative plans may be

developed, based on various sets of assumptions.

Alternative plans evolved in advance of detailed information may be

found useful as a general basis for action. Circumstances may prove to

be different from those previously visualized. The correct procedure

is to keep the plans up to date, testing them, by the latest

information, in a Running Estimate (Chapter IX). The commander will

thus have a foundation for sound decision in the circumstances which

actually arise.

Still another use of alternative plans merits consideration. Early

coordinated action during actual operations may be demanded although

neither time nor the information available has permitted a detailed

estimate. If the commander has drawn up, in advance, plans based on

assumptions as to conditions that conceivably might exist, he will be

better able to appreciate the situations which actually arise. He can

thus direct the necessary action with more rapidity and understanding

than if completely unprepared because of lack of planning. If he

informs his subordinates of his proposed action under certain assumed

conditions, he will facilitate cooperation, because better mutual

understanding will exist. The advance alternative plans here discussed

are not necessarily confined to problems confronting a commander

during actual war operations. They may profitably be drawn up in

peace, and may be the basis of training exercises.

Application of the Essential Elements of a Favorable Military

Operation

In the solution of the problems distinctive of the second step, the

commander starts with a consideration of the salient features of a

favorably progressing military operation. This procedure is

appropriate because any series of these problems, considered as a

whole, pertains to the single problem of determining the most

effective operation, or series of operations, for carrying his basic

Decision into effect. If the action contemplated in the basic Decision

is of such a nature as to call for successive included efforts in more

than one stage, the commander limits his consideration, should he find

such restriction advisable on sound grounds, to the operation or

operations included in the first stage.

* * * * *

On this basis, the commander considers, first, the feature of correct

physical objectives. He has first to determine what his correct

physical objectives will be.

This determination may or may not present a perplexity. Frequently,

the procedure of the first step (Chapter VI) will have plainly

indicated one or more, perhaps all, of the physical objectives

involved. In some cases, also, the basic Decision will have plainly

pointed out the action to be taken, and with respect to what physical

objectives. In these instances, the commander may, with little further

analysis or none, set down the operations which he considers necessary

or desirable with respect to these physical objectives.

In other cases, however, the action indicated in the Decision, though

plainly indicating the commander's intent--that is, his calculated

line of endeavor--may not have designated the numerous physical

objectives as to which his effort is to be exerted. For example, the

Decision "to interrupt enemy trade on the southern maritime routes" is

quite clear, but what are the numerous exertions of force required,

and with relation to what physical objectives? Immediately there is a

perplexity. Guided by the analysis made in his previous estimate of

the situation, the commander now determines what the physical

objectives are, action as to which will contribute to the

accomplishment of the effort. The sum total of the actions taken

against these physical objectives is properly equivalent to the

accomplishment of the action indicated in his Decision. He may not be

able at this time to determine all of the correct physical objectives,

but he can determine certain correct ones (for the method, see Section

III of Chapter IV).

The correct physical objectives having been determined, so far as can

be done at this time, the commander studies each thoroughly,

developing the possibilities of certain effective actions (operations)

with reference thereto. For instance, in the case of a commander who

has been ordered to "interrupt enemy trade on the southern maritime

routes", he might develop one operation "to bomb enemy facilities at

Port X", and another "to capture or destroy enemy shipping along trade

routes" (with an indication of the routes involved).

The operations thus developed are now listed in a definite sequence,

in order to provide a proper basis for the further procedure. The

commander may find it desirable to state them in their order of

importance. Sometimes, however, it may be found advantageous to list

the operations in chronological sequence, i.e., in the order of their

execution. This point is further discussed hereafter (pages 166 and

192). The commander is at liberty, of course, to use either method

according to its helpfulness in enabling him to visualize the elements

of his problem.

* * * * *

The commander now considers the second feature: advantageous relative

positions. He may already occupy an advantageous geographical location

or locations (see pages 64 (bottom) and 65 (top)), or he may desire to

improve his positions in certain respects. An advantageous position

might be between the enemy and his base, in order to deny it to him.

Another advantageous position might be to windward of the enemy, for

the purpose of making a destroyer attack under the protection of a

smoke screen.

The commander now reconsiders, from the viewpoint of "advantageous

relative positions", the operations deduced with respect to "correct

physical objectives". As a result of this reconsideration, he may find

that certain of these operations may be retained without change,

whereas others may require modification.

Suppose, for example, that two of the operations listed are those

noted above, viz:

"To bomb enemy facilities at Port X", and

"To capture or destroy enemy shipping along trade routes

between the ---- parallels of north latitude and the

---- meridians of west longitude."

From the viewpoint of relative position, it may appear that the first

operation is not affected seriously, if at all. Therefore, this

operation may be left unchanged. However, the second operation may be

definitely affected by relative position, because the best method of

interrupting enemy trade may be to employ raiding forces in focal

areas. Therefore this operation might be altered to the form, "to

capture or destroy enemy trade by raiding focal areas" (with a

designation of the areas).

The commander's study is now likely to suggest operations which were

not apparent when the analysis was confined to the correct physical

objectives, alone. New physical objectives may appear to require

attention. If so, all such new operations are added to the list

compiled.

* * * * *

The commander may now study his list of operations, compiled to this

point, from the standpoint of the third feature, proper apportionment of

fighting strength. However, if the commander considers such apportionment

now, his subsequent study of the fourth element--"adequate freedom of

action"--may develop a need for further operations which will in turn

call for a re-analysis as to his apportionment of fighting strength.

Therefore, for purposes of this discussion, it is assumed that the

commander now defers consideration of such apportionment, and that

he proceeds at this point to study measures for ensuring adequate

freedom of action.

This study requires consideration of such matters as training, morale,

surprise, secrecy, cooperation, intelligence, logistics, and

provisions (communications, location of the commander, and the like)

for effective exercise of command. (See page 76). The commander

exercises his judgment as to the degree of detail in which such

matters should be treated, according to the nature of his problems.

If any such subject--for example, communications--involves the

development of a subsidiary plan (page 168), the measures noted in

connection with the formulation of the basic plan may be stated along

broad lines, such as: "To provide for effective communications." Any

specific matters of considerable importance may also be included,--for

example, as to secrecy with respect to the use of communications.

Other details may then be deferred until the commander takes up the

necessary subsidiary plan. Otherwise, all pertinent operations in

connection with these measures are naturally noted at this point.

Certain of these measures for freedom of action are now to be

discussed in some detail because of their important bearing on basic

plans.

In certain operations contemplated by the commander, there may be a

requirement for additional training, sometimes of a special nature.

This may be true, for instance, if an operation involves the landing

of an expeditionary force. Conditions permitting, the commander will

naturally desire to make provision for training exercises. If time or

other conditions do not permit necessary training, he may find it

desirable to modify his plans accordingly. The salient features of a

subsidiary training problem are discussed hereafter (page 176), and

may well be considered at this point in developing the basic plan.

The commander may already have noted, in considering operations

suggested by his previous study of the situation, a need for certain

action as to security, secrecy, and intelligence. Any additional

operations of this nature, not previously noted, may well be

incorporated at this point.

Security of his own plan, and secrecy therefor, are important

considerations with reference to intelligence activities. The

requirements as to intelligence and counter-intelligence features are

primary considerations as to any plan. Such considerations involve the

collection of information and its conversion into intelligence. The

hampering of enemy intelligence activities is a related consideration.

The collection of useful information, and its denial to the enemy,

call for a definite plan. When information has been collected, it is

subjected to the processes (page 122) of analysis, evaluation,

interpretation, and dissemination. Collection, to be consistently

effective, calls for specific directives to, or requests on, the

appropriate collecting agencies. Analysis determines the source of the

information and the circumstances under which it was obtained.

Evaluation determines its degree of reliability. Interpretation

consists of drawing conclusions; when information thus takes the form

of facts (so far as they can be ascertained) and of sound conclusions

drawn therefrom, it becomes military (naval) intelligence. It is then

disseminated to those concerned and is used in the solution of the

commander's own problems.

The basis for collection of such data is the determination of the

essential elements of information desired by the commander. The

notation of these essential elements, for later incorporation in his

directive(s), naturally constitutes a primary feature of his basic

plan. The essential elements of information are frequently formulated

as questions--e.g., Will the enemy do this? Is the enemy doing that?

What are the principal topographic features of Y Island, with respect

to so and so?

These questions cover the essential matters of perplexity as to enemy

courses of action and as to the characteristics of the theater. Each

enemy course of action, for example, may provide the basis for a

question; or, if the scope of the problem has narrowed sufficiently,

such question may deal with one of the enemy's possible operations,

related to a course of action which he may be pursuing or is known to

be pursuing.

On the basis of the essential elements of information, the commander

provides for proper reconnaissance activities by the several

collecting agencies under his command, or for appropriate requests to

be made by him on other collecting agencies. A sound plan will always

make adequate provision for such measures.

These subjects are treated in more detail in the later discussion

(page 177) of intelligence problems.

* * * * *

In connection with freedom of action, the commander will also make

adequate provision for logistics support. In its unrestricted sense,

the term "logistics" relates to the supply and movement of a military

force, and to such related matters as the disposition and replacement

of ineffective personnel. Logistics measures, as comprehended in the

development of the basic plan, exclude movement primarily of a

strategical or tactical nature, but include movement related primarily

to supply and similar matters. This requirement gives rise to the

necessity for logistics measures which may further call for operations

such as to provide fuel oil and supplies at rendezvous X and Y, and

tender facilities at port D. An incidental requirement will relate to

movements of train ships. Hence, the commander formulates these, also,

and includes them in his list of operations for later assignment as

logistics tasks. (Page 166). Fuel oil may likewise be required at Port

D, but if the commander knows that ample fuel oil is in store there,

no operation to cover this feature is required of him.

The solution of logistics problems is further discussed hereafter

(page 179).

* * * * *

The commander has now, it may be presumed, evolved all of the

operations that his analysis tells him are appropriate with respect to

correct physical objectives, advantageous relative positions, and

freedom of action. Therefore, he now studies all of these operations

from the viewpoint of the remaining element--proper apportionment of

fighting strength. This consideration involves, initially, a

determination of what forces will be necessary to carry out the

operations listed. The commander thereby determines the requirements,

as to forces, for each such operation.

For example, the operation "to locate an enemy force" may require the

use of several types of naval vessels and aircraft. The commander

determines what method of search is best for the purposes of this

specific operation; thereafter, he determines what forces are

necessary to conduct the search. The procedure has previously been

indicated (in the Principle of the Proper Means to be Made

Available--page 34).

In this study the commander will often find it necessary to divide

some of the more extensive operations into component parts, suitable

for later assignment as tasks for subordinates. Fundamentally, there

is no difference between an operation and a task, except that the

latter includes also the idea of imposing on another person, or

assigning to him, a definite amount of work or duty (page 84). At this

stage, then, the commander deals with components suitable for

performance by available weapons, in the usual units, or combinations

of units, in which they are effective. Of course, when an operation

meets this requirement without subdivision into components, it need

not be subdivided.

These component parts are not yet actually tasks, because the

commander does not plan to assign them at this time to any one for

execution. However, the components are visualized as clearly, and are

formulated as definitely, as is possible at this point. The

requirement is that they be acts that available forces can perform.

The method of breaking down an operation into component parts is one

of analysis and deduction. Having visualized the manner whereby the

operation can contribute to the accomplishment of the effort, the

commander has now to determine the means to be employed to this end.

Experience and knowledge tell him what numbers and types of ships,

aircraft, and other weapons, if properly employed, will attain the

effect desired.

Each component part will indicate both the action and the physical

objectives of the action. For each component, the commander estimates

what forces are required. He knows the extent of the armed forces

available, and he can, if his total force is adequate, adjust matters

to allow each component a force capable of carrying it out.

For example, a component operation might call for a search by

destroyers, but the commander might find that his destroyers were in

such poor relative position as to prevent them from reaching the point

of origin in time. Therefore he would be unable to conduct the search

by using destroyers alone. He might now consider a search by aircraft.

A study of this proposal might indicate that it could be carried out

in part by aircraft, but that available aircraft were inadequate to

carry it out in its entirety. In such event, consideration would be in

order of the possibility of conducting this search by use of other

forces also, e.g., submarines and cruisers.

In case the commander believes an indicated operation to be

infeasible, he first restudies that operation to see whether he can

modify it, without adversely affecting the accomplishment of the

effort. He may even find that he can eliminate it by including its

essential features in some other operation.

If the commander finds that his forces are inadequate for the

accomplishment of an effort in one stage, but that they are adequate

for its accomplishment in successive stages, he may draw a conclusion

as to which of the operations he can carry out first. On this basis,

he may proceed with the formulation of tasks to include these

operations, leaving the remainder to a future time (see page 56).

It may be that all operations set down cannot be accomplished by the

forces available, but that they will be possible of accomplishment if

other forces are provided. This knowledge, of the sum total of forces

required for the action indicated in the Decision, is an essential. It

is only by such a searching inquiry that the commander ensures that

the operations resolved from the Decision will result in a full

solution of his problem. Usually the forces available will be found

adequate, because the superior who provided them gave consideration,

on his part, to the requirements. However, if the forces available are

not deemed adequate, the commander either modifies the operations, or

restricts them, or subdivides them into parts for performance in

succession by stages. In any such case, conditions permitting, he

makes constructive representations, together with a report of the

facts, to his superior (see page 103).

Testing for Suitability, Feasibility, and Acceptability.

Each of the operations finally deemed necessary or desirable is now

tested as to its suitability, its feasibility, and its acceptability

as to consequences. The considerations involved have been explained

previously (Section III of Chapter IV) and are therefore not repeated

here.

The testing process will eliminate those operations found not

suitable, feasible, or acceptable.

In addition, the tests may lead to the elimination of operations

which, while both suitable and feasible, do not contribute enough

toward the accomplishment of the effort to warrant their retention.

For example, among the operations listed might be one to capture X

island and one to capture Y island, both suitable and feasible. The

commander, having analyzed these proposals, might conclude that the

capture of Y island would not constitute a sufficient contribution to

warrant its adoption as an operation at this time. Therefore, he might

omit this operation, or he might defer it to a later stage.

A feasible operation may similarly be rejected or deferred out of

preference for another which can more readily be accomplished.

The tests may also reveal important facts as to the relative

consequences with respect to costs. For example, two operations might

both be acceptable as to this factor, but one might be less acceptable

than the other. Accordingly, the less acceptable operation might be

omitted, or might be deferred for the time being.

Upon the completion of the tests, all operations retained are listed

for further development.

The Formulation of Tasks

The correct resolution of the Decision into the detailed operations

required is further ensured by the visualization of these operations

as tasks. Tasks so formulated (page 162), become a basis for the

preparation of directives.

To prepare a plan as a basis for directives, or for use as such, the

commander first finds it desirable to formulate and assemble the

various tasks. The tasks are formulated as a result of his study of

(1) those operations which do not require to be broken down, and which

may now be rewritten as tasks, and of (2) the component parts of the

more extensive operations (See page 162, bottom).

Each of the tasks, as now listed, is tested for suitability, for

feasibility, and for acceptability with respect to the consequences as

to costs. In view of the fact that the operations have all been

thoroughly tested, this process now becomes not a formal analysis but

merely a check.

The Organization of Task Forces and Task Groups

The commander now classifies the tasks on the basis of their

suitability for accomplishment by appropriate task forces or

subdivisions thereof, i.e., task groups. In so doing he endeavors to

avoid forming any more classifications than are necessary for the

accomplishment of the full effort.

Note: In the remainder of this work, the term Task Group, except as

may otherwise be indicated, will be understood in the inclusive sense

of either "task force" or "task group".

Tasks are assigned to task groups on the basis of such factors as the

nature and geographical location of physical objectives, the existing

disposition of the several units, their capabilities, and their

freedom of action. The last-named may be the determinant, and,

because of the importance of such considerations, tasks which would

otherwise fall to one group might be assigned to another. Features

influencing a change might include lack of training of the personnel

available in the first group, or the special qualifications of a

particular commander, or a justified desire to adhere to a previously

determined permanent task organization.

Logistics tasks, i.e., those requiring operations for placing

logistics measures in effect, require the same careful consideration

as do combat tasks. (See page 162).

Certain tasks apply to all of the task groups, or pertain to the

general conduct of the common effort. Among such may be provision for

security, for unity among the subdivisions, and for intelligence

activities (page 160). In order to avoid repetition, these tasks are

assembled in one group.

The commander analyzes the requirements of fighting strength for each

task group. He then, from the means available to him, assigns the

necessary strength to each group, making adjustment between the

theoretical requirements and the actual strength available.

He is familiar with the types of vessels and aircraft constituting his

command, and with their military characteristics; with the

capabilities and cooperative qualities of his commanders; with the

degree of training of his various units; and with the geographical

location of physical objectives. He recognizes that each task requires

adequate strength for its accomplishment. Because these requirements

have been thoroughly considered during the study of the effective

apportionment of fighting strength, he is able to make adjustments as

necessary.

The commander now fully organizes each classification of tasks and its

corresponding task group by naming the task group (or task force), by

making notation of its composition and of the rank and name of its

commander, and then by listing the tasks of each group. The principal

task (or tasks) may be listed first, the other tasks following in the

order of their importance. If preferred, the sequence of tasks may be

chronological. Also, either major or minor tasks may be listed

chronologically. (See pages 158 and 192).

If the chronological sequence of tasks is utilized, that fact, in

order to avoid confusion, is clearly indicated.

Thus organized, the whole plan can be transferred almost bodily into

the Order Form (Chapter VIII).

Application of the Fundamental Military Principle to the Determination

of Objectives Embodied in Tasks

In formulating tasks for the several task groups, the commander has

now visualized, for each such group, an objective (or objectives) for

the subordinate to attain. In selecting these objectives, the

commander has placed himself, mentally, in the subordinate's

situation, visualizing the problem which the subordinate is to solve.

On this basis the commander has apportioned the strength needed for

the attainment of the objectives assigned to his subordinates. This

procedure, of evident importance, is frequently one of considerable

difficulty, because a higher commander, lacking detailed information

of the situation which may confront a subordinate cannot always

anticipate all the obstacles to the latter's success.

In formulating tasks, and in apportioning strength, by the procedure

already described, the commander has applied the Fundamental Military

Principle. Now, to ensure the practical adjustment of means to ends

(page 66), the commander reviews the process in the light of that

Principle, so that he may be assured that he has selected a correct

objective (or objectives) for each subordinate. By using the tests

indicated in the Principle, the commander confirms the suitability of

each objective so selected, satisfies himself of its feasibility of

attainment, and assures himself that the costs involved will be

acceptable. If these requirements cannot be so satisfied, necessary

adjustments are in order.

These tests may frequently be of a routine nature, by reason of the

previous painstaking tests of the several operations involved.

However, such final tests cannot be omitted without incurring the

danger of selecting incorrect objectives for subordinates to attain.

The Assembly of Measures for Freedom of Action

Having completed the classification of his tasks, the commander next

assembles the measures determined upon as necessary for ensuring

adequate freedom of action.

When the subject matter is not too bulky, these measures are

incorporated in their proper place in the basic plan. Otherwise,

instructions as to these matters will be issued as annexes.

The various measures are assembled under the classification shown

below:

(a) Measures required for security, for cooperation, and for

intelligence activities.

(b) Measures for logistics support. These cover provision for

procurement and replenishment of supplies, disposition and

replacement of ineffective personnel, satisfactory

material maintenance, sanitation, battle casualties, and

the like.

(c) Measures for the exercise of command. These include

provision for communications, location of rendezvous, zone

time to be used, and the location of the commander.

This classification corresponds to that used in the Order Form (page

193). Experience has indicated that such a classification facilitates

the transmission of instructions to subordinate commanders.

If desired, the material which will be required to be incorporated in

paragraph (1) of the Order Form (see pages 190, 191, 219 and 221) may

be also assembled at this point.

The Preparation of Subsidiary Plans

As previously noted (page 106), certain subsidiary problems require

the preparation of subsidiary plans to be included with the directive

as annexes. In broad strategical estimates, the solution of such

subsidiary problems involves a vast amount of mental effort; even in

restricted estimates, these problems may require most intensive

thought. It is therefore appropriate at this point to discuss, in some

detail, the nature of these subsidiary problems.

During the solution of his basic problem and later, during the process

of evolving his basic plan, the commander may become aware of the need

for further action of a supporting nature with respect to his basic

mission, distinct from that which he intends to assign as tasks to

subordinate commanders. If the nature of this action involves

perplexity, he will be confronted with new problems to be solved. When

he recognizes that such problems exist and are to be solved by

himself, this awareness is a recognition of the incentive.

For example, one of these problems may involve a battle in which the

entire force will participate, or perhaps a sortie requiring

coordination of the several subdivisions of his force. Others will be

concerned with measures recognized as necessary for ensuring freedom

of action.

These problems give rise to the subsidiary plans previously referred

to (page 106). They are not necessarily subsidiary in importance; even

the Battle Plan, the basis for the culmination of tactical effort, may

result from the solution of a subsidiary problem. The word

"subsidiary", as here used, merely indicates that the problem has its

origin in the commander's own Decision.

When the incentive is thus recognized during the solution of the

basic problem or during the second step, the commander solves these

new problems, and includes their solutions as a part of the directives

prepared for the carrying out of the basic plan. As will be seen later

(Chapter VIII), there is a prescribed place for such solutions in the

usual form in which directives are issued. Often, however, because of

extent and bulk, these solutions are included with the directives as

annexes.

The commander will desire to provide for all contingencies, but he can

rarely, during the planning stage, see completely into the future, so

as to foretell all pertinent events which may befall. During the

unfolding of events, therefore, unforeseen subsidiary problems will

probably arise. Whether visualized during planning, or encountered

during the execution of the plan, these problems have the same

relationship with the basic problem. Reference is later made (Chapter

IX) to subsidiary problems which arise during the action.

Subsidiary problems, according to their nature in each case, may be

solved by the procedure distinctive of the first step or by that

distinctive of the second. In many instances either may be applicable,

the choice being a matter of convenience.

Battle Plans, for example, can demonstrably be formulated by the use

of either procedure. Thus, a Decision "to destroy the enemy in a

daylight fleet engagement" may be used as the basis for an Estimate of

the Situation, by the procedure distinctive of the first step, in

order to reach a decision as to the plan, in outline, for the

contemplated engagement. However, the same result can also be attained

through the procedure distinctive of the second step, with the basic

Decision as the point of departure.

A solution also can be reached by a method which is, in effect,

intermediate between the procedures of the first and second steps. For

example, the basic (broad strategical) Decision noted above can be

taken, in a detailed tactical Estimate, as the only suitable,

feasible, and acceptable course of action. Then, in Section IV of the

Estimate, a study of the more detailed operations involved can be

developed into an outlined plan for the battle. Thus, a single course

of action, expanded to include the outlined plan so developed, can

then be adopted as the decision and can in turn be expanded by

second-step methods into a detailed tactical plan.

On the grounds of simplicity, the procedure distinctive of the second

step is preferable, when it is applicable to the particular problem.

Therefore, when a subsidiary plan is to be developed directly from a

basic Decision, this is frequently the better procedure. This comment

is applicable not only to battle plans but also to other subsidiary

plans such as sortie plans, entrance plans, and logistics plans. The

commander may find it necessary, however, to expand the study of

fighting strength made in Section I-B of the basic estimate, in order

to obtain the detailed data needed for formulating the subsidiary

plan.

In spite of the relative simplicity of the second-step method, cases

occur where the procedure of the first step is nevertheless

preferable. For example, a basic Decision making provision for a major

campaign, divided into stages of some scope, may involve, as part of

one of these stages, an operation to capture an island. Such an

operation may itself require a considerable effort on the part of the

whole force; yet the operation may be so specialized or localized, or

both, with reference to the entire effort contemplated in the basic

Decision, that the solution of this subsidiary problem can best be

accomplished through the procedure distinctive of the first step.

The commander will therefore necessarily be the judge, in each case,

as to the particular procedure to be adopted.

There are wide variations in the requirements of the Estimate Form,

when used for the solution of subsidiary problems. This is natural

because these problems vary widely in nature. They include, on the one

hand, problems dealing directly with the conflict of armed forces, for

which the Form is especially designed. On the other hand, these

problems include those dealing with the factors related to freedom of

action. To be suitable for this purpose, the Form requires

modification in varying degrees. Certain examples are included in the

latter part of this chapter (page 176 and following).

The application of the procedure of the first step to the solution of

such subsidiary problems requires provision for deriving, in each

case, a (subsidiary) mission appropriate to the problem. Of the two

elements of the mission, the (subsidiary) purpose is first determined,

because the (subsidiary) task will necessarily be suitable to the

(subsidiary) purpose. These elements of the (subsidiary) mission may

be obtained from one or more of the operations into which the basic

Decision has been resolved. They may also be obtained from a preceding

subsidiary problem, already solved.

In illustration of the preceding, discussion is first centered on a

strategical problem of usual type, involving a subsidiary tactical

problem calling for the detailed employment of weapons in a naval

engagement. Other illustrations will deal with subsidiary problems

relating to particular aspects of freedom of action.

In the first example it is supposed that the commander has already

solved a basic problem of broad strategical scope, and has arrived at

a Decision which contemplates an engagement. A further logical act of

planning is now to develop a Battle Plan. Such development involves

the solution of a subsidiary problem. In this case the commander is

supposed to have found it desirable to solve this subsidiary problem

by the procedure distinctive of the first step.

In this problem, the situation summarized is an imaginary one. It may

eventuate either through the natural future developments of the

situation existing at the time of the solution of the basic problem,

or it may confront the commander during the execution of the plans

derived from the Decision of that (basic) problem. The Battle Plan

finally to be formulated will be for use under the conditions assumed

in this situation.

The commander will desire to draw up a Battle Plan as a provision for

the situation which he believes most likely to eventuate. However, as

he cannot be certain that this situation will occur, he may also

desire to assume other situations, i.e., prepare in advance for other

contingencies. It is then necessary for him to solve several problems,

each differing from the others in the assumptions (page 155) as to the

form the situation may take. The summary of the situation therefore

requires a brief statement of the conditions which are assumed. In

addition, such parts of the basic problem may be included as are

deemed pertinent to the new problem in hand.

In his new problem the purpose of the (subsidiary) mission may readily

be obtained from the basic problem. Suppose the assigned task,

motivating the estimate of the basic problem, to have been to "prevent

enemy convoy from reaching destination". This, the motivating task of

the basic problem, then becomes a suitable (subsidiary) purpose for

the mission of the subsidiary problem.

For the mission of the subsidiary problem, a motivating task, suitable

to the purpose thus determined, will be found in the Decision of the

basic problem. Suppose the Decision in this case to have been "to

destroy the enemy convoy". The task thus determined for the subsidiary

problem becomes an assigned task in the sense that it is assigned by

the commander to himself, instead of to a subordinate; however, it is

also an assigned task in the sense that it has been indirectly

assigned by the immediate superior, because it has been derived, in

the basic estimate, from the motivating task which was directly

assigned by the superior.

The two elements, of task and purpose, when linked together, enable

the commander to visualize the appropriate effect desired, as the

basis for his subsidiary estimate,--a procedure identical with that

followed in a basic estimate. As in the latter, the commander can now

formulate his subsidiary mission, as:--

(Task) To destroy the enemy convoy,

(Purpose) in order to prevent it from reaching its

destination.

The mission of the subsidiary problem is thus seen to be identical

with the basic Decision linked to the purpose of that Decision.

However, this is not always the case. A subsidiary problem may merely

involve the execution by the commander, i.e., under his own immediate

direction, of a designated part of his general plan. Or, such a

problem may involve execution, by the commander, of one or more of the

detailed operations for the accomplishment of his general plan or of a

part thereof. The commander may also find it necessary to solve

numerous subsidiary problems of relatively restricted scope pertaining

either to his general plan or to a part thereof or to the detailed

operations involved.

In some of these cases the purpose of the subsidiary mission may be

readily apparent. In others, its nature may become clear only after

the application of considerable mental effort. In every case the

determination of a proper (subsidiary) purpose involves visualization

of a situation which the commander desires to bring about or to

maintain. The (subsidiary) task, appropriate to the (subsidiary)

purpose, will always necessarily be suitable to the latter. This task

is then the motivating task for the solution of the particular

subsidiary problem in hand. This will be the case whether the

commander makes a simple mental solution or produces a more complex

one in which the formal written estimate of the situation is employed.

In the former instance, the brevity of the mental process tends to

obscure this fact.

An example might occur in a situation where the commander has received

an order to "Protect the base at A". It is then supposed that, after

estimating the situation, he has reached the Decision "to deny the

enemy the use of base sites within effective bombing range of A", the

purpose of the Decision being, of course, "in order to protect the

base at A". The action required might then be undertaken in two

stages. The first stage might be confined to the area ABCD. If, then,

all available base sites in this area, except Y island, were already

securely in friendly hands, the commander would find it necessary to

make provision for an operation to deny the use of this island to the

enemy. If this operation is of such a nature that the commander

desires to execute it under his own direct control, instead of

assigning it to a subordinate, it presents a subsidiary problem which

the commander, himself, has to solve.

The commander has now determined the necessity of solving a subsidiary

problem relating to the accomplishment of a designated part of his

general plan. He has also determined the necessity of solving another

subsidiary problem presented by an operation pertaining to the first

stage of the accomplishment of his general plan.

Each subsidiary problem requires an estimate of the situation although

"the brevity of the mental process tends to obscure this fact" (page

172).

In making his basic estimate, the commander may have discovered the

need for these subsidiary estimates. In this case, he may have

included them in his estimate, as "estimates within the estimate"

(page 83), in his analysis of the operations involved in the various

courses of action which he considered. For instance, his basic

Decision may have included the capture of Y island, and he may have

covered this feature by a corollary to that Decision, as follows:

Corollary: As a first stage, to deny the enemy the use of

available base sites in the area ABCD, by capturing Y island.

However, the commander may not discover the desirability or need of

solving these subsidiary problems until the second step, when

resolving the basic Decision into the detailed operations required. In

this case, he might make due provision at that time for the operations

involved in the subsidiary problems. The mental procedure would be the

same in either event.

The commander may find, however, that he prefers to make a separate,

subsidiary estimate with respect to the determination of the stages of

his operation, including the details as to the performance of the

first stage. In this case he finds a proper mission for his subsidiary

estimate in the basic Decision, linked to its purpose. This mission

would be as follows:--

(Task) To deny the enemy the use of base sites within

effective bombing range of A,

(Purpose) in order to protect the base at A.

During the subsidiary estimate the commander may discover, in his

study of the area ABCD, the necessity for an operation to deny Y

island to the enemy, and may even go so far, in this study, as to

decide on the capture of this island. The decision, settling on this

area as the scene of the first stage of his effort, may then include

provision for the capture of the island, as follows:

Decision: To deny the enemy the use of base sites in the area

ABCD as a first stage toward denying him the use of all base

sites within effective bombing range of the base at A.

Corollary: To capture Y island.

However, the commander may not take up the matter of denying Y island,

specifically, to enemy use until he studies the detailed operations

required for the accomplishment of the action involved in his first

stage. In such event, he may make provision for the capture of the

island in his subsidiary plan for the execution of the first stage. He

may find, on the other hand, that he prefers to make a separate,

subsidiary estimate as to this feature. If so, the mission for this

subsidiary estimate would be identical with the decision (less the

corollary, but plus the purpose of the estimate), i.e.,--

(Task) To deny the enemy the use of base sites within

effective bombing range of the area ABCD as a first stage

(Purpose) toward denying him the use of all base sites within

effective bombing range of the base at A.

During this estimate the commander considers the various courses of

action whereby he can deny to the enemy all bases in the area of the

first stage. Concluding that Y island is the only base site not

securely in friendly hands, and that the best method of denying it to

the enemy is to capture it himself, he reaches a decision as follows:

Decision: To capture Y island, in order to deny to the enemy

the use of the only available base site in the area ABCD.

In each of the foregoing cases, the commander is said to have

"deduced" the mission for his subsidiary problem. As has been

demonstrated, the process of deduction is merely the application of

the natural mental processes through the use of the estimate of the

situation. Whether the estimate is formal or informal, detailed or

brief, written or mental, is immaterial; in any case, the estimate

results in a decision which provides, with its purpose, a proper

mission for the succeeding problem which has been presented by

solution of its predecessors.

In logical sequence, from problem to problem, the procedure outlined

in the preceding discussion enables the commander to derive a correct

mission for the problem involving the capture of Y Island. Clear

visualization of such a subsidiary mission is frequently of great

importance, and may be difficult unless the procedure has been

carefully traced from each problem to the next. In this particular

example, if the commander finds that the capture of Y Island is of

such a specialized and localized nature (page 170) as to call for a

formal estimate (as may frequently be the case in capturing a

well-defended island base), he will be especially desirious of

deriving a correct (subsidiary) mission as a basis for this estimate.

In this instance a correct mission would be:--

(Task) To capture Y Island,

(Purpose) in order to deny to the enemy the use of the only

available base site in the area ABCD.

This mission is identical with the decision, linked to its purpose, of

the preceding subsidiary problem.

Subsidiary problems relating to training (page 160), when solved by

the procedure distinctive of the first step, involve estimates of the

situation very similar to those explained previously (Chapter VI).

Section I-A of such a training estimate will include a summary of the

salient features of the existing situation, from the strategical or

tactical viewpoint, together with a statement of the salient features

of the operations to be carried out for which the projected training

is designed. The incentive will be found in a previous decision

calling for the operations which require the training to be given. The

assigned objective will be the making of adequate provision for

training appropriate to the projected operations. The (subsidiary)

mission will be:--

(Task) to provide appropriate training,

(Purpose) in order to contribute to freedom of action during

the operations contemplated. (In each particular case the

operations contemplated will be indicated by proper

phraseology in the mission or by reference to the preceding

summary of the situation.)

Section I-B of a training estimate will take account of the training

factors cited in the Estimate Form (Chapter VI) for a basic problem,

but will specify details with respect to both own and enemy forces.

This section will also cover existing facilities for training, as well

as the characteristics of the theater which have now or may have a

bearing on the training to be given.
