_Introduction_
Terrain Exercises are those military exercises in which the students
carry on the operations of imaginary bodies of troops over the actual
terrain. As these exercises involve the study of the utilization of the
ground itself and the application of tactical formations and methods to
it, they are the best means, aside from practical field work with
troops, of giving officers and non-commissioned officers practice in
carrying out the duties that fall to them in war.
In the Terrain Exercise is found the logical step in tactical training,
between the theory and practice of the classroom and the practical
training with troops. This method of training is suited to all arms and
services, and in view of its practical value is constantly employed by
unit commanders in the training of their officers and non-commissioned
officers.
Any class of military operations may be practiced, such as the
operations of covering troops—advance guards, flank guards and outposts;
the operations of the various kinds of patrols; combat—attack and
defense; approach march and deployment, and the tactical cooperation of
all special arms.
