=Situation No. 7=:
It is assumed that the advance guard has been marching for two hours
since the march was resumed after the enemy patrol was encountered.
During this time enemy scouts have been observed from time to time, but
they have not attempted to interfere with the march of the column.
You, Captain A, are marching at the head of the support. When you arrive
at this point the signal “HALT” is received from the rear. You halt and
relay the signal forward. A moment later the battalion adjutant joins
you and states: “The column will halt for one hour. The major directs
that the advance guard provide for the security of the command for that
time.”
_Required_:
What action do you, Captain A, take?
