FACE, 3. Forward, 4. MARCH, 5. Guard, 6. HALT,
7. Right (or left), 8. FACE.=

The left or right half only of the guard as indicated, executes the
movement. (101)

=1664.= If there be but few prisoners, the sergeant may indicate the
point of division as above, and form the necessary interval by the
commands:

=1. Right (or left) step, 2. MARCH, 3. Guard, 4. HALT=, and close the
intervals by the commands:

=1. Left (or right) step, 2. MARCH, 3. Guard, 4. HALT.= (102)

the commanding officer, be posted in detachments, and sergeants, as

Corporal of the Guard

=1666.= A corporal of the guard receives and obeys orders from none
but noncommissioned officers of the guard senior to himself, the
officers of the guard, the officer of the day, and the commanding
officer. (104)

=1667.= It is the duty of the corporal of the guard to post and
relieve sentinels, and to instruct the members of his relief in their
orders and duties. (105)

=1668.= Immediately after the division of the guard into reliefs the
corporals will assign the members of their respective reliefs to posts
by number, and a soldier so assigned to his post will not be changed
to another during the same tour of guard duty, unless by direction of
the commander of the guard or higher authority. Usually, experienced
soldiers are placed over the arms of the guard, and at remote and
responsible posts. (106)

=1669.= Each corporal will then make a list of the members of his
relief including himself. This list will contain the number of the
relief, the name, the company, and the regiment of every member
thereof, and the post to which each is assigned. The list will be made
in duplicate, one copy to be given to the sergeant of the guard as
soon as completed, the other to be retained by the corporal. (107)

=1670.= When directed by the commander of the guard, the corporal of
the first relief forms his relief, and then commands: =CALL OFF.=

Commencing on the right, the men call off alternately =rear= and
=front= rank, "=one=," "=two=," "=three=," "=four=," and so on; if in
single rank, they call off from right to left. The corporal then
commands:

=1. Right, 2. FACE, 3. Forward, 4. MARCH.=

The corporal marches on the left, and near the rear file, in order to
observe the march. The corporal of the old guard marches on the right
