ady
at attention. The senior commander of the two guards will then
command: "1. Old and new guards, 2. Present, 3. Arms."

The junior will salute at the command "Present Arms" given by
the senior. After the salute has been acknowledged, the senior
brings both guards to the order.

364. After the salutes have been acknowledged by the officers of
the day, each guard is brought to an order by its commander; the
commander of the new guard then directs the orderly or orderlies
to fall out and report and causes bayonets to be fixed if so
ordered by the commanding officer; bayonets will not then be
unfixed during the tour except in route marches while the guard
is actually marching or when specially directed by the commanding
officer.

The commander of the new guard then falls out members of the
guard for detached posts, placing them under charge of the proper
noncommissioned officers, divides the guard into three reliefs,
first, second, and third, from right to left, and directs a list
of the guard to be made by reliefs. When the guard consists of
troops of different arms combined, the men are assigned to reliefs
so as to insure a fair division of duty under rules prescribed
by the commanding officer.

365. The sentinels and detachments of the old guard are at once
relieved by members of the new guard, the two guards standing at
ease or at rest while these changes are being made. The commander
of the old transmits to the commander of the new guard all his
orders, instructions, and information concerning the guard and
its duties. The commander of the new guard then takes possession
of the guardhouse and verifies the articles in charge of the
guard.

366. If considerable time is required to bring in that portion
of the old guard still on post, the commanding officer may direct
that as soon as the orders and property are turned over to the
new guard the portion of the old guard at the guardhouse may be
marched off and dismissed. In such a case the remaining detachment
or detachments of the old guard will be inspected by the commander
of the new guard when they reach the guardhouse. He will direct the
senior noncommissioned officer present to march these detachments
off and dismiss them in the prescribed manner.

367. In bad weather, at night, after long marches, or when the
guard is very small, the field music may be dispensed with.
