. R. 405.)

342. On the death of an officer at a military post the flag is
displayed at halfstaff and so remains between reveille and retreat
until the last salvo or volley is fired over the grave; or if
the remains are not interred at the post until they are removed
therefrom. (A. R. 422.)

343. During the funeral of all enlisted man at a military post
the flag is displayed at halfstaff. It is hoisted to the top
after the final volley or gun is fired or after the remains are
taken from the post. The same honors are paid on the occasion
of the funeral of a retired enlisted man. (A. R. 423.)

344. When practicable, a detail consisting of a noncommissioned
officer and two privates of the guard will raise or lower the
flag. This detail wears side arms or if the special equipments
do not include side arms then belts only.

The noncommissioned officer, carrying the flag, forms the detail
in line, takes his post in the center and marches it to the staff.
The flag is then securely attached to the halyards and rapidly
hoisted. The halyards are then securely fastened to the cleat
on the staff and the detail marched to the guardhouse.

345. When the flag is to be lowered, the halyards are loosened
from the staff and made perfectly free. At retreat the flag is
lowered at the last note of retreat. It is then neatly folded
and the halyards made fast. The detail is then re-formed and
marched to the guardhouse, where the flag is turned over to the
commander of the guard.

The flag should never be allowed to touch the ground and should
always be hoisted or lowered from the leeward side of the staff,
the halyards being held by two persons.

SECTION 18. REVEILLE AND RETREAT GUN.

346. The morning and evening gun will be fired by a detachment
of the guard, consisting, when practicable, of a corporal and two
privates. The morning gun is fired at the first note of reveille,
or, if marches be played before the reveille, it is fired at the
beginning of the first march. The retreat gun is fired at the
last note of retreat.

The corporal marches the detachment to and from the piece, which
is fired, sponged out, find secured under his direction.

SECTION 19. GUARD MOUNTING.

347. Guard mounting will be formal or informal as the commanding
officer may direct. It will be held as prescribed in the drill
