when all rise, uncover, and remain standing at attention until
the officer leaves the room or directs otherwise. Enlisted men
at meals stop eating and remain seated at attention.

(3) An enlisted man, if seated, rises on the approach of an officer,
faces toward him, stands at attention, and salutes. Standing, he
faces an officer for the same purpose. If the parties remain
in the same place or on the same ground, such compliments need
not be repeated. Soldiers actually at work do not cease work
to salute an officer unless addressed by him.

(4) Before addressing an officer an enlisted man makes the prescribed
salute with the weapon with which he is armed, or, if unarmed, with
the right hand. He also makes the same salute after receiving a
reply.

(5) In uniform, covered or uncovered, but not in formation, officers
and enlisted men salute military persons as follows: With arms in
hand, the salute prescribed for that arm (sentinels on interior
guard duty excepted); without arms, the right-hand salute.

(6) In civilian dress, covered or uncovered, officers and enlisted
men salute military persons with the right-hand salute.

(7) Officers and enlisted men will render the prescribed salutes
in a military manner, the officer junior in rank or the enlisted
men saluting first. When several officers in company are saluted
all entitled to the salute shall return it.

(8) Except in the field under campaign or simulated campaign
