[1550]. Addressing or being addressed by an officer. Before addressing an officer, or when addressed by 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.
[1551]. How salutes are rendered in uniform. 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.
[1552]. Rifle salute. Enlisted men out of doors and armed with the rifle, salute with the piece at the right shoulder; if indoors, the rifle salute is rendered at the order or trail.
[1553]. Saber salute. An enlisted man armed with the saber renders the saber salute, if the saber is drawn; otherwise he salutes with the hand.
[1554]. Sentinels on post. A soldier salutes with the "present arms" only when actually on post as a sentinel doing interior guard duty. At all other times when armed with the rifle he salutes with the prescribed rifle salute.
The general rules and principles of saluting apply to sentinels on post doing interior guard duty, except, as just stated, they salute by presenting arms when armed with the rifle. However, they do not salute if it interferes with the proper performance of their duties.
[1555]. How salutes are rendered in civilian dress. In civilian dress, covered or uncovered, officers and enlisted men salute military persons with the right-hand salute.
