[1559]. Man addressed in formation. A man in formation shall not salute when directly addressed, but shall come to attention if at rest or at ease.
[1560]. In public places and conveyances. In public conveyances, such as railway trains and street cars, and in public places, such as theaters, honors and personal salutes may be omitted when palpably inappropriate or apt to disturb or annoy civilians present.
For instance, as a rule, it may be said that an enlisted man riding in a street car, or in the act of purchasing goods in a store, or eating in a restaurant, would not salute unless addressed by an officer. However, in case of a soldier occupying a seat in a crowded street or railway car, if he recognized a person standing to be an officer, it would be but an act of courtesy for him to raise, salute and offer the officer his seat.
[1561]. Salutes by commanders of detachments or other commands. Commanders of detachments or other commands will salute officers of grades higher than the person commanding the unit, by first bringing the unit to attention and then saluting as prescribed,—that is, with arms in hand, the salute prescribed for that arm; without arms in hand, the right-hand salute.
[1562]. Officer passing in rear of troops. When an officer entitled to the salute passes in rear of a body of troops, the troops are brought to attention when he is opposite the post of the commander.
[1563]. Bringing command to present arms or sabers before commander salutes. If the command is in line at a halt (not in the field) and armed with the rifle, or with sabers drawn, it shall be brought to present arms or present sabers before its commander salutes in the following cases: When the National Anthem is played, or when to the color or to the standard is sounded during ceremonies, or when a person is saluted who is its immediate or higher commander or a general officer, or when the national or regimental color is saluted.
[1564]. No compliments paid at drill, on march, etc. Salutes and honors, as a rule, are not paid by troops actually engaged in drill, on the march, or in the field under campaign or simulated campaign conditions. Troops on the service of security pay no compliments whatever.
[1565]. No saluting at double time, trot or gallop. Salutes are not rendered when marching in double time or at the trot or gallop. The soldier must first come to quick time or walk before saluting.
The question of gait applies to the person saluting and not to the one saluted,—so, a soldier would salute an officer passing in double time or at a trot or gallop.
