=921.= 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 saber= 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. =922.= At parades and other ceremonies, under arms, the command shall render the prescribed salute and shall remain in the position of salute while the National Anthem is being played; also at retreat and during ceremonies when to the color is played, if no band is present. If not under arms, the organizations shall be brought to attention at the first note of the National Anthem, =to the color= or =to the standard=, and the salute rendered by the officer or noncommissioned officer in command as prescribed in regulations, as amended herein. =910.= Whenever the National Anthem is played at any place when persons belonging to the military service are present, all officers and enlisted men not in formation shall stand at attention facing toward the music (except at retreat, when they shall face toward the flag). If in uniform, covered, they shall salute at the first note of the anthem, retaining the position of salute until the last note of the anthem. If not in uniform and covered, they shall uncover at the first note of the anthem, holding the headdress opposite the left shoulder and so remain until its close, except that in inclement weather the headdress may be slightly raised. The same rules apply when =to the color= or =to the standard= is sounded as when the National Anthem is played. When played by an Army band, the National Anthem shall be played through without repetition of any part not required to be repeated to make it complete. The same marks of respect prescribed for observance during the playing of the National Anthem of the United States shall be shown toward the national anthem of any other country when played upon official occasions. =917.= Officers and enlisted men passing the uncased color will render honors as follows: If in uniform, they will salute as required by subparagraph (5), paragraph 759; if in civilian dress and covered, they will uncover, holding the headdress opposite the left shoulder with the right hand; if uncovered, they will salute with the right-hand salute. The national flag belonging to dismounted organizations is called a color; to mounted organizations, a standard. An uncased color is one that is not in its waterproof cover. Privates do not salute noncommissioned officers. =Prisoners are not permitted to salute;= they merely come to attention if not actually at work. The playing of the National Anthem as a part of a medley is prohibited in the military service. =Section 8. Courtesies in conversation.=
