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.
765. 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." (Infantry Drill Regulations, 1911.)
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.
In speaking to an officer, always stand at attention and use the word "Sir." Examples:
"Sir, Private Brown, Company B, reports as orderly."
"Sir, the first sergeant directed me to report to the captain."
