A-5. Other instances when saluting may or may not be required—when in formation, not in formation, outdoors, and indoors. Each have different requirements in regards to salutes and are discussed herein
In Formation
A-6. Individuals in formation do not salute or return salutes except at the command Present, ARMS. The individual in charge salutes and acknowledges salutes for the entire formation. Commanders of organizations or detachments that are not a part of a larger formation salute officers of higher grade by bringing the organization or detachment to attention before saluting. When in the field under battle or simulated battle conditions, the organization or detachment is not brought to attention. An individual in formation at ease or at rest comes to attention when addressed by an officer.
Not in Formation
A-7. On the approach of an officer, a group of individuals not in formation is called to Attention by the first person noticing the officer, and all come sharply to Attention and salute. This action is to be taken at approximately six paces away from the officer, or the closest point of approach. Individuals participating in games, and members of work details, do not salute. The individual in charge of a work detail, if not actively engaged, salutes and acknowledges Salutes for the entire detail. A unit resting alongside a road does not come to Attention upon the approach of an officer; however, if the officer addresses an individual (or group), the individual (or group) comes to Attention and remains at Attention (unless otherwise ordered) until the termination of the conversation, at which time the individual (or group) Salutes the officer.
Outdoors
A-8. Whenever and wherever the U.S. national anthem, “To the Color,” “Reveille,” or “Hail to the Chief” is played, at the first note, all dismounted personnel in uniform and not in formation face the flag (or the music, if the flag is not in view), stand at Attention, and render the prescribed Salute. The position of Salute is held until the last note of the music is sounded. Military personnel not in uniform will stand at Attention (remove headdress, if any, with the right hand), and place the right hand over the heart. Vehicles in motion are brought to a Halt. Persons riding in a passenger car or on a motorcycle dismount and salute. Occupants of other types of military vehicles and buses remain in the vehicle and sit at attention; the individual in charge of each vehicle dismounts and renders the Hand Salute. Tank and armored car commanders Salute from the vehicle.
Indoors
A-9. When the national anthem is played indoors, officers and enlisted personnel stand at Attention and face the music, or the flag if one is present. There is no saluting indoors except when reporting to a commander and when on duty as a guard as previously mentioned at the beginning of this appendix.
