[1535]. Army officers. All Army officers are saluted by their juniors and by enlisted men.
[1536]. Navy, Marine Corps, Volunteer and National Guard officers. Soldiers at all times and in all situations salute officers of the Navy, Marine Corps, and National Guard the same as they salute officers of the Regular Army.
[1537]. Reserve Corps officers. Although the subject is not at present (March, 1917) covered by orders or regulations, it goes without saying that soldiers would salute members of the Officers' Reserve Corps on active duty the same as they salute their own officers.
[1538]. Foreign naval and military officers. The Manual of Interior Guard Duty requires sentinels to salute foreign naval and military officers, but there are no instructions about other enlisted men saluting them. However, as an act of international courtesy, they should be saluted the same as our own officers.

Day or night, covered or uncovered, whether either or both are in uniform or civilian clothes, salutes shall be exchanged between officers and enlisted men not in a military formation, nor at drill, work, games or mess, on every occasion of their meeting, passing near or being addressed, the junior in rank or the enlisted man saluting first.
[1540]. Saluting when making and receiving reports. When making or receiving official reports, or on meeting out of doors, all officers will salute.
Military courtesy requires the junior to salute first, but when the salute is introductory to a report made at a military ceremony or formation, to the representative of a common superior (as, for example, to the adjutant, officer of the day, etc.), the officer making the report, whatever his rank, will salute first; the officer to whom the report is made will acknowledge by saluting that he has received and understood the report.
[1541]. Saluting distance. Saluting distance is that within which recognition is easy. In general, it does not exceed 30 paces.
As to the distance at which the salute should be made, the following is what has been the practice in the Army:
