June 6, 1917.

Memorandum:

1. Hereafter, in all lecture halls, section rooms, and other meetings, members of the Reserve Officers' Training Corps will arise upon the entrance of the instructor and will stand at "attention" until he directs them to be seated, or until he has taken his seat.

Cadets will be in their seats promptly for all lectures and class-room work, and will not leave until dismissed unless excused by the instructor.

2. At all formations in ranks, except when actually receiving instruction, cadets will be brought to "attention" by the officer or non-commissioned officer in charge upon the approach of a tactical instructor. The officer or non-command "rest" or "at ease" after the instructor has passed, or if he remains in the vicinity after acknowledging the salute. No courtesies will be rendered, however, on any field work (sketching, target practice, marches in the field, etc.) unless cadets are addressed by, or addressing, an officer.

The tactical instructors referred to herein are the commissioned officers of the U. S. Army, the Officers of the French Military Mission, the regimental staff, the battalion commanders and their adjutants, and others designated as tactical instructors (these are distinguished by gilt insignia of rank).

3. On all other occasions, cadets will come to "attention" upon the approach of an officer (including cadet captains and lieutenants). If grouped together and not in ranks, the first to perceive the officer will give the word "attention," when all will remain in this position until the officer has passed, or directs otherwise. If not in ranks, all will render the prescribed salute. Individual cadets in like manner observe these rules.

4. Attention is called to the following changes in Army Regulations, which also govern the Corps:

"383. Substitute the following: 1, 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 officer junior in rank or the enlisted man saluting first.

"2. When an officer enters a room where there are several enlisted men, the word "attention" is given by some one who perceives him, when all rise, uncover, and remain standing at attention until the officer leaves the room or directs otherwise. Enlisted men at meals stop eating and remain seated at attention.

"3. An enlisted man, if seated, rises on the approach of an officer, faces toward him, stands at attention, and salutes. Standing, he faces an officer for the same purpose. If the parties remain in the same place or on the same ground such compliments need not be repeated. Soldiers actually at work do not cease work to salute an officer unless addressed by him.

"4. Before addressing an officer, an enlisted man makes the prescribed salute with the weapon with which he is armed, or, if unarmed, with the right hand. He also makes, the same salute after receiving a reply. (C.A.R., No. 50, Jan. 8, 1917). (2143705 D--A.G.O.)

"383. Substitute the following: 1. In uniform covered or uncovered, but not in formation, officers and enlisted men salute military persons as follows: With arms in hand, the salute prescribed for that arm (sentinels on interior guard duty excepted); without arms, the righthand salute.

"2. In civilian dress covered or uncovered, officers and enlisted men salute military persons with the right-hand salute.

"3. Officers and enlisted men will render the prescribed salutes in a military manner, the Officer, junior in rank or the enlisted man saluting first. When several officers in company are saluted, all entitled to the salute shall return it.

"4. Except in the field under campaign or simulated campaign conditions, a mounted officer (or soldier) dismounts before addressing a superior officer not mounted.
