MILITARY DISCIPLINE AND COURTESY. SECTION 1. OATH OF ENLISTMENT. Every soldier on enlisting in the Army takes upon himself the following obligation: "I,--------, do solemnly swear (or affirm) that I will bear true faith and allegiance to the United States of America; that I will serve them honestly and faithfully against all their enemies whomsoever; and that I will obey the orders of the President of the United States, and the orders of the officers appointed over me according to the Rules and Articles of War." (109th Article of War.) SECTION 2. OBEDIENCE. The very first paragraph in the Army Regulations reads: "All persons in the military service are required to obey strictly and to EXECUTE PROMPTLY the lawful orders of their superiors." Obedience is the first and last duty of a soldier. It is the foundation upon which all military efficiency is built. Without it an army becomes a mob, while with it a mob ceases to be a mob and becomes possessed of much of the power of an organized force. It is a quality that is demanded of every person in the Army, from the highest to the lowest. Each enlisted man binds himself, by his enlistment oath, to obedience. Each officer, in accepting his commission, must take upon himself the same solemn obligation.
