ARTICLES OF WAR
The Army is governed by the Articles of War, which can be found in the Army Regulations. Any laws, orders, et cetera, pertaining to the Army must not violate directly or indirectly any of the Articles of War. It is therefore desirable that each Reserve Officer know where to find them and become, in a general way, familiar with them.
GENERAL ADVICE
To become a first-class drillmaster is desirable and necessary. But, being one, you are not to be intrusted with the command of troops in the field unless you have gone much farther than that. To become an excellent drillmaster means simply that you have mastered a detail. In order to become one you should bear this in mind: You cannot teach a man how to do a thing unless you know that thing yourself. If you don't know your drill, don't try to "bluff" your men. Burn the midnight oil, or remain a private.
