It is in the Field Training of the Infantry that the cadet acquires a real knowledge of command. He must be able to size up situations and quickly form a decision. He must then issue orders, clear and definite, to cover the case. It is in these drills that he learns something of the art of handling troops and what is the feeling of responsibility. The cadets who actually exercise command are the First Classmen. They are detailed by roster, irrespective of whether they are privates or cadet officers, so that every man has many opportunities to command a company before he graduates. It is highly important that the cadet should be given practice in appearing before a body of men and in giving them instructions. Nothing helps so much to give him confidence in himself. It is of great value to him when he joins his regiment in the Service. Cadets of the First Class are therefore detailed for every kind of duty. They are company commanders, acting adjutants, lieutenants, officers of the day and of the guard. Whenever there is a chance to place responsibility upon the cadet, advantage is taken of it by the Commandant. The Infantry instruction is progressive. The First Classmen are trained in more advanced work by means of tactical walks. These exercises are similar to those prescribed for officers in the Service and are in line with their future work as subalterns. An officer takes four or five men with him to some neighboring terrain well adapted to a particular problem. All of the different phases of the problem are considered and the cadets required to size up each situation and issue their orders as if in actual warfare. They are provided with maps which they must be able to read with facility. At the close of the exercise the officer holds a critique.
