Every man knows how to walk and run, but few of them how to do so without making extra work of it. One of the first principles in training the body of the soldier is to make each set of muscles do its own work and save the strength of the other muscles for their work. Thus the soldier marches in quick time,—walks,—with his legs, keeping the rest of his body as free from motion as possible. He marches in double time,—runs,—with an easy swinging stride which requires no effort on the part of the muscles of the body.

The marchings also teach the soldier to walk and run at a steady gait. For example, in marching in quick time, he takes 120 steps each minute; in double time, he takes 180 per minute.

Furthermore, the marchings teach the soldier to walk and run with others,—that is, in a body.

[6]. Saluting. The form of salutation and greeting for the civilian consists in raising the hat.

The form of salutation and greeting for the military man consists in rendering the military salute,—a form of salutation which marks you as a member of the Fraternity of Men-at-arms, men banded together for national defense, bound to each other by love of country and pledged to the loyal support of its symbol, the Flag. For the full significance of the military salute see [paragraph 1534].

[7]. Manual of Arms. The rifle is the soldier's fighting weapon and he must become so accustomed to the feel of it that he handles it without a thought,—just as he handles his arms or legs without a thought,—and this is what the manual of arms accomplishes.

The different movements and positions of the rifle are the ones that experience has taught are the best and the easiest to accomplish the object in view.

[8]. School of the Squad. The object of squad drill is to teach the soldier his first lesson in team-work,—and team-work is the thing that wins battles.

In the squad the soldier is associated with seven other men with whom he drills, eats, sleeps, marches, and fights.

The squad is the unit upon which all of the work of the company depends. Unless the men of each squad work together as a single man,—unless there is team-work,—the work of the company is almost impossible.
