“ Between these two things—discipline in itself and a personal faith in the military value of discipline—lies all the difference between military maturity and mediocrity. A salute from an unwilling man is as meaningless as the moving of a leaf on a tree; it is a sign only that the subject has been caught by a gust of wind. But a salute from the man who takes pride in the gesture because he feels privileged to wear the uniform of the United States, having found the service good, is the epitome of military virtue. ”
