Cadets follow very unique customs and traditions that are premised on the principle that "no one is fit to command who has not learned to obey." This tradition calls for certain standards which the plebe - fresh from civilian life must meet. It also considers several corrective measures the upperclassmen may take to enable the plebes to meet the standards. In other words, the custom operates to develop good qualities and individuals.
