Ranger Challenge is called the "varsity sport" of the Army ROTC. Focusing on the basic infantry skills, squad-sized teams compete against other schools in the region on their abilities in constructing a rope-bridge, the Army Physical Fitness Test, land navigation, a 10 kilometer road march, and two or three other events chosen each year. The competition takes place in the fall, and all cadets in good academic standing are invited to take part. Ranger Challenge cadets conduct Physical Training (PT) five times a week and many weekends, separate from the rest of the battalion, in order to obtain training for the competition. The competition is usually the second week in October and cadets begin their training as a team as soon as school starts. (Many start individually training much earlier).
