Adult leadership is provided by members of the Canadian Forces Reserve sub-component which is known as the Cadet Organization Administration and Training Service, which is composed mostly of officers of the Cadet Instructor Cadre (CIC) branch. The leadership of each individual corps is supplemented, if necessary, by contracted Civilian Instructors (CIs), authorized adult volunteers, and, on occasion, officers and non-commissioned members of other Canadian Armed Forces branches. The CIC branch is specifically trained to administer and support the Royal Canadian Sea, Army, and Air Cadet training program. Like all other Reserve Force members, they come from all walks of life and all parts of local communities. Some commissioned CIC officers are former cadets themselves, while others many have former Regular Force or Reserve Force service.
