Cadets (youth program)

Cadets or cadet corps are voluntary youth programs sponsored by a national military service or ministry of defence. These programs are aimed to provide youths with activities associated with military or paramilitary training, including drills, physical fitness, and education. Although these youth organisations are modelled after their sponsoring military service, they do not form a part of these services nor do they constitute a military service in their own right.

Several civilian organisations, including civil defence, police services, and emergency medical services like St John Ambulance, may also operate or sponsor their own "cadet" youth programs.
