The Army Cadet Force (ACF) is one of the UK's largest and most successful youth organizations, consisting of 47,000 cadets aged 12-18 in 1,700 local detachments. The ACF provides challenging opportunities for personal and physical development through activities like drill, fieldcraft, shooting, expeditions, and sports. These activities help cadets gain skills in areas like leadership, self-confidence, and discipline while working towards qualifications like the Duke of Edinburgh Award. Membership in the ACF is free, though there may be costs for uniforms and optional activities like annual camp.
