The Combined Cadet Force (CCF) is a unique educational partnership that operates in schools across the UK. Through enjoyable military themed and adventurous activities, cadets have the opportunity to take responsibility, develop skills such as leadership, self-reliance, resourcefulness, endurance and perseverance. CCF contingents contain one or more sections from the British Army, the Royal Navy, Royal Marines or the Royal Air Force, and promote the aims and values of the Services they represent. The CCF is not part of the Armed Forces. While adult volunteers and cadets do wear uniform, they do not incur any liability for service or compulsory training in the armed forces as a result of being a CCF member. Each school contingent is run by a team of enthusiastic adult volunteers drawn, in the main, from teachers within the school, although outside volunteers are often invited to help. Adult volunteers have the opportunity to gain nationally-recognised qualifications in leadership, management and outdoor pursuits.

Training opportunities for cadets occur during weekly parades in school, whole day and weekend training periods (field days), at annual military camps, on courses run by the armed forces specifically for cadets and through adventurous training expeditions arranged on an ad hoc basis.
