The Combined Cadet Force (CCF) is a youth organisation in the United Kingdom, sponsored by the Ministry of Defence (MOD), which operates in schools, sub divided into Royal Navy, Royal Marines, Army and Royal Air Force sections. Its aim is to "provide a disciplined organisation in a school so that pupils may develop powers of leadership by means of training to promote the qualities of responsibility, self reliance, resourcefulness, endurance and perseverance".

The Officers' Training Corps (OTC), more fully called the University Officers' Training Corps (UOTC), are military leadership training units operated by the British Army. Their focus is to develop the leadership abilities of their members whilst giving them an opportunity to take part in military life whilst at university. OTCs also organise non-military outdoor pursuits such as hill walking and mountaineering. UOTC units are not deployable units nor are their cadets classed as trained soldiers until completion of MOD 1 training. The majority of members of the UOTC do not go on to serve in the regular or reserve forces.
