The Royal Air Force Volunteer Reserve (Training Branch), often abbreviated to RAFVR(T) is a voluntary element of the British Royal Air Force specifically appointed in a training role within the RAFVR. Members of the RAFVR(T) have no call-up liability and often operate part time on Air Experience Flights, Volunteer Gliding Squadrons, or more commonly in the local structure of the Air Cadet Organisation - either the RAF Sections of the Combined Cadet Force (CCF), or the Air Training Corps (ATC).
