Since the formation of the Unit, R&S Wing aircrew have operated on virtually all in-service RAF, CHF and AAC helicopter types; the aircraft depicted on this print highlight those types in which Wing aircrew operated as at January 2018. The R&S Wg HQ is located at RAF Benson in the CAE Medium Support Helicopter Aircrew Training Facility.
