The Special Forces Support Group (SFSG) is a special forces support unit of the British Armed Forces. The SFSG was formed officially on 3 April 2006 to provide support to the Special Air Service, the Special Boat Service and the Special Reconnaissance Regiment on operations. It is a tri-service unit, composed of the 1st Battalion, Parachute Regiment (1 Para), a company of Royal Marine Commandos (F Coy), and a flight (platoon) from the Royal Air Force Regiment.
The SFSG also acts as the hunter force during the SERE phase of the UKSF Selection; in addition, the SFSG also has a rotating company group trained in Counter Terrorism (CT) to support the on-call SAS or SBS squadrons on CT rotation.
