Tactical recognition flash (TRF) is the British military term for a coloured patch worn on the right arm of combat clothing by members of the British Army,[1]Royal Navy and Royal Air Force. A TRF serves to quickly identify the regiment or corps of the wearer, in the absence of a cap badge. It is similar to, but distinct from, the DZ Flashes worn by members of Airborne Forces.
Red and blue tactical recognition flash of the Royal Artillery.
TRFs should not be confused with formation signs or insignia, which are used to denote the formation (usually brigade or division or a higher headquarters) and are worn in addition to TRFs by a member of any regiment or corps serving in that formation.
Tactical Recognition Flashes are not to be worn by Cadet Force Adult Volunteers (CFAVs) or cadets of the Army Cadet Force and army section of the Combined Cadet Force irrespective of any affiliation to a Corps or Regiment.[2] Cadets and CFAVs do wear county and contingent flashes of the Army Cadet Force and Combined Cadet Force respectively.[2] Officers of the Air Training Corps and the RAF Section of the Combined Cadet Force wear the RAF tactical recognition flash, Adult Warrant Officers and Senior Non-Commissioned Officers wear the RAFAC Staff formation flash, and cadets wear RAFAC Cadet formation flash.[3]
