# Tactical recognition flash

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, 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.
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.
