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.

The Royal Yeomanry (RY) is the senior reserve cavalry regiment of the British Army. Equipped with Supacat Jackal variants, their role is to conduct mounted and dismounted formation reconnaissance. The Regimental Headquarters is located in Leicester, with squadrons in Fulham, Nottingham, Dudley, Croydon, Telford, and Leicester. The regiment is part of the Royal Armoured Corps and is only reserve cavalry regiment to resubordinate into regular brigade as part of the Future Soldier Programme, which in turn arose from the Integrated Review of Security, Defence, Development and Foreign Policy published in March 2021.
