Here is the Army Dress Committees final list (dated May 2004) http://www.army.mod.uk/presscentre/rank_and_regimental_insignia/Tactical_Recognition_Flashes.htm How many are actually being worn? From what I have been told, The existence of a TRF Design approved and âregisteredâ by/with the Army Dress Committee does not indicate that the given Regiment or Corps will in fact ever wear it! But units assigned to 16 Air Assault Brigade will wear that TRF as its DZ Flash. Units that had more than 1 DZ Flash (other than the Parachute Regiment) will in future only wear the Regimental TRF (What about the Royal Engineer EOD Flash should no longer be worn, and the RLC Black/Red should be changed to Blue/Yellow) If this is followed to the letter, I will be very surprised !!!
