We've designed and produced a coin for the REA BD Branch, these are available from the REA BD Branch Group over on FaceBook, or from enquiring at the UK Challenge Coins website. If any other Specialist Quals in the Sappers i.e. Diver, Para, Commando, Boat Op Spec etc. would like a similar coin produced (we can change the cap badge on the front and change the 3D Bomb for a Diver Helmet, Dagger, Wings etc. Let me know here in a PM.
