The U.S. Army Marksmanship Unit (AMU) sent their Action Shooting Team to train the British Army Combat Action Shooting Team. Here is a video of the BACST showing off what they learned in a 3Gun style action stage. They are using the SA80 and what looks like a Glock 17. The British soldier is in Multi-Terrain Pattern (MTP) which is a hybrid of the British Disruptive Pattern Material (DPM) and Multicam.
