Was wondering about the difference between US and British approaches picking up casualties by helicopter. Please say if any of the info I've picked up is wrong/other proceedures are also used. British have MERT (medical emergency response team) which comes in one chinook, with gunners on the side and at the back, with a trained nurses (and sometimes a doctor?) onboard, with RAF regiment (or other soldiers) onboard to provide protection once the helicopter lands. e.g. YouTube - British MERT in Afghanistan June 2009 However, the Americans use 2 helicopters (often smaller Blackhawks compared to large British chinooks): one with a red cross on it to land and pick up casualties, which has no armaments, and a "chase" helicopter which circles overhead as the casualty is picked up and has lots of guns to shoot Terry with. e.g. YouTube - Blood and Dust. Pros and cons of each approach? My thoughts: Chinook is a bigger target, but has more room to treat people in (and often there is a qualified doctor onboard, not just a medic so more advanced procedures can be undertaken?) US helicopters are a smaller target, chase helicopter provides better fire support, but seems a bit of a "f*** you" as they side-step the rules about medical (red cross marked) vehicles not carrying armaments.
