Medics who are part of a new "military style" rapid response team in Wales will be able to take blood to casualties in what is a world first.
The multi-agency Emergency Medical Retrieval and Transfer Service (EMRTS) Cymru will launch next month and bring some of medical skills usually used on the battlefield to civilian life.
The EMRTS will bring together a new flying doctors service, A&E specialists from the NHS and critical care experts such as advanced nurses and paramedics.
Officials say the team will be able to deal with a wide raft of life-or-death situations including mass casualty events.
Wales' Deputy Minister for Health, Vaughan Gething, said it "will be one of, if not the most, comprehensively equipped pre-hospital teams in the world".
