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".
Wales head coach Warren Gatland has named an unchanged team for Saturday's RBS 6 Nations showdown against unbeaten title favourites Ireland in Cardiff.
Gatland predictably retains the starting line-up that defeated France 20-13 in Paris 10 days ago, a result that kept alive hopes of Wales landing a third Six Nations crown in four years.
Two injury-enforced changes on the bench, meanwhile, sees uncapped Scarlets prop Rob Evans replacing Bath loosehead Paul James, who suffered a fractured thumb during the France game, while lock Jake Ball takes over from Bradley Davies.
Victory for Wales would see them stay in the title shake-up, but Ireland are chasing a a record 11th successive Test win against all opponents.

Services are to be held today to remember the four victims killed in a car crash in Wales on Friday.
Three 17-year-olds - Rhodri Miller, Corey Price and Alesha O'Connor - and a 68-year-old woman - Margaret Challis - were killed in the collision which took place in Powys as a number of vehicles travelled in convoy.
Ysgol Bro Morgannwg school in Barry, which both boys attended, said on its website there would be services this morning to reflect on what had happened, and an opportunity for pupils to receive further help and support if they need it.
"We will also open a book of remembrance and provide a suitable place to lay flowers in memory of those lost.
"The school would also like to extend an invitation to any former pupils who wish to join us."
The school's headteacher, Dylan Jones, added that both boys were very talented in their own way, Corey in football and Rhodri in science.
He described the situation as "devastating", adding: "It's been a shock to us all, and a number of their friends also are feeling the shock."

We are used to incidents on the Beacons because of the shape of the roads but it wasn't until you got close to it that you could see how serious it was. I got out of my car and approached some of the youths walking around. They seemed a bit shocked which is understandable.
