For personnel in the Armed Forces, like Sergeant Stuart Pearson, who get injured or fall ill, the operational medical care pathway, as it is known in MOD, can span continents and oceans, ensuring the best treatment in theatre and at home.
The journey back to recovery for all Armed Forces personnel has up to seven main stages. See Related Links >>> for photographs which show and explain every stage of the path.
Sergeant Stuart Pearson from 3 Para Battalion of 16 Air Assault Brigade here tells us his story from the moment he lost his leg in the mine blast to his return to duty, and reflects on the medical care he received:
"I lost my left leg in Helmand on 6 September 2006. Moments earlier, my friend Corporal Stuart Hill had stood on a mine and been badly injured. While I was looking for a helicopter landing site so we could evacuate him, I stood on a second mine. I also suffered massive blast injuries to my right leg, which was saved, thanks to the skills of the medics.
"I remember thinking: "Oh shit, not me!" I couldn't believe it. I injected myself with morphine straight away and my mate Andy Barlow applied a tourniquet to my stump.
"In the chaos that followed, there were two further explosions and, again, I was caught by the blast. Eventually a US Black Hawk helicopter winched us out of the minefield and took us to meet a Chinook that had medics aboard.
"On our journey to the field hospital at Camp Bastion, Corporal Mark Wright, who had also been injured in the minefield, died.
"I spent two days in the field hospital undergoing further amputation to stop gangrene, and doctors opened up my stomach, fearing internal injuries. Luckily, none were found.
"From there, I was flown on an Aeromed C17 to Birmingham Airport. An ambulance then whisked me straight to Selly Oak Hospital in Birmingham. Staff cleaned my wounds and applied skin grafts to my right leg, using skin from my right thigh. My right ankle was smashed but by the end of October doctors had managed to save my foot.
