A special Channel 4 News report from the combat medical hospitals in Iraq, shows the physical and psychological cost of the war.
At Baghdad's Combat Support Hospital, the Black Hawks are coming in thick and fast, ferrying America's war-wounded straight off the battlefield; more than 27,000 of them in four-and-a-bit years.

"That's the most horrific thing I've seen in my ten years in medicine. Can you ever be 100 per cent prepared for what you see? No." - Paul Corcoran, Chief Surgeon
The US takes almost half its casualties in Anbar Province,northwest of Baghdad. Orderlies and gurneys are on permanent standby at the Al-Asad Combat Hospital.
