Via Winds of Change, a story from Newsweek/MSNBC: On Call in Hell.

Navy doctor Lt. Commander Richard Jadick volunteers to go to Iraq:

The night before the assault, Jadick hopped into a command Humvee taking a reconnaissance mission from the headquarters base outside the city. He wanted to see what he was up against. In treating traumatic injuries, there is something known as the golden hour. A badly injured person who gets to the hospital within an hour is much more likely to be saved. But Jadick knew that in combat the "golden hour" doesn't exist. Left unaided, said Jadick, the wounded "could die in 15 minutes, and there are some things that could kill them in six minutes. If they had an arterial bleed, it could be three minutes."
