The Invisible Enemy in Iraq

A homemade bomb exploded under a Humvee in Anbar province, Iraq, on August 21, 2004. The blast flipped the vehicle into the air, killing two US marines and wounding another - a soft-spoken 20-year-old named Jonathan Gadsden who was near the end of his second tour of duty. In previous wars, he would have died within hours. His skull and ribs were fractured, his neck was broken, his back was badly burned, and his stomach had been perforated by shrapnel and debris.

Gadsden got out of the war zone alive because of the Department of Defense's network of frontline trauma care and rapid air transport known as the evacuation chain. Minutes after the attack, a helicopter touched down in the desert. Combat medics stanched the marine's bleeding, inflated his collapsed lung, and eased his pain. He was airlifted to the 31st Combat Support Hospital in Baghdad, located in an old health care facility called the Ibn Sina, which had formerly catered to the Baathist elite. Army surgeons there repaired Gadsden's cranium, removed his injured spleen, and pumped him full of broad-spectrum antibiotics to ward off infection.
