The Sixty-Seventh Combat Support Hospital, located 250 miles northwest of Baghdad, was not like most hospitals. For starters, the doctors carried guns. As officers in the U.S. Army, the physicians were required to wear sidearms, which were deposited in a lockbox before every shift. The hospital often treated Iraqi insurgents, who were known to spit in attending physicians' faces as they received treatment. If they (or a disoriented U.S. soldier) got their hands on a weapon, a firefight could break out in the operating room.
