Maj. (Dr.) Steve Barnes (left) works with vascular surgeon Maj. (Dr.) Cabot Murdock to remove shrapnel from a U.S. Soldier at the Air Force Theater Hospital at Balad Air Base, Iraq, Aug. 7. Severely wounded by a roadside bomb, the Soldier's life hung in the balance until the surgeons found and extracted fragments of metal and bone from the Soldier's iliac veins deep in his pelvis.
