In the cargo hold of a C-17 aircraft, soldiers treated at the Air Force Theater Hospital at Balad Air Base, north of Baghdad, await evacuation to a military hospital in Landstuhl, Germany. This photograph was taken on Nov. 13, 2004, during a mortar attack on the base. The red lights indicate ''contingency situations.''
