Members of the 56th Medical Group at Luke Air Force Base, Ariz., erect a mobile medical hospital during a regional training exercise April 3, 2006, at Papago Military Reservation in Phoenix. About 500 military members, including members of the 944th Fighter Wing, from across the United States are currently undergoing medical training including triage, medical command and control, medical air evacuation, patient management and transportation, and wound care as part of the "Coyote Crisis Campaign." This training allows military members to work closely with community medical assets to prepare for events like natural disasters or terrorist attacks. (U.S. Air Force photo/Master Sgt.
