Waiting for the call
U.S. Air Force Staff Sgt. Nelson Negron, front, and Airman 1st Class Donald Carey, 23rd Civil Engineer Squadron firefighters, wait for the “ok” to enter a simulated burning building during a phase II operational readiness exercise at Moody Air Force Base, Ga., Sept. 29, 2011. The scenario tested the firefighters on how fast they entered the building, cleared rooms, extinguished the fire and rescued victims still in the building.
