Bunker down
U.S. Air Force Senior Airman Erica Mitchell, 23rd Wing chaplain assistant, right, and Chaplain (Capt.) Tony King, also with the 23rd Wing, sit in a simulated bunker while in alarm condition during a phase II operational readiness exercise at Moody Air Force Base, Ga., Sept. 28, 2011. Depending on the alarm status, personnel outside reported to bunkers to ensure their safety and kept in contact with their unit control center to ensure 100 percent accountability.
