Air Force Staff Sgt. Derek Allen (right) and his brother, Army Cpl. Greg Allen, stand together for the first time since 2009, Dec. 23, 2012, on Bagram Airfield, Afghanistan. The brothers' leaders worked to reunite them for the holidays after an A-10 Thunderbolt II aircraft maintained by Derek provided vital air support to Soldiers of the 101st Airborne Division, including his brother. Derek is assigned to the 455th Expeditionary Aircraft Maintenance Squadron. (U.S. Air Force photo/Master Sgt. Jun Kim)
