A line of U.S. Army AH-64 Apache attack helicopters sit ready to be loaded on a U.S. Air Force C-5B Galaxy at Bagram Air Field, Afghanistan, Aug. 30, 2012. The C-5 can carry up to six Apache helicopters in a single load depending on configuration. The C-5s payload capacity made it the ideal choice for the relief in place/transfer of authority process of the departing 82nd Combat Aviation Brigade and arriving 101st Combat Aviation Brigade.
