Tankers fuel the fight
U.S. Air Force Senior Airman James Partin, 376th Expeditionary Aircraft Maintenance Squadron instrument and flight control systems technician, marshals a KC-135 Stratotanker to the taxiway before take-off from the Transit Center at Manas, Kyrgyzstan, Feb. 16, 2010. In a typical flight, a KC-135 refuels several aircraft, and in the course of a deployment they'll off-load millions of pounds of fuel to hundreds of aircraft, supporting thousands of troops on the ground.
