Combat air refueling over Afghanistan
A KC-10 Extender from the 908th Expeditionary Air Refueling Squadron refuels an aircraft Feb. 1, 2010, over Afghanistan, during Operation Enduring Freedom air refueling operations. The air refueling capability of the KC-10 in combat operations allows fighters to provide close-air support for "troops in contact" in Afghanistan and other areas of operations.
