U.S. Air Force Col. Keith Miller, commander of the 169th Operations Group of the South Carolina Air National Guard, taxis down the flight line after receiving fuel during a “hot-pit” ground refueling exercise on the flight line at McEntire Joint National Guard Base, S.C., Feb. 6, 2016.  Ground refueling while the engine is running, allows aircraft to return to flight quickly during sortie operations and combat missions. (U.S. Air National Guard photo by Senior Airman Ashleigh S.
