Prospective weapons and tactics instructors ran a fuel line from the fuselage tank and out the paratroop door of this KC-130J Super Hercules during an exercise at Stoval Airfield, Arizona, on 15 October 2010. The line runs from the aircraft and is used to refuel ground vehicles. Instructors, pilots, and aircrew were conducting this training as part of Weapons and Tactics Instructor Course 1-11, which is hosted by Marine Aviation and Weapons Tactics Squadron One based at MCAS Yuma, Arizona.
