An AV-8B Harrier, piloted by Capt. Daniel S. Fiust of Marine Attack Squadron 513, takes in fuel March 28 while training above Fort Hunter Liggett, seen below. A KC-130J Hercules turboprop aircraft from San Diego-based Marine Aerial Refueler Transport Squadron 352 circled dozens of times, 22,000 feet above the remote Army post, and refueled the Harrier three times, pumping 15,000 pounds of fuel in total. Fiust conducted surveillance, reconnaissance and simulated guided-munitions strikes as part of an 11th Marine Expeditionary Unit air-ground task force exercise. The Harrier flew from the squadron’s home station in Yuma, Ariz., stopping once at Naval Air Station North Island in San Diego. Six of the squadron’s jets will reinforce the 11th Marine Expeditionary Unit’s aviation combat element, Marine Medium Helicopter Squadron 166 (Reinforced) when they deploy. - An AV-8B Harrier, piloted by Capt.
