161028-N-OG363-006 SANTA RITA, Guam (Oct. 28, 2016) A Marine Corps tank sits adjacent to a ramp during a backload of all tanks, Amphibious Assault Vehicles and other rolling stock to the maritime prepositioning ship USNS PFC Dewayne T. Williams (T-AK-3009). The tanks and vehicles were offloaded three weeks ago in Apra Harbor, U.S. Naval Base Guam, for a rare three-week opportunity for Marines and maintenance support personnel to conduct a maintenance period in Guam where the use of NBG’s reinforced piers for amphibious and tracked vehicles was more than a proof of concept, but also an exercised capability for the port at Apra Harbor far west of a typical port of call, such as Pearl Harbor, Hawaii.
