Marines with Bulk Fuel Company, 1st Marine Logistics Group, team up with sailors from Amphibious Construction Battalion 1 to perform a beach unloading exercise using the Beach Termination Unit, in Coronado, California, Aug. 1-4, 2015. Approximately 30 Marines with Bulk Fuel Company, 7th Engineer Support Battalion, 1st Marine Logistics Group, teamed up with sailors from Amphibious Construction Battalion 1 to conduct a beach unloading exercise. What made the training unique was the use of the BTU, which allows Marines to transfer fuel from a ship out in the ocean to Marines on land. - Marines with Bulk Fuel Company, 1st Marine Logistics Group, team up with sailors from Amphibious Construction Battalion 1 to perform a beach unloading exercise using the Beach Termination Unit, in Coronado, California, Aug. 1-4, 2015.
