Marine Corps Base Camp Lejeune is a 246-square-mile (640 km2) United States military training facility in North Carolina. The base's 14 miles (23 km) of beaches make it a major area for amphibious assault training, and its location between two deep-water ports (Wilmington and Morehead City) allows for fast deployments. The main base is supplemented by five satellite facilities: Marine Corps Air Station New River, Camp Geiger, Stone Bay, Courthouse Bay, Camp Johnson, and the latest addition to the facility, the Greater Sandy Run Training Area.
