Marker buoys along a sunken pipeline stretch from Dogu Beach to merchant vessel Wheeler, stationed several miles off the coast, to simulate pumping fuel from an off-shore vessel to improvised an fuelling station during a Combined Joint Logistics Over-the-Shore Exercise (CJLOTS) April 17, 2013. CJLOTS provides a valuable opportunity for U.S. military personnel and Korean allies to gain working experience and to identify any existing gaps in ability to deploy these units and operate as part of a joint and combined military task force on the Korean peninsula.
