A U.S. Army Modular Causeway System transports containers of Army equipment from the USNS Pollux to a pier in the harbor of Pusan, Republic of Korea, on Oct. 19, 1998, for Exercise Foal Eagle '98. Foal Eagle '98 is a combined, joint exercise supported by forces from the U.S. and Republic of Korea. In addition to providing hands-on field experience for forces of both nations, Foal Eagle '98 was designed to test rear area protection operations and major command, control and communications systems. Pollux is one of eight Fast Sealift Ships belonging to the Military Sealift Command that have special features allowing them to load and off-load cargo in places lacking normal port facilities. Causeway systems are deployable aboard container ships and other cargo vessels as the Pollux.
