The camp was constructed during the mid 1930s by the
Imperial Japanese Army. In 1945, Japan surrendered to the U.S. Army, and the U.S. Army permanently designated the post as a DSAFE depot. Other operations include usage as an
ASCOM (Army Support Command) complex.
AMC and
CECOM started relying on their contractors for communication and defense equipment. Their solution was to make united civilian-powered contactor complexes called the ESSC. These complexes were located at Fort Bragg, North Carolina, Fort Hood, Texas; Friedrichsfeld, Germany and Camp Market. The complexes could support six Intelligence Electronic Warfare Regional Support Centers. The ASCOM area's acronym comes from the names of Camp Grant, Camp Market, Camp Tyler and Camp Hayes. The USMC Support Command for South Korea and the Inchon Replacement Center were the first major tenants at ASCOM after the Korean War. As no transport network was available between the northern and southeastern areas, huge logistics hubs were built at ASCOM complexes. In 1972, ASCOM operations were phased down and in 1973 most of the ASCOM complex was turned over to the Republic of Korea Ministry of National Defense. All necessary support operations were moved to
Camp Humphreys. ==About the camp==
