The 18th Division was an infantry division in the III Corps of the Army of the Republic of Vietnam (ARVN). The U.S. Military Assistance Command Vietnam considered the 18th as undisciplined and was well known throughout the ARVN for its "cowboy" reputation. In 1975 the 18th was made famous for its tenacious defense of Xuân Lộc, the last major battle before the Fall of Saigon.
