United Nations Command–Rear (also known as UN Command–Rear or UNC–Rear) is a rump military command headquartered in Japan, and a subordinate element of United Nations Command. UN Command–Rear was established in 1957 as a result of the relocation of UN Command from Japan to South Korea following the Korean War. It is nominally in control of the rear elements of what the United States and South Korea contend are United Nations military forces in northeast Asia.
