The 6th Infantry Division is a military formation of the Korean People's Army Ground Force. The date that the 6th Infantry Division was formed in somewhat unclear as the Army during the Korean War believed that the 6th ID was established either in July 1949 or March 1950. It is believed the division was formed at Sinuiju from 10,000 Chinese Communist Army personnel of Korean descent from the 166th Division who had been "repatriated" in late 1949 together with the former 1st Regiment of the 1st Division. The Korea Institute of Military History indicates that the division was established in October 1949. All sources indicate that the unit was initially composed of the 13th Infantry Regiment, 14th and 15th Infantry Regiments, and the 6th Artillery Regiment.
