After World War II, the Detroit Light Guards were reactivated, this time as the 425th Infantry Regiment, headquartered in Detroit, and assigned to the 46th Infantry Division, the "Iron Fist Division." On 15 March 1959, another reorganization took place, and the Detroit Light Guards were redesignated as the 225th Infantry Regiment, a parent regiment under the Combat Arms Regimental System, to consist of the 1st Battle Group, an element of the 46th Infantry Division. The 225th attempted to keep the peace during the 1967 Detroit riot, but the riots did much damage to the city, and the 46th Division was disbanded. The Detroit Light Guards, now simply the 1st Battalion, were transferred to the 38th Infantry Division on 1 February 1968.
