The 46th Infantry Division was a formation of the Michigan Army National Guard active between 1947 and 1968. It was initially headquartered at Lansing. Many of its units had previously been part of the 32nd Infantry Division. It was converted to the Reorganization Objective Army Division (ROAD) structure in March 1963. The Division's 2nd Brigade was assigned to the Selected Reserve Force, a higher-readiness component of the ARNG, in 1965. Virtually the entire division was involved in responding to the 12th Street riot in Detroit in July–August 1967.
