46th Infantry Division (United States)

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.

The 1968 reductions of the Army National Guard, initiated by Defense Secretary Robert McNamara who felt that fifteen divisions were too many, reduced the division to the 46th Brigade (formed from the 2nd Brigade at Wyoming, Michigan), which was allocated to the 38th Infantry Division on 1 February 1968. The brigade was eliminated during Army restructuring in 2004.

Elimination of the division and 46th Brigade, 38th Infantry Division
The reductions of the Army National Guard, initiated in 1967 by Defense Secretary Robert McNamara who felt that fifteen divisions were too many for a reserve component, reduced the division to the 46th Brigade (formed from the headquarters of the 2nd Brigade at Wyoming, Michigan), which was allocated to the 38th Infantry Division on 1 February 1968. The division headquarters became the Michigan Army National Guard Emergency Operation Headquarters, while the headquarters of the 1st Brigade and that of the 1st Battalion, 225th Infantry became the headquarters of the non-divisional 1st Battalion, 225th Infantry. The headquarters of the 3rd Brigade and that of the 2nd Battalion, 225th Infantry became the headquarters of the non-divisional 46th Engineer Group (Construction), and the headquarters of the 46th Infantry Division Artillery became that of the non-divisional 157th Artillery Group, which included the 1st and 2nd Battalions of the 182nd Artillery.

The 46th Brigade gained the 1st Battalion, 125th Infantry, the 3rd Battalion, 126th Infantry, the 1st Battalion, 246th Armor, and Troop C, 1st Squadron, 238th Cavalry (the former Troop B, 1st Squadron, 146th Cavalry) for its maneuver elements. Its artillery battalion was the 1st Battalion, 119th Artillery, while Company D, 113th Engineer Battalion, Company D, 113th Medical Battalion, Company D (Forward Support), 738th Maintenance Battalion, and the 46th Brigade Administrative Section, 38th Administration Company formed its other support elements.

The 46th Brigade, 38th Infantry Division included the following units in 1970:


 * HHC, 46th Brigade, 38th Infantry Division (Wyoming)
 * 1st Battalion (Towed 105mm), 119th Artillery (Lansing)
 * 1st Battalion, 125th Infantry (Flint)
 * 3rd Battalion, 126th Infantry (Wyoming)
 * 1st Battalion, 246th Armor (Dowagiac with Detachment 1 at Three Rivers)
 * Troop C, 1st Squadron, 238th Cavalry (South Haven)
 * Company D, 113th Engineer Battalion (Wyoming)
 * Company A (Assault Helicopter), 38th Aviation Battalion (Grand Ledge)
 * Company D, 113th Medical Battalion (Detroit)
 * Company D (Forward Support), 113th Maintenance Battalion (Wyoming)
 * 2nd Platoon, 38th Military Police Company (Wyoming)
 * 2nd Light Truck Platoon, Company B, 38th Supply and Transportation Battalion (Wyoming)
 * 46th Brigade Administrative Section, 38th Administration Company (Wyoming)

In 1985 the Brigade, still headquartered at Wyoming, consisted of the 1–125 Infantry, the 3-126 Infantry, and the 1–225 Infantry.

As part of United States Army restructuring, the brigade headquarters was eliminated in 2004–2005, with the official inactivation ceremony on 1 October 2004. Its last commander was Colonel William Ewald. At the time, the brigade numbered 1,600 soldiers, and its 1st Battalion, 119th Field Artillery temporarily transferred to the 177th Military Police Brigade although it would see service with the 42nd Infantry Division during the War on Terror, while most units remained with the 38th Division.
