The 332nd Ordnance Battalion Distinctive Unit Insignia, also known as a DUI or “unit crest,” was approved on 23 July 1971. Unlike the vast majority of unit crests, it does not display the unit motto.
According to the much-respected book U.S. Army Heraldic Crests: A Complete Illustrated History of Authorized Distinctive Unit Insignia by Barry Jason Stein, the arrow is a traditional symbol of war, and coupled with the two black grenades—adapted from the branch insignia for the Ordnance Corps—is a reference to the organization's participation in the Central Europe and Rhineland campaigns in World War II. However, the U.S. Center of Military History credits the 332nd Ordnance Battalion with an additional campaign, the Ardennes-Alsace, during the war. The Battalion also served Occupation duty in Germany from 2 May to 14 August 1945.
Headquarters and Headquarters Detachment, 332nd Ordnance Battalion was originally constituted in the Army of the United States on 25 February 1943 and activated 30 August 1943 at Camp Bowie, Texas. After serving in Europe during World War II, the Battalion was inactivated in November 1945 at Camp Hood, Texas. It was allotted to the Organized Reserves—precursor to today’s Army Reserve—in early February 1947 and activated on 21 February 1947 at Watertown, New York.
On 31 January 1968, the Battalion was redesignated as Headquarters and Headquarters Company, 332nd Ordnance Battalion. It was relocated to Huntington, West Virginia in September 1994 and to Kenova, West Virginia in June 1996. When it was deactivated in August 2010, it was assigned to the 316th Expeditionary Sustainment Command, United States Army Reserve. Its current status (Spring 2023) is uncertain, but it is nowhere to be found on the official Army Reserve Web site.
