The 80th Training Regiment Distinctive Unit Insignia, commonly called “unit crest” or a DUI for short, was first approved for the 905th Field Artillery Battalion, Organized Reserve on 26 February 1943. It was redesignated for the 80th Regiment, Army Reserve on 16 August 1960, with amendments made to correct the motto on 19 June 1968. NUNC UT OLIM, the unit motto, is Latin for “Now As Before,” denoting the continuance of successful operations.
Constituted as the 155th Field Artillery Brigade and assigned to the 80th Division on 5 August 1917, today’s 80th Training Regiment began its service life with combat action in the Meuse-Argonne offensive near the end of World War I. Demobilized in June 1919 and reconstituted two years later in the Organized Reserve as Headquarters and Headquarters Battery HHB, 155th Field Artillery Brigade and again assigned to the 80th Division, it was organized in December 1922 in Washington D.C.
Twenty years later, it was reorganized and redesignated on 12 February 1942 as HHB, 80th Division Artillery and ordered into active military service on 15 July 1942. It served in four World War II campaigns—Norther France, Rhineland, Ardennes-Alsace, and Central Europe—before returning stateside to be inactivated in January 1946 in New Jersey. It was redesignated as HHB, 80th Airborne Division Artillery on 15 July 1946 and activated 12 March 1947 in the Organized Reserves, which became the Army Reserve in 1952, the same year it was redesignated as HHB, 80th Division Artillery.
In March 1959, the unit’s purpose changed entirely when it was reorganized and redesignated as Headquarters and Headquarters Company, 80th Regiment, an element of the 80th Division (Training). In 1968, two battalions were added to the Regiment, both elements of the 80th Division (Training); the 3rd Battalion was added in 1994, then removed in 1995. In 1996, the Regiment was reorganized with a total of eleven battalions, each an element of the 80th Division (Training) (although some of these elements have been called into service for the War on Terrorism). In 2006, the 10th and 11th were reassigned to the 104th Division (Institutional Training), the start of a number of reassignments for the Regiment’s battalions.
As of Summer 2023, active elements of the 80th Regiment are assigned to Brigades of the 94th Training Division at Fort Lee, Virginia, where they assist in training in the three branches of the Logistics Corps: Quartermaster, Transportation, and Ordnance.
