Also known as a unit crest or DUI, a Distinctive Unit Insignia is worn by all Soldiers (except General Officers) in units that have been authorized to be issued the device. It is worn centered on the shoulder loops of the Army Green Service Uniform (AGSU) and the blue Army Service Uniform (ASU, Enlisted only) with the base of the insignia toward the outside shoulder seam. DUIs are not worn on the Dress variations of either uniform, however.

The 89th Regiment Distinctive Unit Insignia was initially approved for the 341st Field Artillery Regiment on 22 May 1926. It was redesignated the first time on 28 September 1942 for the 341st Field Artillery Battalion, and again on 29 January 1962 for the 89th Regiment. In September 1985, the insignia was amended to include in the symbolism description the states from which personnel were originally drawn.
A scarlet background is employed to reflect the Regiment’s origins in the Artillery branch of the Army as the 341st Field Artillery. A goldenrod in the lower portion reflects the unit’s association with the 89th Division (the goldenrod is the state flower of Nebraska). A Loraine cross beside the goldenrod stands for service in the Lorraine region during World War I. The blue chief (upper third) features a mountain rising from a plain as a way to denoting the three states—Colorado, Missouri, and Southern Dakota—from which personnel were drawn to form the 341st Field Artillery Regiment.
The 89th Regiment is a disbanded Regiment that was an organic element of the 89th Division (Training). At one point, the unit was designated as the 89th Regiment (Common Specialist Training). There is no data on readily and freely accessible public Internet sites regarding the unit’s inactivation or disbanding, although information from The Institute of Heraldry suggest it came at some point after 1985 since that was the year its insignia’s symbolism description was amended.
