Commonly called a unit crest or DUI for short, the 349th Quartermaster Battalion Distinctive Unit Insignia (DUI), or unit crest, was approved on 21 December 1964 and was amended on 19 June 1989 to revise the description. It is topped by a wreath of olive branches, an image taken from the coat of arms of Reims, the French city where the Battalion was stationed in World War II. In addition to denoting the unit’s service location, the olive branches also commemorate the signing of the unconditional surrender of the German Army by General Alfred Jodl, the Wehrmacht’s Chief-of-Staff, on 7 May 1945. Superimposed on the olive branches is a turnstile, a method of controlling entry and exit. Here it is a reference to the Battalion’s wartime service of administering and operating a Prisoner of War stockade. “In Support” is the Battalion motto.

The 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.
Enlisted personnel wear the insignia centered on a shoulder loop by placing it an equal distance from the outside shoulder seam to the outside edge of the shoulder-loop button. Officers (except Generals) wearing grade insignia on the shoulder loops center the DUI by placing it an equal distance between the inside edge of the grade insignia and the outside edge of the button.
More guidance on wear of the DUI is found in DA Pamphlet 670-1, Section 21-22, "Distinctive unit insignia" and 21–3(d) and (e), "Beret" and "Garrison Cap," respectively.
Note: The unit for which this insignia is designated appears to have been inactivated, redesignated, disbanded, or consolidated with another unit and renamed.
