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.
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.

The 211th Aviation Group Distinctive Unit Insignia, also referred to as a unit crest or DUI, was approved on 1 August 1988 and prominently features the ultramarine blue and golden orange hues that are used for Aviation units. A stylized mountain range in the center of the insignia is a reference to the state of Utah, the home location of the Group as a member of the Utah Army National Guard, with silver lightning flashes suggesting snow-capped peaks. The lightning is also a reference to the unit motto, “Swift Sure Deadly,” inscribed on a scroll encircling the base of the mountains as an embodiment of the capabilities of the Group when tasked with aerial attack.
As of Autumn 2023, the Group is not listed in the Annual Report of the Utah National Guard and does not appear to be active.
