U.S. ARMY 30TH AIR DEFENSE ARTILLERY BRIGADE UNIT CREST (DUI)

The 30th Air Defense Artillery Brigade Distinctive Unit Insignia, also called a unit crest or DUI, was approved on 13 April 1966. It features a blue fleur-de-lis that represents the unit’s service in France during World War, while a red torii gate is emblematic of Okinawa, the location where the Brigade was reactivated. The golden arrow's positioning in the center of the insignia is a reference to the unit motto, "Always On Target."

Distinctive Unit Insignias are 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. Current regulations do not permit the DUI to be worn on the Dress variations of either uniform, however.

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.
