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 (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 726th Finance Battalion Distinctive Unit Insignia—better known to most Soldiers as a “unit crest” or DUI—was authorized on 30 April 1996. Prominently displayed in the shield portion of the insignia are the two branch colors of the Finance Corps, golden yellow and silver gray. Also on the shield is black, denoting solvency (it is also used for the scroll), and blue from the Massachusetts State flag (the 726th Finance Battalion was a unit in the Massachusetts Army National Guard). Besides serving as a branch color, gold is also a symbol of high achievement and excellence.
A diamond in the center is adapted from the Finance Corps insignia of branch, and the powder horn inside it commemorates the state’s Revolutionary War history and heritage. The golden, double-warded key, is a symbol of security, reinforcing the first half of the unit motto: “Pay Ensured.” The second half, “Fit To Fight,” is symbolized by the two crossed swords behind the diamond; they also represent readiness and teamwork.
