The 318th Transportation Agency Distinctive Unit Insignia, more commonly referred to as a “unit crest” or a DUI, was approved on 7 June 1993. In its center is a gold fleur-de-li surmounted on a disc of wavy blue and white bars to commemorate World War II service in France and the Rhineland, respectively. Beneath the disc are a pair of crossed scimitars that recall the activation of the 318th Transportation (Movement Control) in September 1990 and its subsequent service throughout the remainder of Desert Shield and Desert Storm, where it function as the de facto “Theater Army Movement Control Agency.”
An arched scroll rendered in brick red with yellow script used for the motto, “Moving The Force” incorporates the colors traditionally associated with the Transportation Corps. The laurel at the insignia base is in honor of the Agency’s Meritorious Unit Commendation it received for service during Gulf War. The gear teeth on the outside of the disc containing the blue and white wavy bars symbolizes the mobile power and force on land, in the air, and on the sea.

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. DUIs are not worn on the Dress variations of either uniform, however.
Full 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.
