Worn today by personnel serving in he 394th Combat Sustainment Support Battalion, this Distinctive Unit Insignia was originally approved for the 394th Ordnance Battalion on 16 March 1970. It was redesignated for the 394th Support Battalion, with revised description and symbolism, with an effective date of 16 September 1995.
A black firebomb with flames reaching upward is a symbol of the combat readiness of the 394th Combat Sustainment Support Battalion. It also recalls the “bomb and shell” insignia of the Ordnance Corps and, along with the crimson background of the pyramid, pays homage to the time the unit spent serving as an Ordnance Corps unit. In the center of the firebomb is a simulated hawk eye, a reference to the state of Iowa’s nickname as the “Hawkeye State” and an allusion to the unit’s location there at the time the insignia was approved. “Mission Support Success” is the Battalion motto.
Also known as a unit crest or DUI, 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.
Full guidance on wear of the DUI is found in DA Pamphlet 670-1,
Section 21-22, "Distinctive unit insignia."
