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 (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 305th Field Hospital Distinctive Unit Insignia was approved on 3 June 1971. Its focal point is a cross, longtime symbol for assistance and aid, centered inside an oval and colored red, white, and blue with gold trim. Besides incorporating our national colors, the cross’ colors and laurel also represent the Philippine Presidential Unit Citation which the unit was awarded following World War II.
That service in the Philippines is also represented by the palm tree, indigenous to the Philippines and a tree very important in the development of early civilizations. Magnolias on the arms of the cross are a reference to the state flower of Mississippi and a reminder that the unit was a member of the Mississippi Army National Guard.
Note: The 305th Field Hospital was inactivated in 1994 and it is unclear if was subsequently active at some point after that time. As of Autumn 2023, this unit does not appear to be active and may have been redesignated, reorganized, converted, consolidated with another unit, or inactivated.
