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 (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.
The dark blue and scarlet used for the 28th Personnel Services Battalion Distinctive Unit Insignia are colors long associated with Personnel Services units, while red symbolizes zeal and vitality and gold stands for excellence and ideals. A pair of arrowheads allude to the unit’s service in World War II and the two assault landings in which it took part, and the fleur-de-lis is a reference to service in France during the First World War. Two swords reinforce the unit motto of “As Mighty As The Sword;” they are crossed to suggest support and strength.

Since its inception in September 1916 as the Machine Gun Company, 4th Infantry Regiment, the unit we know today as the 28th Personnel Services Battalion has undergone a twisted path that has seen it designated as a Machine Gun Battalion, Infantry Battalion, Antiaircraft Artillery Battery, Coast Artillery Battery, Antiaircraft Automatic Weapons Battery, Signal Detachment, Data Processing Company, and an Adjutant General Company. It was not until 1993 that it was designated as a Personnel Services Battalion.
The 28th Personnel Services Battalion is no longer an active unit.
