The 516th Personnel Services Battalion Distinctive Unit Insignia, a device also called a unit crest or DUI, was discontinued following the inactivation of the Battalion in December 2006, the direct consequence of the inactivation of the organization’s parent unit, the 8th Personnel Command. A pair of quill pens, nibs down, symbolize the unit’s primary function as an administrative unit, while the upright sword denotes the Battalion’s dedication to maintaining combat effectiveness, a crucial quality for any Army unit stationed in Korea. “Raise Up Higher” was the Battalion motto.
Headquartered at Yongsan Garrison and with detachments stationed at Camp Humphreys and Camp Henry, the Battalion was originally organized under a Table of Organization and Equipment with an effective date of 16 October 1987. Besides the aforementioned detachments, the Battalion’s D Company was tasked with the processing and distributing all mail arriving for units in Korea, with postal platoons carrying out this mission based at Camps Humphrey and Henry as well as Yongsan Garrison and Kimpo Airport.

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 (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.
For Enlisted personnel, the insignia is 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.
