U.S. ARMY 91ST CIVIL AFFAIRS BATTALION UNIT CREST (DUI)

Headquartered at Fort Liberty (formerly known as Fort Bragg) in North Carolina, the 91st Civil Affairs Battalion is assigned to the 95th Civil Affairs Brigade and aligned with the United States Army African Command. It was constituted 25 June 1969 in the Regular Army as the 1st Civil Affairs Battalion and activated on Okinawa, where it served for the next several years until it returned to Fort Bragg and was inactivated on 39 June 1974.

Over thirty years would pass before the Battalion was redesignated as the 91st Civil Affairs Battalion on 14 March 2006 and activated two days later at Fort Bragg. While the Battalion as whole has not earned any military decorations since that reactivation, the exceptional service displayed by some of the Battalion’s companies have been rewarded with the Valorous Unit Award (Detachment, Company A and Company D) and the Meritorious Unit Commendation (Companies A and B).

The 91st Civil Affairs Battalion Distinctive Unit Insignia, commonly called a unit crest or a DUI for short, was originally approved on 13 January 1970 while the unit was still designated as the 1st Civil Affairs Battalion. It was redesignated for the 91st Civil Affairs Battalion with the description and symbolism updated on 14 April 2008.

The torii is an allusion to the Battalion’s initial service on Okinawa, with the winged crossbeam signifying the Battalion’s Airborne status. During that time, the Battalion’s mission scope included all of Southeast Asia, represented here by the rays of the golden sun. An unsheathed but horizontal sword symbolizes authority, and while the sword and scroll together are inspired by the Civil Affairs branch insignia, here the scroll is opened to denote actual performance of civil affairs in an overseas mission and to symbolize order and stability in government.

Unlike most Distinctive Unit Insignia, the 91st Civil Affairs Battalion does not feature the unit motto. It is the Latin phrase AUCTORES SOLIDI PRINCIPII, which translates into English as “Builders Of A Solid Beginning (Foundation).”

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.
