The 702nd Support Battalion Distinctive Unit Insignia (DUI), or unit crest, was originally approved for the 702nd Ordnance Battalion on 21 August 1954. Its five fleurs-de-lis in the upper right denote the number of campaigns the unit took part in during World War II in the European Theater, while the blue bend is the colors of the Korean Service Medal: As the 702nd Ordnance Light Maintenance Company, the unit took part in numerous campaigns in Korea and was awarded two Meritorious Unit Commendations and a pair of Korean Presidential Unit Citations. “Mend The Broken Sword” is a reference to the Battalion’s Ordnance Maintenance duties.
Following the Korean War, the Battalion was redesignated as the 702nd Maintenance Battalion on 4 April 1963 and later was redesignated as the 702nd Support Battalion, operationally called a Main Support Battalion and then the 702nd Brigade Support Battalion in 2005.
There is no readily available public information regarding the status of this unit at the time of this writing (Autumn 2023). It appears to have been inactivated, deactivated, converted, or redesignated at some point in late 2014 or early 2015. Its last known assignment was to the 4th Stryker Brigade Combat Team, 2nd Infantry Division.

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 (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.
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.
