The 50th Financial Management Support Unit Distinctive Unit Insignia—commonly called a “unit crest,” or simply DUI for short—was approved on 21 April 1997. Its primary colors, silver gray and golden yellow, are the branch colors of the Finance Corps. Combined with golden yellow, the insignia’s other two colors, blue and red, recall the unit’s history with Armor units. In heraldry, gold is always used to indicate excellence and here reinforces the unit motto of “Financial Excellence.”
A red diamond in the center is actually a mascle, the heraldic term for a lozenge with a lozenge-shaped hole in its middle; it is adopted from the branch insignia of the Finance Corps, and the sword inserted through it is a reminder of the unit’s combat service support function. Together, the sword and mascle emphasize teamwork in accomplishing the Finance Corps’ mission. The demi-disc on which the motto appears is an allusion to coinage and other monetary responsibilities. Silver and golden rays emanating from the base of the insignia’s shield symbolize the distribution of money and the offer of financial support to Soldiers.
The 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. 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.
