What is a Unit Crest?
Unit Crests, or "Distinctive Unit Insignia" (DUI), are worn by United States Army soldiers and are designed by the U.S. Army Institute of Heraldry
. These enamel metal insignia are worn by US Army enlisted personnel and officers on the shoulder loops of the green service uniform jacket. The unit crest is also displayed on the beret flash. In the past, ceremonial units were often authorized to display the unit crest on the Army dress blue uniform. All US Army elements listed in AR 670-1
with at least 500 personnel
have a DUI assigned to them. Army National Guard units are authorized
to display the crest of the state assigned to them.
