It is described as "a silver device 1 inches in height overall consisting of a blue arrowhead on which is superimposed a silver lion." The blue arrowhead and silver lion come from the brigade's two original regiments, the 26th Infantry Regiment ("Blue Spades") and the 28th Infantry Regiment ("Black Lions"). Since both the 1st and 2nd Brigades of the 1st Infantry Division were formed before the division, they are authorized their own DUI.
