The 68th Combat Sustainment Support Battalion Distinctive Unit Insignia, also called a unit crest of just DUI for short, pays homage to both the Quartermaster branch (the blue ring invokes the Quartermaster insignia wheel) and the Transportation Corps (the brick-red ring), both of which the unit has served in since it was constituted as the Headquarters, 2nd Battalion, 45th Quartermaster Regiment (Truck-Army) in 1936. Two arrows stand for the India-Burma and Central Burma campaigns in which the unit participated in World War II, and the wavy arrow lines symbolize the tortuous Burma Road; they also convey the idea of points of departure and arrival. The unit motto “Wheels Of Distinction” display the unit's pride in successfully providing combat support under even the most arduous conditions.
