More often referred to as a "unit crest," the Distinctive Unit Insignia (DUI) of the 143rd Sustainment Command is a symbol of the unit’s duties and heritage. It was originally created in 1969 for the 143rd Transportation Brigade, but it was redesignated and its description amended when the unit became the 143rd Transportation Command in 1985. In 2007 the unit took on its current designation of the 143rd Sustainment Command the crest was redesignated a final time, this time with both the description and symbolism updated.
The colors of gold and red that are present are indicative of a unit with the Transportation designation and recall the unit's history between 1969 and 2007. The green in the center of the crest actually alludes to a green streetlight, meaning “all traffic forwards”, another reference to the previous designation of the unit. The shape of the crest, that of an annulet, simulates both a wheel, which is indicative of motor transportation, and an enclosure, which symbolizes a terminal. Both of these refer to the mission of the 143rd— to redeploy allied forces, manage theatre distribution, and planning, coordinating, and leading operation sustainment.
The wings on both sides of the crest are a reference to the 143rd’s air transport abilities and also an allusion the speed at which the Command conducts its operations. The arrow that vertically bisects the crest symbolizes the controlled direction of the organization; it is also a symbol of the 143rd Sustainment Command's readiness when it comes to battle.
