In the Unit Crest (Distinctive Unit) insignia of 4th Sustainment Command
, we find two find scimitar handles separating the words of the unit's motto, “Leaders In Logistics;” these represent the Command's two campaigns ribbons (Defense of Saudi Arabia and the Liberation and Defense of Kuwait). The four sections of the square, which itself recalls a shipping container holding the materiel necessary for warfighting, are a nod to the unit's numerical designation (much like the four arrows in the Command's CSIB, or Combat Service Identification Badge
). A flame at the top of the crest is a symbol of leadership guiding the way for successful combat.
