The three points of the stylized caltrop symbolize resolve, spirit and professionalism. The silver disc voided by a triangle represents unity; the triangle alludes to stability and strength. The gear wheel underscores efficient support to United States soldiers around the world and industrial operations. The bomb highlights the ordnance mission; the globe represents the scope of the missions and field sustained support. The sword refers to combat readiness and the organization's support to soldiers. The reversed chevron symbolizes Command's provision of a single point of entry for all Army Materiel Command units to Army Field Commanders.

The distinctive unit insignia was originally approved for the U.S. Army Operations Support Command on 20 July 2000. It was redesignated effective 1 October 2006, with the symbolism updated, for the U.S. Army Sustainment Command.
