"The Military Surface Deployment and Distribution Command [SDDC] is a unique Army command that delivers world-class, origin-to-destination distribution solutions. Whenever and wherever Soldiers, sailors, airmen, Marines and Coast Guardsmen are deployed, SDDC is involved in planning and executing the surface delivery of their equipment and supplies. SDDC is the Army Service Component Command of the U.S. Transportation Command and is a major subordinate command to Army Materiel Command. This relationship links USTRANSCOM's [United States Transportation Command] Joint Deployment and Distribution Enterprise and AMC's Materiel Enterprise. The command also partners with the commercial transportation industry as the coordinating link between DOD surface transportation requirements and the capability industry provides."
