Support Services was a department of the Alliance to Restore the Republic, established to give support to the rest of the Alliance. While not the most glamorous branch of the Rebel Alliance, it was crucial to their success in the Galactic Civil War. As a branch of the Alliance Military, Support Services was headed by one of the Supreme Allied Commanders, the Chief of Support Services. It worked closely with Ordnance and Supply; while Ordnance and Supply was responsible for procuring weapons, supplies, and equipment, Support Services was responsible for the physical transport of the items. The Ministry of Supply within the Alliance Civil Government also worked closely with Support Services.
