The Separatist Droid Army, also referred to as the Separatist Army, droid army or as the droid armies, was the ground army force of the Confederacy of Independent Systems during the Clone Wars, and was part of the Confederacy military. The army was mostly built by Baktoid Combat Automata and led by the Kaleesh cyborg General Grievous. According to Count Dooku, Head of State of the Confederacy, at the start of the conflict in 22 BBY the Droid Army out numbered the Republic’s clone army one hundred to one. In addition to this opening amount of droids, the Separatists continued to produce droids throughout the war, and one example was in 21 BBY when they ordered more than three million battle droids with the InterGalactic Banking Clan helping to finance this order. The army was deactivated after the Clone Wars, when Darth Sidious rose to power as Emperor of the Galactic Empire.
