Separatist battle droids

The Separatist Droid Army, otherwise referred to as the CIS Droid Army, Separatist Army, or the droid army, served as the ground forces for the Confederacy of Independent Systems' military during the course of the Clone Wars. Primarily constructed by the workers of Baktoid Combat Automata, the droid army was very largest of its kind in galactic history. The army was led by Kaleesh cyborg General Grievous, who held the title of Supreme Martial Commander of the Separatist Droid Armies, while also being commanded by Separatist leader Count Dooku. The Separatist Droid Army was more numerous than the Grand Army of the Galactic Republic. In addition, the droid army received additional reinforcements throughout the war, such as in 21 BBY, when they requested a supplemental amount of three million battle droids with financial assistance from the InterGalactic Banking Clan.
