Battle droids, also known as combat droids, clankers, droid soldiers, or battle bots, were a type of droid designed for combat. Over the years, many different models of battle droid were being utilized by various factions throughout the galaxy. One such faction was the Confederacy of Independent Systems, which used a number of different models of battle droid during the Clone Wars to make up the Separatist Droid Army. Under the command of General Grievous, varying models of battle droids fought against the Galactic Republic's clone troopers until the final days of the war, when the Confederate battle droids were deactivated by the Galactic Empire.
