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