Battle droid assassin

The battle droid assassin was a variation of the B1-series battle droid used by the Trade Federation and the Confederacy of Independent Systems over the course of the the Clone Wars. Their gyroscopic stabilizers and detailed target-selection programs made them very effective snipers, which proved lethal to the Galactic Republic's clone troopers. They were not, however, as common as the regular B1 battle droids, because it was costly to make a droid as accurate as an organic sniper could be.

During the Clone Wars, battle droid assassins were deployed at the Battle of Geonosis in defense of the most important units waiting to be loaded onto transports and at the Battle of Muunilinst against Advanced Recon Commandos. Battle droid assassins were also used during the Battle of Tirahnn, and appeared on a number of battlefronts throughout the Clone Wars. Following the end of the conflict and the shutdown of the Separatist Droid Army, battle droids were reactivated and used by the rogue Geonosian Gizor Dellso in his army up until the Battle of Mustafar.
