When Padawan Ahsoka Tano and Barriss Offee were sent into the Droid Factory to set charges on the main reactor, they were spotted by a Geonosian soldier, who reported them to his master, Poggle the Lesser. When he and the other Geonosians confronted the intruders in the reactor room, the B1 battle droids came into the room inside the Super tank, to reinforce the Geonosian soldiers. He and the other B1 battle droid commanded the tank and fired several shots at the two Padawan, but failed to hit them. When Ahsoka was knocked unconscious by the Geonosian soldiers, the two battle droids tried to run over her. He and the other battle droid were killed by Barriss Offee, who attacked the Super tank, slicing them in half with her lightsaber.
