During the Clone Wars, Unit 4416 was a B1-series battle droid that fought for the Confederacy of Independent Systems. It was stationed on Tambor Deep Space Centre, where it aided Gorgol the Handy in repelling the Republic's siege. When it appeared the Republic forces were retreating, Gorgol dispatched two droid teams to check if the enemy had truly left. Unit 4416 commanded one of these teams and declared the left side was safe, but it was then promptly obliterated by Obi-Wan Kenobi, a Jedi Master.
