Unit 4432 was a B1 battle droid in service of the Confederacy of Independent Systems during the Clone Wars. Stationed aboard Tambor Deep Space Centre, it assisted Gorgol the Handy in defense against Republic siege. After the Republic forces seemingly broke for a run, Gorgol assigned two droid squads to investigate if their enemy was really gone. Unit 4432 led one such squad and reported the right flank to be clear, moments before being destroyed by the Jedi Master Mace Windu.
