R2-D2's battle droid squadron

"R2, look out! Behind you! You're being followed by battle droids!"

- C-3PO upon seeing the squad.

A squadron of battle droids was used by the Galactic Republic during Clone Wars. The units had been captured by the Republic and reprogrammed to serve it, participating in a mission to free Jedi Master Even Piell from the Confederate prison known as the Citadel. During the ensuing battle, all units were destroyed when they were ordered to cover the retreat of the rest of the team.
