This Training Droid unit was much like the B1 Training Droid, but was created to look like the B2 Super Battle Droids that were used by the Separatist Alliance. They were used to train clone cadets on how to survive a combat situation during the ongoing war. The B2 Training Droid was also used to show a clone cadet the weak spots of a real B2 Super Droid, with the weak spots marked with orange targets. Like all Training Droids, there wrist blasters only stun people, not kill them like real battle droids.
