Super Battle Droid

B2 Super Battle Droids are upgraded Battle Droid units with superior armor and armament for the Separatist Alliance.

Overview
Super Battle Droids are advanced battle droids who have a great capacity for independence and it's superior armor offer protection from enemy fire. Small fully-automatic dual laser cannons were mounted on their right forearms although some variations have their left forearms replaced with a rocket launcher. Their feet were also outfitted with specialized equipment for difficult terrain, such as climbing claws. Their arms also were modular, capable of exchanging laser cannons for other specialized weaponry.

As heavy infantry droids, Super Battle Droids can take much more punishment than their flimsy predecessors. Even after being defeated, they could detach their torsos and keep up an attack although this was detrimental to their combat skill.
