Super Battle Droid
this was a greatly-enhanced version of the basic B1-series battle droid produced by Baktoid Combat Automata for the Trade Federation. The original design, which mimicked the skeleton of a Neimoidian, lacked independent programming and had several pieces of sophisticated technology mounted externally. This meant that the basic battle droid needed a Droid Control Ship to receive orders, and that they were subject to damage in the field. The Super Battle Droid - designated the B2-series - was Baktoid's attempt to solve these design issues. The torso and upper body of the Supoer Battle Droid was beefed up with armor plating, inside of which the droid componentry was protected. A dedicated double laser cannon was built into the droid's right arm, and its manipulator arms could operate several other weapon types. The feet of the Super Battle Droid were detachable, allowing the droid to be fitted with grasping claws or magnetic units to operation in a variety of environments. Large numbers of these combat automatons were purchased by the Confederacy of Independent Systems for their own defense. With the end of the Clone Wars, all B2-series battle droids were issued orders to deactivate, as part of Darth Sidious' plan to consolidate military power and ensure the loyalty of his troops.
