The infantry used by the Trade Federation had several major shortcomings that were carefully revisited by the battle droids' designers. From that research came the super battle droid, a bulkier, stronger, and more advanced version of the standard mechanical soldier. The super battle droid requires no overriding command signal to operate, and thus has a limited degree of independence. They are fearless and tireless, and will run at full speed into combat, their cannons extended, firing until they have reduced their targets to smoldering ruins.
