The “B2 Super Battle Droid” was a more up-to-date model of the B1 droid, serving in the Confederacy of independent systems during the start of the Clone Wars. The B2 Superdroid had various arsenals in its wrists or arms that could adapt various weapons such as: a blaster, a cannon or claws that expanded its combat function.
The B2 like many other droids had a very limited processor to evaluate strategies for this reason an organic commander or a tactical droid was required to operate effectively, their thick armor gave them greater resistance and strength to take down a clone trooper.
Despite their fire and armor potential, the B2s remained as additional reinforcements for the classic B1s that outnumbered 100 to 1 with other types of droids. When the Empire seized the reins of the Galaxy all Separatist droids were dismantled or sent to foundries, the few surviving B2 models were sold as escorts in underground markets.
