A OOM-Battle Droid Commander

OOM-Battle Droids were the first series of battle droid created by Baktoid Combat Automata. They were mostly used by the Trade Federation and other independent fractions in the years before the Clone Wars. Unlike their eventual replacements, the OOM Battle Droids had less independent thinking skills, due to their manufactures thinking that they would preform better without any free thinking. The droids that followed after them, the B1 units, were clumsy and less reliable than the original OOM droids. Despite the line of droids being shut down, OOM droids were still used by the Separatists and were considered to be some of the better droids in the army.
