OOM command battle droid/Legends

The Commander-class Battle Droid Officer (often called Battle Droid Commander or simply Command Officer)  was any B-1 battle droid of the Trade Federation and Confederacy of Independent Systems used for the purposes of transmitting orders from the Central Control Computer to squads of infantry battle droids or security droids.

Commanders were characterized by yellow markings on the tops of their heads and circular spots on their abdomens. They received long-distance signals allowing them to be far from base with their squads.
