Umbaran Commanders were responsible for leading groups of Umbaran soldiers into battle and were a large asset in the Umbaran militia for the Separatists. CT-1312 and the Midnight Ops. were tasked on destroying these powerful enemies. The 45th Elite Legion were also tasked on destroying Spike, an Umbaran Commander.
Most Umbaran Commanders wore the normal Umbaran armor but with blue markings on it, and the Umbaran alphabet leter "C" for commander on the shoulder. They used Umbaran blaster rifles but could and did use rocket launchers and mini-sized versions of the energy guns on the Umbaran Tanks.
