During the Clone Wars around 21 BBY, this T-series tactical droid commanded a Separatist supply ship during a battle on the planet Umbara. The ship was supplying the Umbarans, creating hardships for the Republic. The droid was destroyed along with the supply ship when Umbaran starfighters commandeered by clone troopers flew into the ship's hangar, and blew up the main reactor.
