During the Galactic Republic attempt to liberate the planet's capitalcity of Lessu, the command droid led his tanks against a column of All Terrain Tactical Enforcers of the Grand Army of the Republic. When the Republic walkers were moving forward in a winding road above a canyon, the AATs attacked them from the other side of it. The command droid entrenched into a small bunker with his B1 battle droidadjutant, where they could oversaw the assault. After his AATs managed to cripple the first AT-TE, which blocked the way from the rest of the walkers, the droid ordered his tanks to also cripple the rear units of the AT-TEs, hoping to trap the column on the road. However, Jedi MasterMace Windu, the leading general of the Republic forces, was able to Forcepush the crippled AT-TE out of the road, and led the clone troopers of the Lightning Squadron against the AATs with the All Terrain Recon Transports. Noticing the Jedi's counter-attack, the command droid ordered his tanks to destroy the squadron, but the walkers proved to be too fast to be shot. The droid considered to surrender with his aide, but the attack had already reached the droid's bunker, and Windu destroyed both droids with the laser weaponry of his AT-RT. The droid's tanks were defeated shortly after as well.[2]
A battle droid with a masculine personality, this OOM-series commander droid was in charge of a group of AATs. When his aide, who was equipped with an electrobinoculars, reported about the actions of the Republic forces, the command droid wanted to see the events himself before giving any orders, and borrowed the electrobinoculars twice during the battle. His tactic was to trap the Republic walkers into the road above the deep canyon by disabling both the first and the last AT-TE, preventing the rest of the walkers for advancing and leaving them to be destroyed by his tanks. However, he did not count the Force powers of Jedi Master Windu, who managed to clear the road. When Windu led the Lightning Squadron against the droid's AATs, the droid immediately identified him as a Jedi, and ordered his tanks to eliminate the attackers. When the walkers evaded the tanks fire and approached the two droids, his adjutant asked should they escape, but the command droid thought that a surrender would be a better option, though he failed to achieve it when he was gunned down with his aide.
