OOM 9

OOM 9 was built by Backtoid Combat Automata, and served in the Trade Federation droid army. He was the Commander Battle droid who was selected for leading the droids into invading Naboo, under the orders of Viceroy Nute Gunray.

Occupation
OOM 9 was constructed to serve in the Trade Federation droid army, under the command of Viceroy Nute Gunray alongside with his staffs, Rune Haako and Lott Dod. OOM 9 was one of the several Commander Battle droids leading the Trade Federation forces on Naboo. His first assignment was to organize his troops for his mission to invade the planet, Naboo and turn it into Trade routes. During his destruction of Naboo's swamps to take out the Gungans, he was informed that Quin Gon Jinn and Obi Wan Kanobi escaped to Naboo.

Early battles
OOM 9 was selected for the mission of destroying Naboo's communication buildings. He led the mission with his small force of STAP's, Battle droids and Beetle droids and his Assault Armoud Tank, but was ordered not to create Major battles until reinforcements arrive. He soon destroyed the communications and prevented Naboo to call for help from the Republic.

Capture of the capital
OOM 9 eventually captured Naboo's captital city along with Queen Armidala. When Nute Gunray and Haako arrived, OOM 9 showed his masters to the Palace and Queen Armidala captured. The droid soon ordered one of the Secuirity Battle droids to transport the Queen.

Fighting the Gungan army
OOM 9 led his troops into fighting the Gungan warrior's, he ordered the AAT's to attack but the tanks was unable to destroy the shield. So OOM 9 sent his Battle droids into fighting the Gungans inside the shield. Droideka's later destroyed the shield, and AAT's joined the fight.

OOM 9s army was victorious as the Gungans began surrendering. Although, thanks to the young Anakin Skywalker's pilot skills, the droid Command ship was destroyed. The Trade Federation droids on the Grassy Plains deactivated including OOM 9.
