The Protodeka saw action on Raxus Prime and Thule, where they defended both Count Dooku and the ancient Sith city of Kesiak, which contained the Dark Reaper. They were destroyed by Obi-Wan Kenobi on Raxus Prime, and Mace Windu and Luminara Unduli on Thule, where each of the victors utilized the TX-130 Saber-class fighter tanks to win their respective battles against the droid tank.
Designed to turn the tide in favor of the Confederacy, the Protodeka turned out to be too expensive to mass-produce, so only a few were built. Following the end of the Dark Reaper campaign, the Colicoid engineer who designed the Protodeka was imprisoned within the Fortress of Axion.
Following the execution of the Separatist Council by Darth Sidious's new apprentice, Darth Vader, any remaining units were deactivated.
