Tango Company was a unit of clone troopers in the Grand Army of the Republic. In the aftermath of the Second Battle of Geonosis, all of the troopers were infected with Geonosian brain worms, resulting in a skirmish aboard Republic medical frigate TB-73 with Jedi Commanders Ahsoka Tano and Barriss Offee.
Following the Second Battle of Geonosis, the Grand Army of the Republic's Tango Company was assigned to escort TB-73—a medical frigate under the command of Jedi Commanders Ahsoka Tano and Barriss Offee—to the Ord Cestus medical station. However, clone trooper "Scythe" was infected with a Geonosian brain worm and secretly brought a batch of eggs aboard the starship. On board the medical frigate he caused the infection to spread to other clones, including "Edge," "Havoc," "Ox," "Pulsar," and Clone Lieutenant "Trap." Burrowing within the brains of the infected soldiers, the worms controlled their hosts' actions and forced them to attack the Jedi. As the worm infestation spread to the rest of the ship's crew, infecting Offee in the process, Tano attempted to regain control of the vessel before its arrival at Ord Cestus. Ultimately, she prevented the infection from spreading to the medical station by deactivating the frigate's climate control, thereby causing the worms to lose control of their hosts as they froze to death.
