Making their way to the Jedi's location, Fordo and his men battled Grievous, but were unable to kill him. Immediately after the battle was over, Fordo was dispatched to the planet Hypori, where a group of Jedi Knights had been trapped by the Confederate General Grievous.
Together with a group of clone troopers that would later come to be known as The Muunilinst 10, Fordo proved instrumental in the Battle of Muunilinst, leading his troops to destroy an enemy artillery emplacement, and then helping Kenobi capture the enemy leader, San Hill. In 22 BBY, he was assigned to a task force led by the Jedi Knight General Obi-Wan Kenobi, to take the Confederate-held world of Muunilinst. ARC-77, known as 'Fordo,' was an Advanced Recon Commando captain in the Grand Army of the Republic.
