ARC-77, known as "Fordo," was an Alpha-class Advanced Recon Commando captain in the Grand Army of the Republic. 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. 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.
