Tag served as a clone trooper pilot within Shadow Squadron of the Republic Navy.
As a member of Shadow Squadron, Tag met his death during combat in the Battle of the Kaliida Nebula. The engines of Matchstick's BTL-B Y-wing starfighter/bomber, another pilot, malfunctioned, leading his damaged ship to collide with Tag's, resulting in their demise. Tag's gunner also perished in the crash.
