“Tech” was the nickname of a clone commando who served in the Grand Army of the Republic during the Clone Wars as a member of Clone Force 99. Due to his genetic mutations, he appeared leaner, fairer, and younger than his fellow clone troopers.
Tech served as the brains of his squad and was a valued asset in this regard, using his high intellect and mastery of technology to ensure their operations were successful. Even so, he was no less skilled in combat than the other three members.
While the squad was attempting to lose Imperial pursuit following a mission to Eriadu, Tech sacrificed himself to allow the others to escape.
