Tenn was a clone trooper stationed in the ops room of the Acclamator-class Assault Ship Fearless. He was the principle weapons officer. He aided Etain Tur-Mukan and Clone Commander Gett in planning the rescue of Omega Squad by finding the optimum fire solution as Fearless decelerated out of hyperspace. Tenn fired two torpedos at a Separatist ship, destroying it and saving Delta and Omega.
