As the new threat rose from Cobra, Hawk knew he would need some heavy artillery to take down the Improved B.A.T.s. The General sought out and recruited Repeater for re-enlistment.
While enjoying his retirement, Repeater couldn't stay away from things that go boom. Together with Lightfoot, they developed a new weapon system. A self generating caseless uranium shell forearm cannon. The new system (G.U.S.) was more powerful and more compact, enabling more maneuverability and firepower on the battle field. Perfect for destroying BATs and exacting a little revenge for his friend SCI-FI.
