Sarge participated on the Losers' mission in Operation Four Horsemen in rescuing Colonel Richard Flagg and his squad on the once uncharted Dinosaur Island. Upon violently arriving on the island, Sarge and the losers were beset by a tyrannosaurus rex. He helped his close friend Gunner in killing the dinosaur with a bazooka, but only to witness Gunner's death. Sarge was greatly devastated of Gunner's death and personally buried him outside of Colonel Flagg's cave hideout.
By the next morning, Sarge went on his own in avenging Gunner's death by killing the T-rex with a bazooka. When Johnny Cloud went back to the cave and find Colonel Flagg, Flagg told Cloud that he saw Sarge attempting to kill the T-rex and was dead in his efforts.
