The soldier assisted General Perez in evacuating the Auriga after the Cloned Xenomorphs on board escaped their containment cells. He was helping Perez launch the ship's lifeboats when the two witnessed a Xenomorph climb aboard one of the pods and began slaughtering its occupants. Perez ordered the soldier for his grenade, which he then threw into the escape pod before detonating it a safe distance from the ship, destroying it and killing the Alien within. Unfortunately for Perez, another Xenomorph then attacked him from behind, killing him while the soldier looked on in terror.
His fate afterward is unknown, but it is likely that he was also killed by the Xenomorph that killed Perez.
The soldier carried a remotely detonated grenade that he handed to Perez to destroy the Xenomorph in the escape pod.
