Tolentino was one of the Marines sent aboard the USS Sulaco to investigate the ship. Tolentino was one of the several Marines injured in the internal explosion aboard the Sulaco that occurred just as Cpl. Winter was attempting to board the ship via the umbilical from the USS Sephora. During the explosion Tolentino was heavily injured and an object had fallen on him which Private O'Neal moved aside. O'Neal then attempted to revive Tolentino but he ultimately succumbed to his injuries. O'Neal then whispered dammit and took Tolentino's M41A Pulse Rifle MK2.
