Roycewicz

Private Roycewicz (sometimes spawned in other levels with the rank of sergeant) was a US Marine under the command of Lieutenant Vasquez. During the attack on Al-Asad's capital city, Roycewicz and Paul Jackson were ordered by Vasquez to sweep and clear the second floor of a building they assaulted. While going up the stairs, Roycewicz was attacked by a particularly burly soldier, who knocked him down and shoots him. Jackson can choose to save him or watch him be killed. Usually, right when Jackson's squad enters the Bog, he is shot trying to get to cover.
