Roycewicz

Priate Roycewicz 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 began choking him. However, Jackson was right behind Roycewicz and was able help him, killing the soldier and saving Roycewicz. Unfortunately, Roycewicz was likely killed later in the campaign.

Roycewicz was named after a member of Call Of Duty 4's development team. Saving him on the Xbox 360 version unlocks an achievement.
