Ryan (World at War)

Private Ryan was a US Marine Raider under the command of seargent Sullivan. During a raid on Makin, he was grabbed by a burning japanese and fight with him in a melee combat. Just like private Roycewicz in Call of Duty 4, Miller (the player) has the choice to help him or let him burn with the japanese. The soldier's name is a reference to private Ryan from Spielberg's movie. Saving him on the Xbox 360 version unlocks an achievement called "Saved Private Ryan".
