These are the playable characters in Call of Duty 4: Modern Warfare (Nintendo DS): The Nintendo DS version focuses less on the main attempts to end the conflict and more on the supporting role of the various other soldiers who played a part in the war. Instead of going after the main antagonists of the overall plot (even though they are mentioned) (the Four Horsemen: Russian Ultranationalist Imran Zakhaev and his allies), the playable characters in the Nintendo DS version participate in minor missions, such as escaping from an American Marine base in the Middle East as it is attacked by enemy forces, or raiding two cargo ships in the stormy, black, dark Baltic Sea which may be carrying nuclear materials. Unlike the console and PC version of Call of Duty 4: Modern Warfare, players do not directly impact the outcome of the war. The Nintendo DS version of the game allows the player to assume the roles of several anonymous soldiers, who are either affiliated with the British S.A.S.
