Martin

Private Martin is an American soldier in Call of Duty, and one of the three protagonists in the game. He is a member of the 506th Parachute Infantry Regiment of the 101st Airborne Division, as a pathfinder under Cpt. Foley's Baker Company. As a protagonist, he journeys with the rest of Baker Company on all of their military operations, presumably until the end of the war. Although Captain Foley is transferred to a different company as refrence to Call of Duty: United Offensive

Despite being a lowly private, Martin is relied on heavily as something of a dedicated explosives expert, destroying several German equipment through stolen Panzershrecks and TNT. As a pathfinder, he was capable of setting up radio beacons. He also had training as a sniper at Camp Toccoa, and is typically designated as the person who collects sensitive documents as shown in the Brecourt Manor, Chateau and Battle of the Bulge missions. Contrary to popular belief, oddly Pvt. Martin does not die in Bastogne after being wounded and later hit by artilery (in an attack that happened in late December) due to the fact that the Player takes control of him on January 1945.

You, the player, control him, so he doesn't have a specific weapon. He is the first soldier played in the Call of Duty game series, and is the trooper that you go through training with.

Trivia
