Tom Sullivan

Seargent Tom Sullivan was an American squad leader of the United States Marine Corps in Call of Duty: World at War during World War II.

Tom Sullivan was the leader of the Marine Raiders squad that came to rescue private Miller (the player) at the beginning of the game, on Makin. After Roebuck knifed Miller's assailant in the back, Sullivan hands Miller a Nambu pistol and assaults the Japanese base. They rescue their support squad and foil two ambushes staged by the Japanese and leave the island. Sullivan then leads Roebuck, Miller, Polonsky and several others on an assault on Peleliu Island. They make way for an Allied landing force, but Sullivan is killed when a Banzai Charger impales him through the stomach with a katana his assailant is quickly gunned down by Roebuck, Polonsky and Miller. Everyone was stunned by Sullivan's death, Roebuck especially. He refers to Sullivan as "the most solid, dependable and courageous Marine we've ever known." Polonsky also mourns Sullivan's death, lamenting, "I thought Sullivan would make it through for sure." At the start of Hard Landing, we learn that Sullivan's body is being sent back to his family and Roebuck is promoted to Sergeant and takes command of the squad.
