- "Outstanding, Marines, out fucking standing!"
- — Tom Sullivan
Tom Sullivan was the leader of the Marine Raiders squad that came to rescue Private C. Miller (the player) at the beginning of the game, on Makin. After Roebuck knifed Miller's assailant in the back, Sullivan strangles the Japanese officer and hands Miller the officer's Nambu pistol and assaults the Japanese base. They rescue their support squad and foil two ingenious ambushes staged by the Japanese and leave the island.
Towards the end of their assault, Sullivan saves a shell-shocked Miller from a Katana wielding Japanese soldier and drags him to the lifeboats. Two years later Sullivan, Roebuck and Miller are part of the 1st Marine Division along with many new recruits, including Pvt. Polonsky. Miller, Roebuck and Sullivan are known as the 'old breed' by the recruits although none of the three were out of their twenties yet. Sullivan's squad and the 1st Marine Division assault Peleliu Island but their operation goes haywire and they get pinned down on the beach until Miller calls in a rocket strike destroying the Japanese machine guns.
They make way for an Allied landing force, in which Sullivan tries to force open a door to get out after hearing a Japanese soldier scream, but Sullivan is mortally wounded when a Japanese officer bursts through the door and impales him through the stomach with a Katana. His assailant is quickly gunned down by Roebuck, Polonsky, and Miller but Sullivan dies soon after. According to Roebuck, the whole squad was stunned and agonized 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", it is revealed that Sullivan's body is being sent back to his family and Roebuck is promoted to Sergeant and takes command of the squad.
- "Grab a rifle. We're going to tear this place apart!"
- "Listen up. I want to get through the rest of this quick and clean! You hear me? Quick, and clean!"
- "Okay, keep it together and we'll get through this in three days!"
- "Fix bayonets, use them if you have to!"
- The Number that appears on Sullivan's dog tags during the cutscene after he dies is "39489987T42P"
- An address on Sullivan's dog tags reads "2812 Harter St. Dayton, Ohio". This is his next of kin's (Mrs J. Sullivan) address, which in turn could be his address.
- In early photos, he appears to be much younger than the final version. This meant that he was going to be in his early 20s or late 10s.
- ↑ In 1944, Roebuck mentioned that members of the "old breed" weren't even thirty. This means that Sullivan was anywhere from 18 to 29, although highly unlikely to be toward the lower end.
