Tank Dempsey was a marine raider in the Call of Duty series and is a playable character in the Nazi Zombies game mode. He is only seen in Shi No Numa and Der Riese in Call of Duty: World at War (he' was at Verruckt but this was unconfirmed until Call of Duty: Black Ops), but in Call of Duty: Black Ops appears in all four original zombie maps, as well as Kino Der Toten, Ascension and as an easter egg in Call of The Dead

Dempsey was originally the leader of a small squad of marines whose mission was to recover Peter from the Group 935 station at Verruckt as it was feared Peter's identity had been compromised. It is unknown if his team reached Verruckt before or after the zombie outbreak. Somehow he became one of the subjects of Dr. Maxis' and Dr. Richtofen's experiments with Elelment 115 (Unpentium). He did however experience a complete memory wipe but retained his personality. Richtofen was then ordered to keep them under observation. In Call of the Dead, he and the other three are trapped in a small room.

Now for some random facts:

  • Dempsey likes the monkey bomb
  • He hates the quick revive because of its fishy taste
  • His favourite perk-a-cola is Juggernog
  • He is based on a stereotypical, exaggerated American war hero
  • He hates Dr. Richtofen
  • Dempsey's favourite weapon seems to be the M16
  • He often calls the Wunderwaffe DG-2 the wonder waffle
  • He doesn't like prunes
