Ima say hell knight, the hell knight is twice the size of the tank and can take alot if hits while you cqn drop a tank with a tac shotty, since its on mars every where alot if thing the tank can throw are small and light wieght due to mars gravity, oh night the tank can breath on mars as long as its in the facilty
Over all tank is dead because if youve played doom 3, theres never a hell knight alone
