Hannibal Mantis. "Hannibal works closely with the UNSC in its efforts to incorporate new weapons technology on existing vehicle chassis. Advanced Mantis with heavy armor, rapid-fire gauss cannon, and experimental ion field missile warheads.". I swear this is the rarest REQ in the game, I never get any of these hence why the showcase took so long. Such an awesome vehicle though, definitely my favourite Mantis :).
