A system for a two-piece armored cab includes an upper cab portion, a lower cab portion, and a vehicle chassis system. The upper cab portion and the lower cab portion are armored to provide protection to occupants of the cab system. The upper cab portion removably mates to the lower cab portion at a mating line that comprises a lower edge of the upper cab portion and an upper edge of the lower cab portion. The lower cab portion is mounted to the vehicle chassis system such that the vehicle chassis system is operable when the upper cab portion is removed from the lower cab portion as well as when the upper cab portion is mated to the lower cab portion.
