BOLO MK II

The Mark II was an updated Mark I, with greatly improved onboard computers and the same main armament, but with the first light lateral infinite repeater armament (four railguns in two two-gun batteries). Fitted with gatling and counter-missile point defense. First durachrome armor (10 millimeter) capable of defeating any weapon short of the Bolo's own DSFSLRP round. Electronics were designed to allow a single crewman to assimilate data and operate the entire system, and weight rose to 194 metric tons. The Mark II's fossil fuel power plant drove electric generators rather than powering its drive train directly, and the vehicle had a limited (12-hour) backup power supply of ionic batteries. The Mark II could also operate on electrical power from a secondary source (such as local civilian generator capacity) to maintain long term readiness in the area defense role. Maximum speed was approximately 80 kph (road) and 30 kph (cross country in average terrain). The Mark II was the last Bolo with only two tread systems; all later marks were designed with "wide track" treads-that is, with multiple track systems across the full width of the vehicle to reduce ground pressure to the lowest possible value.
