BOLO MK VI
The Mark VI was the direct descendant of the Mark III "mobile firebase" concept. It had the same power plant and computer support as the Mark V, but the Mark VI's "main battery" was its missile load, which was configured for maximum flexibility. No railgun main armament was mounted, but the 60mm infinite repeaters were upgrades to seven guns per side, and a heavier point defense battery intended to provide cover to other friendly units and to protect the Bolo itself when operating in counter-battery mode was fitted. One-man crew; 23 tons; speed roughly comparable to the Mark V's.
