BOLO MK XVI (Retarius)
The increasing size of the Mark XV led to a fresh attempt at specialized design, and the Mark XVI was, in effect, a "light" Mark VX. Main armament remained a 50cm Hellbore, but the infinite repeater batteries were reduced to a total of eight weapons and the howitzer armament was deleted. (As partial compensation, the Mark XVI replaced its laser infinite repeaters with ion-bolt projectors, with much greater ability to penetrate ablative armor, and received a six-gun battery of short-range breech-loading 20cm mortars to augments its anti-personnel clusters.) A complete ablative outer hull was adopted to replace previous appliquies, and cybernetics were equivalent to those of MArk XV/R. Weight fell to 3,600 tons, and road speed rose to 90 kph with short duration "sprints" of up to to kph possible. The Mark XVI formed the "light regiments" od the original Dinochrome Brigade.
