Bolos I: Honor of the Regiment

The Mark XV B - M & R

The Resartus Protocol was a final safeguard built in to each Bolo CPU in case of a more general, long term, low profile malfunction.  It was the result of planning and debate fromn the earliest Bolos and A.I.s,  It was NOT an intellectual protocol but an emotional one.  it involved the emotion and quality of "Loyalty".  It determined the character of Bolos.  It was finished and installed with the first batch of MK XV A.I.s. 


A quantum leap in Bolo technology, the Mark XV was the standardbearer of the Concordiat during humanity's greatest wave of interstellar expansion. Very few non-human species encountered during this period could match the Mark XV's capabilities; none could exceed them. This was the first Bolo which did not require an onboard human crewman, due to advances in cybernetics and secure communication links (first short-range subspace com capabilities), which permitted increasingly sophisticated computerized pre-battle planning coupled with unjammable remote human control to correct for unanticipated problems.

Main armament was one 25cm Hellbore with line-of-sight capability, backed by laser cluster "gatling" infinite repeaters (total of fourteen in the Model B) and four 20cm howitzers in individual secondary turrets. The 25cm Hellbore remained incapable of engaging orbital targets from planets with atmosphere due to as yet unresolved attenuation and dissipation problems with the weapons's plasma bolt "packaging," but there were few planetary targets with which it could not deal.

Tactical and theater bombardment capability was roughly equivalent to the Mark XIV's, but the Mark XV had no strategic bombardment capability. The Mark XV's six track systems each had and independent power train, and the vehicle carried both primary and secondary fusion plants. Cybernetics were divided between two totally independent command centers as protection against battle damage, and durachrome was wholly abandoned in favor of a much tougher flintsteel war hull.

Early models of this mark saw the last use of anti-kinetic reactive armor. Major improvements in suspension were required to deal with unparalled battle weights (1,500 tons in the Model B, rising to over 3,000 in the Model M), but road speed held constant at approximately 65 kph (with brief "sprint" capability of over 80 kph) over the life of this Mark, although the "lightweight" Mark XV, Model L, EW platform, at barely 1,100 tons, was 37 percent faster. Cross-country speed was equivalent to road speed except in very rugged terrain. This Mark enjoyed a very long, very stable evolutionary history (mainly because the Concordiat didn't run into anything the Mark XV couldn't handle.
