What the hell are Carnation tracks?
EDIT** Disregard, I just figured out you’re talking about the Soviet SPGs.
And regarding your comments on the rules, that infantry and arty are not the battle winners, I don’t think they are/would have been on the Cold War mechanized battlefield. I think tanks were/would have been the arm of decision; sure arty can cause casualties, but in the overall scheme of things it was breaking up formations and/or pinning formations in place so that armored/mechanized elements could outmaneuver them and leave them to whither on the vine. Same goes for infantry, certainly infantry that couldn’t keep up with the tanks. For all the talk of ‘having to dig them out of the built up areas,’ if you’re doing maneuver warfare correctly you’re by-passing the built up areas.
