Wow!
Thanks for the info, that's really something!
Concrete armour makes sense, actually I recall now granite being once tested for MBT armor in some countries.
Only bear in mind the fact that police officers were in several cases able to climb on top of the dozer while it was running. Is that the kind of mobility you expect from a tank?

There is something to be recalled from this story though. There could probably be ways to design efficient homemade battlefield armor, like by pouring rubber or reinforced glass between hardened steel sheets, cutting the result and mounting it at high angles (in several layers?) on the sides of a turret. That would give you a makeshift equivalent of the KWS2 frontal armor of the Leo2A5.
