I don't know the answers but I posted some links at FR
Yeah, I saw that, but the problem is that of perception.
One can read that one tank was 52 tons, and another tank "only" 26 tons, but that doesn't mean excresence to the average person, who understands only that one tank is twice the size of the other.
One is looking for a human, not a statistical, version of such weapons.
This is why the question about the British Centurion tank, the only tank I've ever seen in real life in "action;" something with which one can compare other tanks.
