Nice summary & agree was being simplistic spliting WW2 MBT & basing on major powers nice summary. I had not realy thought about jets but you are right the era of comparitivly safe overfly was early MBT nice call.
I think its reasonable to say my original comment about the more modern the force the easier it is to react still holds. But it has a flip side applies to the other guy to & as everybody tends to be far more dangerous this adds to it. Infantry are far more dangerous to armour & the reverse applies & as you say once infantry become reliable tank killers combined arms is the way to go.
Dodging arty in early mid WW2 is a huge problem no wonder WW1 was trench warfare
