Tanks are missile targets. The bigger the tank, the bigger the target. This isn’t 1941 anymore. The “Panzer Brigade” has been overcome by missile and remote sensor (drone) technology.
The problem here is that there hasn’t been a proper contemporary-tech, large scale armored war between near-equals since 1973.
There is very little to go on as to what makes sense in such a situation should it happen today. If it can happen today.
