Going to be interesting to watch since The Ukrainians havent been trained in those.
From what I have seen the tactics they used in the past months is pure comical..even on both sides.
They laugh at the smaller tanks that have been used in that conflict but here is a hint. Heavy tanks required sound footing. And taking heavy tanks off road in muddy conditions leaves them as nice big targets.
Ground freezes hard and it helps. But if that ground isnt froze hard enough they will break through the crust and bog down.
Will see.
