Russia has deployed, we think, between 12 hundred and two thousand tanks. But it means that the ukranians have two western missiles or more a for evry russian tank. Plus they have their own anti tank weapons, even simple, simple ones like r p gs. So there is a saturation of these weapons on the various battlefields which means that i think the era of the tank is coming to an end.
