I've seen the future...
Well good for them, they’re wrong.
This is not a different cultural attitude, this is the delusion of a fallen empire that still thinks it’s the top dog in its neck of the words. Russia is fighting like it’s still the USSR or even the Old Empire; but it isn’t.
Russia simply does not have the resources to wage war on that scale anymore, and by trying to do so they have damned themselves. The only thing that has kept them going so far is their massive stockpile of Soviet kit that they are burning through at an industrial rate. Economic sanctions and their own corruption has crippled their manufacturing to such an extent that the losses cannot be replaced. Their only hope is that Ukraine folds before they finish burning through their stockpile. Because if Kyiv has not fallen by the time the last T-55 is destroyed…oh dear…
They may still, reputedly have some stocks of T-34/85's and IS series tanks. The Soviets/Russians never really threw anything away. Although, if you have to be desperate enough to pull those out...?
