I think you have been misreading some things, bud.

you said don’t invade Russia or Ukraine in the winter.

I said the mongols did it, and they are the only invaders to conquer both, Russia and Ukraine, so… they have something to teach you. They chose to launch major campaigns in December, because that is the best time to fight wars in that geography otherwise you get trapped by rivers lakes swamps and mud. When they are frozen, you can walk across them… in fact it frequently gets so cold you can drive tanks across them… When you said “lol horse r coldproof” truck r not.” I demonstrated that you are entirely incorrect, and the opposite is true.
