Did SU have artic tech during the finnish winter war IRL? Did they develop it before the german attack? Where they any better to begin with or was it their disregard for their own soldiers lives that gave them an advantage?
Their Siberian troops were very skilled, highly trained, winter fighters but were stationed in the far east of Russia to counter the Japanese threat. They were pulled back in late 41 and managed to tip the balance in the battle for moscow.
