One would have thought that the Germans would have remembered that they needed cold weather gear from mid-October on while on the Eastern Front.
Ask the public for spare furs. That’s what they did back in the ‘40s!
I bet the temperatures encountered are far worse than those quoted. The only way around it would be a fully shrouded insulated/heated unit, increasing battery weight and energy consumption.
My first thought exactly.
My second thought was, no, that's not possible, as either General Winter or the Russians killed just about all of those with first-hand experience.
