I know I've reffered to WW2 a bit but IIRC after the Nazis Blitzkrieg during the summer of 1941 and before the winter really set in (Which was really harsh and because the Germans had no winter clothing etc) there is that time when it seems roads etc turn into mud baths, plenty of photos/films showing the Germans struggling to make headway in it, I do wonder if this is still relevant or are the roads/tracks much better than they were back then?Sounds about right to me. Winter snows will make large scale operations difficult but not necessarily impossible. If the ground freezes solid that will be less of a problem than a mud bath.
Both sides will spend the winter bombarding each other but will have logistical challenges with regards things like getting shells to artillery pieces. I would not be surprised if some of the training we are currently providing includes courses on how to fight in freezing conditions; it is something we practice ourselves with an eye on reinforcing Norway if ever needs be.
