Sorry for asking Za but in real life ( in 1941 ) how soon would you expect the other forces to get to Rovaniemi and how many paratroopers would still be alive by then?? The main reason the Germans did not get anywhere ( to Murmansk that is ) in Lapland was the roadless forests etc. Easy to defend both ways. Tanks could not be used. So your paratroopers in Rovaniemi would simply be destroyed there, I think, in real life 1941.
This is what the Forest Lapland looks like and as you can see not good for "blitzkrieg".
