This whole topic has dominated my interest over the last week. The more re-reading and research I've done, the more interest I have in developing some scenarios myself for this area.
The most interesting aspect I've encountered is the defense philosophy both of the Norwegians, but also the reinforcing NATO forces. Take a look at the following source I just found yesterday:
http://www.dtic.mil/dtic/tr/fulltext/u2/a224142.pdf
"Who will stand the Nordic Guard?"
It's hard to read because it's a pdf of a type written report, but it gives a good history of the Norwegian and NATO defense strategy, as well as opposing force theory. I know it's again later than what you want in your era, but its helpful.
What I like about this theater is the use of indigenous Norwegian forces (deployed in Finnmark and in Tromms, homeguard, and reserves), as well as bringing in reinforcements from the USMC, British Marines, Canadian CAST Brigade, and Dutch Marines. The terrain is terrible for the attacker, but quite Spartan in concept for the defender.
You've even got me working on maps to use. I started one for Bardufoss, and just got topo sheets for Narvik. They'll take me some time to workup, but I'll try to share them when I'm finished.
Thanks Suhiir! My wife's about ready to "deport" me!!
