It's true about the armor - there wasn't much way to fight it. I don't think they knew about Molotov Cocktails ... As far as small arms: after the Germans put down the Milorg, armed resistance was carried out more and more by Britishicon-trained Norwegianicon commandos. They were provided with Enfields, Sten guns, and assorted other British gear that was smuggled or air-dropped. You can read about it in my cousin's book, "Skis Against the Atom" They lived a tough life between operations, holed up in the high country.
