The Norwegian defence was hinged on the 'Lyngen Position' - where they established a strong blocking defence and deployed the bulk of their forces in the North (incl. Brig N ('Brigade North')there.
The Lyngen fjord is a narrow passage where basically the mountains meet the ocean - and it located west of the so called 'Finnish wedge'. The Norwegians did not expect to be able to stop a Soviet advance east of the Lyngen position, and figured defences in the border region with the USSR were vulnerable from being outflanded by Soviet forces moving through Finland ("The Finnish Wedge").
The terrain in the arctic and the poorly developed infrastructure is limiting for military land operations - much of Norway is also mountanious.

East of the defences at Lyngen, in the Finnmark region, Norwegian defences were not particulary strong - numbering about 5000 or so in various smaller units - dedicated to delaying actions.
IIRC the Norwegians were concerned about the Soviets using seaborne forces in a simliar fasihon as the Germans had done in 1940 to land forces along the Norwegain coast at multiple locations.
Some Swedish officers expected that the strength of the Norwegian defences at Lyngen would prompt a Soviet invasion of Finland and Sweden in order to outflank it.
Here's a list of Soviet forces belonging to TVD Northwest:
(note: it's not complete, and of uncertain origin (found it on a Swedish language forum) but gives a pointer to what Soviet units were located there. I imagine it's from the late 1980s, early 1990s).

Some Soviet units were organised according to the Mot Rifle Div NORTH setup - which had somewhat less strength than the ordinare MRDs but were probably better equipped to operate in the arctic region.
