I seem to remember that the Home Guard units in Denmark and Norway were about a large platoon in size and were commanded by a Reg F Pl HQ. They trained regularly, including the guy who was OIC Nuclear Demolition Charges for the big bridges who also happened to be a truck driver.
I think they were grouped in companies and battalions regionally, anchored on the key points they were responsible for. They kept their personal weapons and ammo at home. Being fully 'Woke' to the cause of national survival, these were gender balanced fighting units!
Again, a big resource drain - but it makes sense if you're expecting 5 x Soviet Airborne Divisions to drop in for lunch unannounced.
And I know Blairmore really well, my in-laws being from there. The locals are so heavily armed I don't think it would be possible for the CAF to outgun them
