I was thinking a group to a brigade with defence of Canada role. That obviously needs a further breakdown but in my rough guestimate I would make a group as large as a brigade with some 5,000 + Rangers per each of 4 brigades. That may not be enough for the infrastructure security that I would give them as their ultimate role.
I like that better.
Consider Canada with 40,000,000 people. We are all itemized in any event. We all have SINs. We all show up on censuses. We all show up on voters' rolls.
Take those 40,000,000 and divide them into 200 communities, each with its own community sportshalle open to all. A place where people congregate a get to rub along together.
40,000,000 / 200 = 200,000 people
Now the Danes produce 85 volunteers per 10,000. These are just names. Not active participants, just names.
1700 volunteers
22 per 10,000 are considered active and reliable
440 active volunteers
Of those two thirds are suitable to assist in security tasks and civil emergencies.
Call it 300 in a security reserve
These turn out in emergencies.
The other third is sufficiently engaged as to be able to provide a local QRF adequately versed in platoon tactics to actively secure local facilities and defend against an armed force.
150 in a QRF Company
These have their heads in the game 24/7.
In addition 20% of those are in a mobile patrols element.
30 in a local vehicular patrol troop.
And finally 3 or 4 are keen enough to work with the SOF community.
These take on international assignments.
This force is equipped with cast off small arms from the professional forces.
By and large they train themselves under supervision.
....
And all this is in addition to the 40 per 10,000 in the professional forces
800 professionals recruited from each community and serving full time
And in addition to 20 to 25 police per 10,000
400 to 500 police in each community.
