In the real world it can be interesting to consider that there were only really two kinds of bunkers. The military ones like Titan Silos or aircraft shelters on base. Who's only basis was to give some key staff and equipment are passable chance of surviving a surprise attack.
And then command and control bunkers, who's sole purpose was just that command and control.
They took information in, processed it and sent instructions back out again.
In the UK the old government HQ bunker just outside of London is now a museum and it's an interesting view point into the thinking of how these things worked. It's pretty big built over 3 levels (so about the size of one of the 15 inner buildings in Cheyenne mountain so 6% the size). It would have had space for up to about 600 staff.
And would have operated like a warship (a submarine most likely no one gets on or off).
This would have meant.
1 Hot bunking and a very small locker for your belongings if you were lucky.
2 Strict rationing on water (about a litre a day and chemical toilets)
3 MREs the only source of food
4 A medical bay as opposed to any sort of hospital.
5 All staff would have been focused on the task of getting information via telex, radio then processing it, then back out again. Or actually maintaining the bunker (mechanics, electricians etc) or being in charge of services in the outside world (e.g. one person being supreme commander for all the police services for millions of citizens).
6 Most military staff would be signal corp communciation engineers. With a very limited role in maintaining order and providing military services so to speak. According to interviews I've read about soldiers on these dutys during these exercises, the arsenal of the bunker would have been a locked case containing 2-4 38 Webley revolvers of WW2 vintage and maybe 100 rounds of pistol ammo.
In theory other troops would be guarding the perimeter around the bunker. Not counting senior officers in the bunker its self etc.
Obviously this is nothing like Prime Base, which was meant to stay open for 5 years. Most bunkers of any size were expected to stay locked down and operating for no more than 3 months.
But it offers some interesting thoughts. The space in a bunker is amongst the most expensive in the world, so it can't be wasted. If you park one v-150 or even a humvee its taking space for maybe a week of week for the residents or bed space for 20.
As such it increases my view that Prime Base was a big white elephant and the actual project may still be slumbering else where.
