We have reached a generational shift where there is a lot of money in the system. So much so, that many of us that have been in for a while can't really wrap our head around it. We have been cultured to do with less and do without for so long that it is our default. We need to open our eyes and realize that isn't the case anymore.
Keeping Reserve units (and Reg force units on some bases) in shitty falling apart buildings that are not fit for purpose isn't acceptable. We did so for so long because we did not have a choice. Now that we do have a choice why constrain ourselves? We will be stuck with ever solution we push for the next 50 plus years. Instead of "upgrading" old armouries or trying to shoe horn units into converted civilian buildings and accepting the compromises that existing infrastructure would force on us, would it not make more sense to design and build what we need? Not just what we need now, but what we think we will need for the next generation of soldier.
It is super expensive to retrofit crypto vaults and CSNI into buildings that aren't designed to have them. Both are going to be necessary. There are a lot of dumb reasons that the Res Force doesn't have dismounted radios, the Army has failed you. One of those reasons is you can't store them properly. When the mounted radios get replaced, you will have the same problem. If we build you new buildings we can put all the necessary stuff in them from day one, it is a lot cheaper to add those things to the design rather than try to retrofit them later.
What we should be doing is designing a standard armoury. What does every unit need (classrooms/weapons vault/OR/storage cages/mess/etc)? Pay to design that building once (or at least design it with "building blocks" so it can scale from one unit to multiple units). Then have the other half of the building specialized for the unit type (Armoured units get a giant room with power/networks for vehicle sims/Infantry get a premade kill house/Svc Bn get a big tool crib and floor space with over head cranes/etc). The amount of money we would save on engineering studies to retrofit a bunch of old, crumbling, buildings would not pay for itself but would go a long way.
