What sort of capacity would you need to make this work?
That really depends on the army that you want to have. I'm of the mind that your plan must call for an "army for today" and an "army for tomorrow."
The army for today is structured just large enough to meet your day to day peacetime operational needs and to allow for the development of the NCM and officer leadership that you need to be able to continuously properly lead the army for today and also to be able to form the leadership core of the army for tomorrow. A point here. You may not need special forces today nor an air defence arm but you can predict that you will need both if there is ever a war so you have to have both a school system and a unit or two of special forces and air defence where both those branches develop and maintain the appropriate doctrine for the future and to allow for them to exercise and hone their skills all the way up to the appropriate rank level. Again, your schools will need to be big enough and offer all the requisite courses to allow that career development to happen.
The army for tomorrow is a very different beast. The army for today is develops on a near horizon and the operational missions it is to fulfill are more discretionary in nature and therefore capable of failing without threatening the country. The army for tomorrow OTOH needs to be one built for a vague future which presumes threats to the country's very existence. I presumes that you will go to war at some point. It has several components. The first is an element that can reinforce the army for today on occasions where a small temporary surge in peacetime is needed. The second is a force in being, manned and equipped but in a part-time status so as to save costs and at various states of tiered readiness depending on the threat level. One of its main purposes is to serve as a deterrent to possible adversaries in order to prevent a war but, if required, can be. The third is a core around which national mobilization can occur in the event of a prolonged and major conflict. It has to be able to build an as yet undefined mass from both the civilian population and defence industries. It requires a plan for the populations mobilization and training as well as an existing manufacturing base that can be mobilized.
While the army for today is relatively small and can benefit from the efficiencies that centralized school and training facilities can provide, the army for tomorrow has a different need. Being a reserve force, it is distributed across the country more than the army for today is. Facilities need to be decentralized to local areas where the troops live their civilian lives. As well, army for tomorrow's larger size would overwhelm a centralized system's infrastructure. This again calls for decentralization. Lastly unlike the schools for the army for today which can, to a large extent, operate year round, those for the army for tomorrow, being targeted on citizen soldiers, must in large part work at volume during the restricted summer months and at much lower volumes at other times of the year albeit for national mobilization it will become a year-round affair.
As such, from the very start, it should be a system that is decentralized and capable of decentralizing even more if necessary. In addition it needs to have a teaching staff which for much of the year does other things. While in part, young reserve force NCMs can be found to teach lower level NCM courses, the senior reserve force staff needed to teach more advanced NCM and officer courses is rarely available. That presupposes a need for a large influx of more senior RegF NCMs and officers.
So, to get back to the capacity question, which is one of political decision, my response to it is to build a force structure based on hybrid units, like this:
Within each hybrid unit is a RegF component of a headquarters and at least one fully manned RegF subunit (and perhaps elements of a combat support company) The purpose of the headquarters and the company is to provide army for today elements on rotational tasks and to be a battlegroup building block core as many of the Afghanistan rotations were. Over and above peacetime operational deployments, these cores provide a career development structure for their RegF personnel and the foundation to which 2 or 3 ARes companies are attached. Sept to April the RegF core trains itself, May to Aug the core takes leave, APS and provides individual AND collective training to the reserves.
The hybrid unit is designed:
- firstly to provide individual augmentees from its ARes personnel to its RegF coy or to other deploying units;
- secondly to provide force expansion as a fully deployable unit; and
- thirdly, in the event of national mobilization, a hybrid unit may be reformed into a brigade where 1/4 to 1/3 of the force is made up of the RegF and ARes personnel from the unit and the remaining 2/3 to 3/4 of newly enrolled recruits who are trained and led entirely from within the brigade
Voila. My long-worded answer to your short question.
