We don't disagree in principle at all. Here's how I view a 30/70 hybrid battalion:
View attachment 90689
The battalion is commanded by a RegF LCol who has a significant RegF staff. It initially has one fully equipped RegF coy. Each of four ResF battalions are reduced in strength to a full 10/90 company commanded by a ResF major with a RegF 2i/c and a staff of about 10 RegF pers in key positions. The CS company is a 30/70 company so that each platoon (Mortar, ATGM, UAV, Pioneer, Recce) has a section of full-time pers. Training and recruiting is directed and supervised by the bn and executed by the companies. Each company retains its distinct identity (Hell, give the bn an honourary col and go so far as giving each of them an honourary LCol)
The operational roles are as follows:
1) on a routine peacetime basis, provide a bn HQ, one full rifle company and a portion of a CS company which can be augmented by other RegF resources or ResF resources as appropriate for the mission;
2) in the event of an emergency requiring an enhancement of the CA, mobilize the entire battalion by placing the ResF elements on active service; and
3) in the event of a major war, be available to divide the battalion into five "cores" (a brigade HQ and four battalion ones), recruit from the population and train a full infantry brigade with three battalions and a depot battalion in reserve.
Similar structures exist for armour signals, engineer, artillery and CSS units.
In the early stages of transformation, the battalion shares the equipment held by the RegF company. The ultimate plan is to provide an enduring structure for the CA so that all units and subunits will be fully equipped.
What is key here is that the RegF CO of the bn is responsible, accountable and enabled to lead and administer the entire battalion (RegF and ResF) from recruiting through training to deployment. I tend to see these battalions located in urban centres with sub-units generally within the same facilities or within an hour's travel of its hq. To better enable this we should seriously consider separate restricted terms of service for a class of the RegF so that such a RegF soldier has the ability decline postings and promotions so as to spend an entire career in one geographic location. (I would essentially eliminate Class B service for this restricted RegF service who would be fully deployable like unrestricted RegF personnel.)
As I said above, creating a viable and sustainable CA requires significantly more complex changes to the way the CF does business. The good news is that the raw material is there. The army just needs to shed some old BAOR ways of thinking.
