Naming conventions aside (I am not sure if naming a sub-unit after a process or a function is a key issue here) one of the most interesting arguments I've seen to date, both on these forums and in the Army Journal, on the Affiliated Battle Group at this point in time is the need to shrink to grow. The goal of fixing the "hollow Army" while at the same time prosecuting a warfighting operation overseas seems to produce conflicting effects on our units (ie: plug'n'play BG's, centralizing core unit functions in order to manage resources, etc, etc).
The notion of "shrinking to grow" is that we are, to paraphrase General Eric Shinseki, fighting a 9 battlegroup war with a 6 battlegroup Army. By organizing, employing, and managing our forces as if we can sustain nine robust Battlegroups, perhaps we are creating unnecessary friction within our operational units (this is as much a question as a statement).
The "shrink to grow" idea has us reduce the regular force infantry establishment to 6 battalions. I would imagine this would entail reducing the 3 Battalions to "zero strength". This is done for two reasons:
1. Our nine battalions struggle to put together full strength rifle companies. This forces them to - as we've seen, from ROTO 1 in Kandahar on, we've had a confusing array of sub-units pasted together to form a fighting unit.
2. Irregardless of "bayonet strength", a battalion requires personnel to fill key administrative and support positions. Requiring these positions be filled for battalions that can barely scrape together two full companies (which can, at times, be "ghost companies" with most pers away on course or supporting the training establishment) puts additional strain on our manning situation.
So, we have six battalions, but we ensure that each one is manned with 4 rifle companies manned to 100% (this is both our doctrinal amount and that required by a "Robust TF" such as Afghanistan). This puts 3 Infantry LtCols and CWOs out of the job, as well as 3 Majors and MWOs as the Infantry has went from (theoretically) 27 rifle companies to 24 full-strength, real ones. Hopefully, there is some additional manpower (PY's) in the cut to allow us to fill out some key functions we've been missing such as Combat Support or sub-unit echelons. As well, the Battalion's Admin company could be filled out, recognizing that it will serve as the foundation for Task Forces deployed abroad.
The Affiliated Battle Group concept gives leads us to the next logical step - since our Task Forces are to be built around Infantry Battalions, I could see the other Branches of a CMBG organized around the principle of shrink to grow. The Artillery and the Engineers - usually the smaller of the Combat Arms units, could form their Regiments around two very robust sub-units and perhaps some niche capabilities that are farmed out as needed. Each of these robust sub-units "affiliates" with one of the remaining battalions. Each Armoured Regiment, with both its recce and armoured (DFS) sub-units, may be forced to create more. It would have its two affiliated "robust" Armoured Recce Squadrons as well as 1 (or hopefully 2, so they could be affiliated as well). There appears to be minimal savings in the Armoured Corps under the "shrink to grow" concept, so perhaps they would need priority on new PYs. Naturally, the Service battalions and Field Ambs would use the same concept to organize, using the concept of "affiliation" and "robust sub-unit" packages to be plugged into deploying Task Forces.
As the institutional "main effort" right now is to fill out the hollow Army, these units would continue to take in new recruits and perhaps man their sub-units to 115% or create additional sub-units as needed. When a critical mass is reached, the excess can be broken off and the 3rd Battalions stood up again, with corresponding increases in the other arms used to create robust "affiliated" sub-units. Until this point, the Army can provide, with minimal shuffling and "Robbing Peter to Pay Paul", 6 full strength Battlegroups to CEFCOM as needed. Managed readiness would dictate that these would deploy once every 3 years (with 6 months at "heightened readiness" as strategic reserve). Whats more, by sucking back to reload, and going for the idea of fewer but better units, these Battlegroups would be more self-sufficient and make less demands to dig deep into the institutional Army to fill out NSE and NCE structures.
Shrinking to grow may seem regressive and antithetical to the governments plans to expand the military, but it may be the best short term solution for long term success.
