Get rid of CMTC for starters. "Laser Tag" may be nice, but it detracts from the training events/lessons that we aim for. As well, 19 tanks sitting there, awaiting serials to show up is a disgusting waste of resources.
The sqn here doesn't have four troops: only three. Assume 19 anyway (spares)
Maybe it's time for a Bde Tank Squadron, and a full up Recce Regiment per brigade group?
So, four squadrons (56), one in each brigade, and one deployed.
That leaves 44 for 'other uses', including a squadron at CTC (if you have none at CTC, then forget about having any in the brigades). Now down to 25.
So, the three armour regiments have say two recce squadrons and a tank squadron. The tank squadron is a brigade asset and the recce squadrons can pair up with each of the infantry battalions as required, or centralised if needed. (Yes, only two infantry battalions per brigade). Coupled with an Artillery Regiment of two gun batteries per brigade, it's smaller than what we have, but it's enough for our deployments, if stewarded properly.
So, in the end, each brigade looks like this:
Bde HQ and Signal Squadron
Armour Regiment (1 tank, 2 recce squadrons)
Artillery Regiment (2 gun batteries)
Engineer Regiment
Service Battalion
Infantry Battalion x 2
Now, assume for a moment that we are deployed "somewhere" in the world where we need a battlegroup. Suppose infantry battlegroup, with tanks and recce.
(I know this is a stretch, but hold on, I'm going somewhere with this)
Assume further that the brigades are numbered 1st, 2nd and 5th (don't ask about 3 and 4: they were bad, just leave it at that!)
So, army commander rings up 2 bde comd and says "I say, Dean my boy, you are next up in the hopper. I'll need an infantry battlegroup with a gun battery, engineer squadron, recce sqn and tank squadron attached OPCOM. As well, I need a Bde HQ, a Service Battalion (*cough* "NSE" *cough*) and an OMLT. The Infantry battlegroup only needs three companies, so that fourth company, they can be the OMLT. The rest of the bde, well, they can assist with your training. You deploy in 6 months and you'll be gone for 9. Questions?"
(Assume again that the infantry battalion has four rifle companies and a skeleton Cbt Sp Coy of recce and sigs).
I don't need an experiment to see if this would work. It's what we used to do, but there are fewer infantry battalions (by four) from say 1990. But instead of people deploying, returning, going on leave, and starting training AGAIN, this time there are six fully functional battalions that can deploy for BG and for OMLT. With tweaking, of course. But a hell of a lot better than what we're doing.
Just my two pence worth...
