Adopt US 14x Coy for the tank squadron. Don't have an IFV, uparmoured Stryker with a handy chain gun. Fight them as such. Add Javelins in all right spots for 2 SBCT Cavalry troops (LRSS mounted) and a Stryker battalion. Use the two now surplus Btn sets of LAV's to convert enough for 10 1129's per LAV battalion and 4 per Armoured regiment, 3 1134's per LAV battalion. Upgunned and uparmoured Battalion and Cavalry Squadron from an SBCT.
Filling out a brigade with allied troops is a stretch, but is that non an upgrade on the battlegroup side of things?
Yeah light CAV was a poor choice of words. Weapons carriers for crew served weapons that can either be attached to a larger force or used as road mobile skirmishers. And as I said, TAPV wouldn't be my choice. But given Canada's location relative to any fight it's going to be in, an easily deployable light but mobile force equipped to bring a disproportionate amount of effect (ATGM's/UAVs/SHORAD) seems more attainable than doing heavy well, and more effective than paying lipservice to going heavy, so start moving that way now, optimize later.
Heavy well- not happening any time soon
Medium well- fill gaps for 2x SBCT with Leo's and chain guns, one light Bde equipped as needed (obvious solution, boring to talk about)
