I'll agree that there are a bunch of good building blocks to work with and that a number of the capability gaps in terms of equipment are already been looked at, or in light of what's happening in Ukraine are likely to be addressed in the near future.
My take is that while the LAV may have shortcomings in comparison to tracked IFVs with integral AT weapons, we are not likely to see them being dropped any time soon as our primary vehicle. Too much money in tight economic times and too many other major defence purchases already in the pipeline (NORAD upgrades, CSCs, F-35's, etc.).
Secondly, while I agree that we need to maintain a "heavy" capability for both military and political purposes, I think that realistically a direct military conflict between Russia and NATO in the near to medium term is low. Russia is too busy in Ukraine and has been too weakened to contemplate directly taking on NATO in Poland/the Baltic States any time soon and NATO won't risk initiating a conflict with Russia both for lack of political will and for fear of nuclear retaliation/escalation by Russia if they fear they risk losing. Any conflict/deterrence requirements will likely be along the peripheries where NATO's heavy forces are not already concentrated. This could include along the Northern NATO flank (including the Arctic) where reduction in ice cover will make competition for valuable resources and trade routes much more viable.
Lastly, during periods of great power competition there is likely to be quite a few brushfire and proxy wars as each of the competing powers vies for greater influence and control of strategic terrain and resources around the world. Our LAV-based forces are well equipped to provide support for our allies in these types of conflicts.
My proposal would be to maintain enough LAV-based mechanized forces to be able to maintain our eFP Latvia deterrence force, sustain a Battle Group sized deployment to foreign stability operations as they come up and be able to force generate (and sustain) a Mechanized Brigade Group for an allied Division in case of a major conflict (NATO's Multinational Division - North or an American/British/Commonwealth Division). That force could look something like this:
- Lord Strathconas Horse (Tank) - Edmonton
- Reserve Armoured Regiment (Tank) - Western Canada
- 12e Regiment Blinde Canada (Cavalry) - Valcartier
- Reserve Armoured Regiment (Cavalry) - Quebec
- 1 PPCLI (LAV Infantry) - Edmonton
- 2 PPCLI (LAV Infantry) - Edmonton
- Reserve Infantry Battalion (LAV Infantry) - Western Canada
- 1 R22eR (LAV Infantry) - Valcartier
- 2 R22eR (LAV Infantry) - Valcartier
- Reserve Infantry Battalion (LAV Infantry) - Quebec
- 1 RCHA (SPG Artillery) - Shilo
- Reserve Artillery Regiment (SPG) - Western Canada
- 5e RALC (SHORAD) - Valcartier
- Reserve Artillery Regiment (SHORAD) - Quebec
- 1 CER - Edmonton
- 5 CER - Valcartier
- 1 Service Battalion - Edmonton
- 5 Service Battalion - Valcartier
I'd also have a Light (Arctic/Air Mobile) Brigade both for defence of the Canadian Arctic and for use as a Rapid Reaction Force for deployment worldwide in times of Crisis. This Brigade could be tasked to become the 3rd maneuver Brigade in the US Army's 11th Airborne Division in Alaska as part of an Allied defence of North America force or if required in a major conflict be used as the core to expand to a full Light Infantry Division with integration with Reserve units. This force could look something like this:
- Royal Canadian Dragoons (Cavalry) - Petawawa
- 1 RCR (Light Infantry) - Petawawa
- 2 RCR (Light Infantry) - Gagetown
- 3 RCR (Light Infantry) - Petawawa
- 2 RCHA (M777 Artillery) - Petawawa
- 2 CER - Petawawa
- 2 Service Battalion - Petawawa
- Reserve Light Infantry Brigade (East)
- 3 R22eR (Light Infantry) - Quebec
- Reserve Infantry Battalion (Light Infantry) - Atlantic Canada
- Reserve Infantry Battalion (Light Infantry) - Quebec
- Reserve Armoured Regiment (Cavalry) - Atlantic Canada
- Reserve Artillery Regiment (Towed/Light Wheeled Howitzer) - Atlantic Canada
- Reserve Combat Engineer Regiment - Atlantic Canada/Quebec
- Reserve Service Battalion - Atlantic Canada/Quebec
- Reseve Infantry Battalion (Central)
- 3 PPCLI (Light Infantry) - Shilo
- Reserve Infantry Battalion (Light Infantry) - Ontario
- Reserve Infantry Battalion (Light Infantry) - Ontario
- Reserve Armoured Regiment (Cavalry) - Ontario
- Reserve Artillery Regiment (Towed/Light Wheeled Howitzer) - Ontario
- Reserve Combat Engineer Regiment - Ontario
- Reserve Service Battalion - Ontario
Total Reserve Requirements (by Region) to fill out this force would be:
- Atlantic Canada
- 1 x Light Infantry Battalion
- 1 x Cavalry Regiment
- 1 x Artillery Regiment
- 1/2 x Combat Engineer Regiment
- 1/2 x Service Battalion
- Quebec
- 1 x Cavalry Regiment
- 1 x LAV Infantry Battalion
- 1 x Light Infantry Battalion
- 1 x SHORAD Battalion
- 1/2 x Combat Engineer Regiment
- 1/2 x Service Battalion
- Ontario
- 2 x Light Infantry Battalions
- 1 x Cavalry Regiment
- 1 x Artillery Regiment
- 1 x Combat Engineer Regiment
- 1 x Service Battalion
- Western Canada
- 1 x Tank Regiment
- 1 x LAV Infantry Battalion
- 1 x Artillery Regiment
Any remaining Reserve Regiments that are not required to fill out the above requirements would be used to augment 6 CSSB capabilities or to generate Divisional-level forces for the Light Division (SHORAD and MRAD, HIMARS, etc.).
