With respect Mark "It" is a problem.
(1. )Prior to the Grizzly we had a General Purpose Infantry based on battalions of 4 rifle companies of large sections and a company of long service specialists who could be relied on to perform their specialist tasks in support of the rifles, or, when the need arose, could revert to being rifles. One man in each section was lost to the vehicle as a driver. In the absence of the vehicle that driver would revert to life as a rifleman.
In the 80s the infantry wanted a piece of the armoured battlefield. Our enemies and allies were all kitting up with BMPs, BMDs and Marders. The Yanks were working on the Bradley and the Brits on the Warrior. Canada's Army, and the Infantry in particular, wanted to stay "relevant" to that fight. The government of the day was less enthused. It didn't want to further engage in Europe. It saw the army's role as an anti-insurrection force with domestic application. And it didn't want to risk "tanks in the streets" and to civilians an IFV, with its tracks and turret, is a tank.
Consequently the government authorized the purchase of the AVGP. A brilliant police vehicle for something like the para-military police of Europe. At odds with the British traditions of both a non-standing army and civil policing.
The Army tried to make the best of a bad situation and employ the Grizzly, and the Cougar.
The Cougar was at least given the accurate description of being a "trainer" - even if it was a poor tank trainer.
The Grizzly should have been designated as an IFV trainer for Panzergrenadiers.
The problem was that the adoption of the Grizzly forced the conversion of the General Purpose Infantry sections to specialist Panzergrenadier sections. Sections that dedicate 3 of their number to crewing their vehicle and only allow for 6 dismounts for General Duties. And those dismounts are specialists in the Armoured Battle, tied to their vehicles and equipped for that battle. But in Canada's case their vehicle was never adequate for that battle and the troops were never given the weapons necessary for that battlefield - namely the section level, 2000 m, Milan ATGM.
So we lost 2/3 of the infantry to the specialist Panzergrenadier role while denying them the tools necessary to do that job, both vehicles and weapons (in addition to the lack of the Milan the 20mm cannon was replaced by the venerable, supposedly dismountable, 50.) The other 1/3 of the infantry was actually still in General Purpose configuration with large sections but they were equipped with the M113s which could actually keep up with the tanks while the Grizzlygrenadiers were in the rear with the gear. And the Airborne was in its own special place.
Since that time, IMO, Canada has been trying to catch up.
(2) Coyote moved closer to the Marder ideal with its 25mm turret.
LAV 3 upped the armour
LAV 6 upped the armour again.
We are approaching the capabilities of the original 1980s vintage Marder with better comms - which the current generation of allied vehicles also have.
We still have not completed the transition to the Marder (now exemplified by the CV90) in that we still rely on wheels and not tracks. And we never got round to supplying those essentials for infantry on the armoured battlefield, the anti-tank missile.
Panzergrenadiers are dedicated anti-tank teams that can revert to riflemen when the need permits. But the crew is still lost to the section and is only available to the section if the vehicle can stay in range of the riflemen.
(3) Canada has, again IMO, converted itself into a Panzer Army, without Anti-Tank weapons and a vehicle that struggles to keep up with the tanks, just in time for the rest of the world to move away from reliance on tanks and back to an emphasis on General Purpose Infantry. That is how I see Airborne, Heliborne, Mountain, Light, Stryker, Piranha, Boxer and Scorpion equipped infantry. All of which are equipped with 2-5 km dismountable Anti-Tank missiles, man-portable artillery like the CG 84mm, and are adopting more UAS type munitions in the 40mm to 120mm calibre range.
(4)The good news is that the battlefield is now moving back to asphalt so the LAV's wheels are less problematic. They can cross a short European field on the way to the next road without getting too far out of range of the nearest tow truck.
(5) The bad news is that while our allies are building vehicles that transport full sized general purpose sections, sections that can operate in a variety of environments, with or without their vehicles, vehicles that have separate crews that don't detract from the section, we are stuck with 2/3s (3/3s) of our infantry tied to their vehicles. And we have lost the GP infantry.
(6) Unless we want to consider the time it takes to rerole and requalify a LAV battalion for duties without their vehicles, their turrets, their optics and their cannons. Not to mention without pioneers, mortars, MANPADS and, of course ATGMs.
LAV infantry is a form of specialist infantry - previously exemplified by the Panzergrenadier.
(7) The reason we have so much trouble identifying the role of the Light Infantry is that they are the odd-job men. They are the general duties, general purpose, bog-standard, infantry. They used to be the basis of Canada's Army. Which resulted in an Army which could successfully turn its hand to any problem.
Up thread I proposed 3x DS Brigades (Divisional Support or "Deep Strike", whatever). Those brigades incorporated one specialist infantry battalion each. I also proposed a separate, stand alone, "Light" brigade of 3 "Light" infantry battalions.
I am going to revise that prescription to 3x DSBs as configured and add a second pure infantry brigade. And remove the label "Light" from the lexicon. They are simply "Infantry Brigades". Just like the Infantry Brigades of the Militia. All specialists on working on their feet, to close with and destroy, regardless of season or terrain, or transport.
The number of bodies in the infantry, in a battalion, in a company, in a section doesn't really bother me. So long as they are appropriately organized and equipped to defeat the threats that face Canada at home and its citizens and interests overseas.
And I don't believe that the LAV army does that.
