These vehicles certainly look interesting and I am not saying that they do not have a purpose. I do beleive, however, that at times we want a system because it looks cool but without first having determined a requirement.
Or simply hopping on the US Transformation bandwagon without putting any critical thought into certain initiatives within that process and how (and if) they are actually feasible....
What is the MGS being designed for? The US Stryker Brigades are essentially Infantry formations that add a "motorized" element to the equation. The Stryker Infantry carriers shouldn't be compared to our LAVIII due to the fact that they have a crew-served weapon on a RWS whereas our vehicle has a stabilized turret with a fairly respectable cannon on it.
The MGS is meant to be a company-level support gun for the Strykers. This is an infantry gun; essentially like a StuG of WWII fame, meant to accompany dismounted Infantry on the attack (or back them on the defence, I guess).
However, one has to wonder what sort of roles this thing will fill based upon its specs. The LAV units were kept as cordon forces at Fallujah for a reason - you won't see an MGS replacing an M1A1 in an dismounted, urban assault. So accompanying the Infantry in complex terrain (where our fights will most likely be) seems to be out. So, what use does it have then? It could advance
behind the Infantry in a complex battle scenario; but this puts your infantry in the "trolling" role, and human tissue isn't as good as Chobham armour in taking fire - so I'm willing to say that this is bad on both the tactical and the moral level (see the Aussie Army Chief's statement). Perhaps it can be used to backstop dismounted Infantry on other tasks - cordons and searches, VCPs, patrols, etc, etc. But one has to wonder if a 105mm MGS will offer us anything substantial over the current LAVIII capability? I could see an MGS being valuable when all you have is a .50 cal RWS, but our mechanized forces have much more than that. I'm not confusing the capabilities of a 105mm gun and a 25mm cannon, but in these above roles, it seems that a 25mm cannon in a good turret should be enough for, say, cement mixers charging a VCP, ambush fire from a brick building on the road, etc, etc. If heavier firepower is required, we have other means at our disposal like the new 155mm Excalibur round from our Gunner brethren or we have to consider that perhaps it is out of the league of a Light, wheeled force - giving Cavalry a longer, heavier lance does nothing to change the fact that you can shoot the horse out from underneath the guy.
So my question (and challenge) to the MGS crowd - the MGS is being adopted due to the fact that we've simply ripped some pages out of US Army transformation planning. It seems that it was never considered if this planning even applied to our current organization and layout. Does the difference between Stryker Carrier/Stryker MGS really apply to our LAVIII equipped forces - perhaps some people with more working knowledge of weapons systems can fill the argument out better.
To me, it seems that a DFS requirement of heavier, sustained fire from a stabilized turret with good sensory/targeting capability has already been largely filled out and that the we will not gain anything substantive from a 105mm MGS - there will be no "bang for the buck" on this one. If we want maneuverable armoured capability that provides tactical mobility and heavy firepower, then we are foolish not to buy a modern MBT like the M1A1 Abrams, as this requirement is heavily dependent on protection that a LAV chassis can simply not provide.
If we wanted to add a real addition of capability to a LAV organization, I'd argue for the LAV-based 120mm gun that I discussed before - new 120mm rounds can be used as pretty potent low-velocity DFS while a 120mm indirect-fire capability for a sub-unit seems to be a pretty nice additional capability.
