For those of you concerned about deploying the MGS in Canada, or any of the other LAV variants, it takes about 65 hours to drive from Vancouver to Halifax on the Trans-Canada. With the way the LAVs are deployed in Edmonton, Shilo, Petawawa, Valcartier and Gagetown the only major urban areas not accessible by road in 12 hours or less are Whitehorse (23 hours from Edmonton) and Yellowknife (16 hrs). Tuktoyuktuk is about 36 to 48 hours away.
These are the only areas with good road grids where LAVs can operate. (And before the Tankers chime in here, I am going to suggest that without roads to supply gas and spares tanks aren't going to go very far either).
That area accessible by city streets and farm roads is only about 8% of Canada's Land Mass. Something like 20% of the rest of the country is bush with forest cut lines in it - neither very good sight lines, nor very good manoeuver options when restricted to trails ( and before folks start talking about the Ardennes you can drive across that in less than an hour on the highway), nor very good mobility on logging roads. The rest of Canada, something like 70% of it, is totally unserviced by roads. Once your LAV or MGS gets off the runway, where exactly is it going to go?
It isn't inconceivable that there may be uses for LAVs in insurrection situations in the South - though I don't expect to see any such in my life - but that isn't where we are being challenged. We are being challenged in those areas we don't choose to live - up in the North, where there are no roads.
If we don't currently choose to live and work there then come the day that somebody else does so choose then we have little case to argue they should go away. Until we decide that we can either dispose of, trade away or heaven forbid exploit those areas ourselves then the conventional means of staking a claim is to put a fence up, a few sign posts and have a night watchman on the premises. The most probable enemy he/she will encounter in that role is criminals of the claim-jumping, poaching and smuggling variety - sometimes armed, sometimes organized, sometimes supported by foreign interests.
To deal with those threats in those environments helicopters, BVs and boats are more practical than LAVs.
The CH-47F/G can self deploy anywhere in Canada in under 16 hours or so. The Griffon would do better with an air assist like a C-17 or to be locally forward deployed (fixed base or perhaps Ice Breaker?). The BVs and the boats however are both deployable by C130/C27/C295 (sometimes with the tops down). They can also both be lifted short distances by the CH-47s.
MGS may or may not be a good piece of kit. It may or may not be a valid addition to a LAV task force. It may or may not be liftable by the C130. But, domestically, its air deployability is not a major issue. It can get to most areas that it might usefully operate fastest on its own tyres - IF - it is regionally deployed (not the current plan but presumably there is actually little expectation of the MGS firing at live targets in Canada).
Cheers,
