After reading this entire thread, I felt I had to add a new perspective in to it.
As an NCM with 6 years in the reserves, I may not have the full expertise on everything, but I can at least add the common soldier's perspective to it. It was mentioned the need for armoured vehicles (LAV III, Bison, Coyote), but we have to keep in mind that the modern battlefield is not on wide open plains like it used to be. If we are ever deployed on any major operation, we will be deployed in mostly built up areas. Then there's the mountainous areas that we are already deployed to (Afghanistan). A larger, more armoured vehicle is nice when it comes to anti-recce and suvivability roles, but have you tried to do a turnaround drill in a Coyote on a one-way street or a logging road on the side of a mountain. Having done it in just a MILCOTS, it's extremely hard, and usually time consuming, something we generally don't have.
I still agree on the Coyote as an overwatch vehicle though, it definately fits.
As for the situation with having a large amount of Sgts in a troop, yes, it looks good on paper, but then you look at the reality of the state of the reserve force right now. My unit is just finishing up a house run DP2 recce creman course next week for CPL and below. The initial load was somewhere around 40, but due to the reality of the reserves, people could not commit to every weekend, every parade night, for several months due to real life situations (work, family). As a result, we'll be lucky if 20 pass the full course. Having just seen the LFWA course brick for this summer, there is only 48 spots open for the DP2 recce course. With 6 armoured Recce Regiments in the west, that's only another 8 potential qualified soldiers per unit. By that math, there will be 28 fully qualified NCMs in my unit alone. I know that right now is a transition point, but the situation is dire. Of those 28 we'll be lucky if 5 make it to a CC level in the next 2 years. I'm sure the situation is much the same at most of the recce regiments in the midst of the transition. The recce regiments that were already recce regiments probably aren't as bad off, but the situation still exits.
