Actually, I agree with Westie when he talks about level of education - to a point.
The average level of education among NCMs in the Reserves is higher... so what? The real indicator here is whether Buddy is capable of performing his/her duties as required on operations, and I have to give the edge to the regs, but only for a short time.
As has been related above, once on the ground, the lines between so-called full and part timers gets very blurry, especially when you consider that there's no such thing as a part-time CF soldier once you land in Bosnia, or Afghanistan, or wherever the next mission is. The only part-time soldiers I heard about over there where the local guys...
Professionalism (as in the ability and desire to do a good job) in the Reserves is very high, and I'll go toe-to-toe with anyone who says different - where we are lacking as an organization is in the maintenance of skills and equipment - let's face it; one garrison evening a week, two weekends a month (field or range), and a couple of weeks in the summer would not allow
anyone to perform at their best on zero notice.
The other issue is, of course, cohesion. If a Reserve unit were to train up for and participate in an operational mission as a body (OK - so it's a dream world, but consider the argument, at least), they would probably perform at least on par with any equivalent body of regs. It's when individuals are tossed in to a section or platoon or HQ that we have issues that happen anywhere an outsider is suddenly introduced to an already existing team. In the cbt arms especially, this kind of disruption is magnified, and in the high-stress environment that is any operational mission (esp. something like Roto 0 in Afghanistan), the slightest friction can be magnified into something beyond belief.
Thankfully, most (unfortunately, not all) soldiers that I have worked with have possessed the common sense, maturity, and professionalism to work through the problems with little more than some good-natured ribbing.
There are and always will be differences between regs and Res... and between Joe A and Jim B (although I prefer the differences between Joe A and Jane B - but that's me

). If you are able to work through them, then maybe you're a better person for it. If you refuse to even try then, IMHO, you're not worth my time.
