On the civilian/military thing, please, NO! A civilian can train to shoot in a combat situation as well as the military can, please don't make a physical skill out of a cultural/social issue.
Mike, how do you implement coolness under fire in MgT? I don't recall their being a specific rule for it. Personally (yes, I know this isn't in the rules) I use gun combat to include basic small unit tactics, squad or fire team level, not platoon, that'd be a Tactics proper skill. It's handy when your players want to run out of cover with no covering fire to remind them that their basic grasp of tactics says that's a bad idea!
Even the military CAN'T teach coolness under fire. They do some good psychiatric skills training and simulation to a degree. NOBODY knows how they, or anyone else, will react until they are under fire.
I've seen macho jocks cringe and cry like babies and nerds excel. You simply can't predict ahead of time. You train, train, train and see what happens when the time comes. (BTW, some of the bravest men I've ever seen piss their pants in combat.)
I like the idea of troop quality used as a combat modifier. Rightly, or wrongly, I assume veterans have come under fire and are better equipped for it than green troops. (No certainty of that though, but, what can you do in a game?)
