Jo6pak, as long as I get credited, it's yours.
KraigWy, the Infantry still walks. A lot. M4's are also easier to hop a fence with.
I always wished that us grunts hit the range more often, the Marines have it right (maybe, I've never been a Marine, can't say for sure). But, I don't trust the terminal ballistics of a 62-grain pill at 500 yards. Great for punching paper, not sure about people, though.
Good equipment will never be a substitute for good training.
