3mm models? I've been painting 15mm for a while, and I don't think I could go any smaller. As for FoF, I have recently toyed with it, but decided to go with Bolt Action instead. That's not to say I will not revisit it at some time, as I read a great battle report in Wargames Illustrated recently using FoF rules set in Grozny with Russians fighting Chechyans.
I was able to find a couple battle reports, but nothing involving vehicles. the infantry rules felt a little like Infinity with the double action and the possibility of reacting to the enemy. anything you can say about vehicle rules?
