I do have the FFT rules as PDF. They appear a bit too granualr to me, but maybe I just have to extract the elements I need and streamline them a bit as well. Are James and Mike using them at the CGSC? I could hit them up to take a look at their version.
Mordern Armor doesn't really fit my scale.
Did also take a look at Cold War Commander, which, with some tweaks, could indeed be an option. I've seen some reviews pointing out that the first edition is somewhat better than the second, btw, but I haven't compared them myself. Let me know when you play it, I might join or at least watch, in case you are streaming.
