I personally have had a blast, but I'm sure a patch will be on the way to address some balance issues;
1. US M-60 class; ridiculously overpowered. No one uses the regular M-16 troops cuz the M60 just destroys all AND has the LAW which means you can kill tanks.
2. UH-1 gunship 2nd seat machine guns kill MiGs like they are made of paper. My friend and I were doing so well that people refused to fly them in our server cuz we'd shoot em down quick.
3. Mi-8 attack is way too powerful. If there isn't a phantom around, then the US can't stop from being destroyed at will. I went something like 54-3 the other night with it and singlehandedly won the map we were on.. lang valley or something. The US also has the Cobra but the heat seekers are the 2nd gunners secondary fire so its a lot harder to coordinate.
4. personal rifles do jack against aircraft;; which is realistic, but as said above the heli's really can be used quite effectively. my friend brought his machine over and between the two of us, we were unstoppable.
anyway, its really quite fun
