The only thing is predators aren't designed for CAS missions, not that it can't take two aimed shots, its going to be up there for about 15 hours providing overwatch or intel to the ground troops. From the commanders perspective you'd just about eliminate the fog of war aspect if you had one on station. I'm not sure how you'd add that to the game. The Reaper would actually be a more appropriate addition since it is a CAS platform by nature. You'd get more bang for your buck to, 16 hellfires (eventually) and 2 gbu's. Another option is the MQ-1C (see the army's Warrior for reference), adds another pair of hellfires and has better sensors and should be replacing the B models some day. Of course I'm not sure big airforce has actually sat down and thought about how these will be used in a real war, still a little bit of that "ooo look at the cool remote control plane" mentality out there..... and I think I've rambled enough now.
