Can NOT complete the mission (sorry, can't remember the name) where you have to keep the terrorists from launching a nuke. It's the one where you're you have to enter Russian airspace unauthorized, the one with all the snowmobiles. There's just too many defenders. I must have tried it 30 times, have tried everything I can think of: approach the hot zone from different angles, take out all Russian air asssets first, sneak in low and slow or zoom in high and fast with everything blazing, fly around taking out every target on the map before approaching the nuke silos (with 4 or 5 trips back to the FARP) -- nothing works! Every time, before I can take out all the nuke sites or even the headquarters building, Dark Star tells me they've launched one and the mission is over. There seems to be just too much firepower defending the silos and not enough time to do it. Anybody got any tips? I hate to sound like a simp but I've really tried hard to beat this one, and no joy! Any input appreciated, thanks.
(p.s. and if I can get past this one there's still the one where you have to stop the convoy carrying the friendly agent though the woods - that's **** near impossible also. Sheesh some of these are hard!)
