I'm ashamed to admit it, but I'm about to give up on this game because it's too hard for me, even on the relaxed setting. I've gotten as far as scenario 11, where the 82nd Airborne is trying to destroy SAM sites. As soon as the enemy helicopter shows up, it just runs around and blasts things without my being able to respond. I've got the air defense vehicles, but it stays just out of range of those, as it sweeps it to hit everything else. I've tried many things, but now I'm just getting too angry with the game to play it further.
