Changing AI skill

Is there any way to change the AI skill level of the opfor in campaigns? I've just recently started playing this and I'm getting obliterated.

Thanks

I know how you feel. But I have to tell you, I spent some time trying to learn the details of the radar system. After I was able to get a better understanding, the AI opponents became much easier. Human opponents in multiplayer is another story. I feel like an idiot in MP.
