Shadow Ops Red Mercury Help

You probably cannot believe this, but I cannot get pass the first level. Its an intense game. Did any of you have the same problem? Any tips.

 

I looked around and could not find a walk-thru of the game. Here are the cheat codes when you get tired of not being able to get to other levels.

Thanks for the help. I already have those cheats. Its a hard game.
