I wish my air was that effective when I use it!

The only way to stop a particular air attack is to actually shoot down the aircraft/helo performing it. This is difficult as MPADS almost never do "shoot down" damage.

The "key" is to damage aircraft/helos so they will not return later to haunt you. If you can limit them to one pass each, while annoying they're generally not devastating.

While it's tempting to use all your SAM/MPADs and try to shoot the suckers down you're better off making sure you have them spread out, firing wise, to cover at least the first half of a scenarios length/turns.
