Here you are, bud. I had the same thoughts a good while back and got stuck into the long chore of creating not only SAM sites, but Flak batteries as well for both sides on the map. I decided to make Kurzah, the capital of Paran, something similar to downtown Hanoi; with four SAM sites and twelve Flak batteries scattered within and around the immediate vicinity of the city, so if seeing those big smoke puffs during a strike mission is your thing, then you won't be disappointed. My advice is to try out a strike mission in Kurzah and if your framerate goes a little too low, then delete a couple of the Flak batteries of your choice.

I probably don't have to tell you; but just in case, just copy all the text in the attached file, paste it on to the end of your DESERT_TARGETS.ini file and change the 'TargetArea' numbers to correspond with the rest on that file.
Here's hoping you have some good ducking and diving!
