This mission is a bit of a troll, isn't it?
Just to see how unfair it was, I loaded it in the editor, put a Seawolf submarine in the middle of the mission area, and kept my planes on the ground. 700 points. "Average."
Mission accomplished, no casualties. Average. Troll city!
The mission worked a bit more like a game when I set it up differently. I loaded the coastlines with an even dozen Patriot batteries, then walked away for an hour. At that point, it was a nice little puzzle, figuring out how to strike most efficiently, without having to worry about clouds of AAMRAMs from wheels up to shot down.
