It looks like a sudden strike mission will be necessary to take out four facilities. They are of course being protected by a massive defense of AAA and SAM units and think they are safe. Intel has found a back door. You'll never make it to the target site if you try to fly straight in the front. So you must stay under radar as much as possible and get into the hen house through the only opening, like a fox.
Once into the target area, you will use rockets on low altitude runs, weaving around the mountains. The mission is a success when you destroy the four factories, defend against bandits, and get back to the Stennis. You will be assisted by four other aircraft. Base command will keep you updated along the way. An intermediate skill player may be successful 8 of 10 times.
