Hint: Righteous Archer
On the last mission called Righteous Archer take out the four towers first. Around the back of the compound (on your map it's the big grey square) there is a helicopter, blow it up with a missile launcher and then continue on with the level. Note: This will not work if you enter the town because he will be alerted and escape.
