This is definitely in the top three hardest spec ops missions. There are many ways to do this mission but this way is one of the easiest. The order of the buildings is important. We saved the one on the left for last b/c it was closest to the striker which you need to reach at the end. Also turret placement is important so it can kill a lot of people without dieing so try to copy our placement exactly. Keep a look out to where we stand in the buildings b/c its a little different and much better then most videos. Enjoy!!
