Follow Soap and listen to Price's instructions until you split up. At that point, Soap will be the one to give you instructions. At the first group, you will have to take out both snipers yourself but then soap will take out the two on the ground.
The second group only requires you to shoot one and Soap will take out the other at the same time. And when you get to your last group where there's whole group of 20+ enemies, don't actually shoot, just line the shot up.
After that you'll be thrown into a shootout. Take cover and clear the area to the north. Up a head a little ways, you'll find an RPG up against some boxes. Find this because you'll have a tank to blow up momentarily. Once he's toast, head into the building on the left. Make your way through the building following the waypoints. Once you get back outside, you'll have to get rid of couple turrets on the second and third floor of the building to the right. Get rid of them and follow the wall around the corner.
After that you just follow Soap for a little while longer. When you enter the next building, you'll have to kill two enemies and then clear a room full of reinforcements. Feel free to go loud. Play some more Simon says after that to finish the mission.
