Walkthrough
Start off by following Sergeant Foley around the trenches until you come to a concrete wall, on that wall there will be an M14 EBR Scoped sniper rifle, swap your pistol for this. Move left down the wall until you find an easy place to jump over and do this when instructed, go for cover behind any cars, then continue forward to the right entrance to the building. Take cover and snipe all of the enemies on the balcony, you do not need the grenade launcher as most of the enemies are far away from each other. After all the enemies are dead, use the ammo crate near where you came in then go down the corridor to the right. In the second elevator there will be some intelligence, get it then continue forward, when you get in the next room, get close to the right wall and shoot through the window, a lot of enemies will come out of a doorway slowly, after all those are dead, continue forward and go through the corridor, be careful because there may be a few remaining people here, if there aren't then focus your sights on the door at the far end of the room, when it opens, shoot a bullet through it to kill the enemy on the other side. Throw a flashbang round the corner and kill the remaining enemies, then go up to the next floor.

Go into the room on the left, kill any enemies then go down the hallway and there ill be a few enemies on the balcony, usually one in front of you and one to the right. Kill them then go right, in the next area, kill the two enemies near the large gun then pick off the enemies on the balcony behind the gun and then throw a flashbang down the corridor to the left. Kill all the enemies and shoot at the closed door. Pick off the remaining enemies then plant C4 on the gun and use the ammo crate, next go through the door with the enemy behind it. There should be some intelligence in there. After this, go up the stairs and rush forwards, you will see some shadows on a wall, go round the corner and kill the three enemies causing these, then throw a flashbang and go into the room on the left. Kill all the enemies then go forward and clear out the remaining rooms, after going forward for a small but, you will find a doorway to the crow's nest. Use the grenade launcher and/or flashbangs to kill all the enemies then after you're told to get the Sniper rifle, go back and plant all your claymores in good locations (mostly behind corners so enemies can't shoot them).

After you've planted these, use the mounted sniper rifle, after you are told to defend the position, shoot out the hole in the wall and kill the enemies, then use the Javelin to destroy a few vehicles, after you are told to go, sprint through the opened doorway and up the first two flights of stairs, on the left, a door will be opened, kill the one enemy there then go round the outside. Throw any remaining flashbangs and try to kill the enemeis, then go up to the helicopter, go near it to man the minigun. You will go near a World War 2 memorial, there will be two RPG teams on columns and a lot of enemeis in the middle, kill them all. You will now go near a building and have to hit some SAM sites, you will be hit, as you're going down, kill all the RPG troops in the window of the Department of Justice building then the helicopter will crash. You will be given a weapon, you do not have to shoot anything, a spotlight will shine on you and the mission will end.

Intelligence

 * After going inside the building to get to the crows nest, you will come across two elevators after the first room with enemies, in the second elevator there will be intelligence (the doors on the elevator will open and close).
 * After destroying the large anti-aircraft gun with C4, there will be an enemy shooting through a door, kill him and the door will open, inside the small room there will be some intelligence.
