Get Into Position and Breach the HQ Building
All you have to do is follow your team-mates to the building and wait for them to break down the door, with two enemies inside (stunned by the breaching). However, it is actually possible to be first in and to take them down before your teammates do; this can be done with the M9 pistol.

Search the HQ Building for Khaled Al-Asad
First, as you enter the door, there will be two enemies, your team and you will take care of them easily. After that you will encounter some more enemies when you go down the stairs, one will stay in front of you so kill him, the other two will go right, wait until your squad comes watching the door to your left, two enemies and some enemy intelligence are in there, take out the enemies to the right but watch out in case the one or two enemies from the left attack you. If they don't then about two or three more will come, kill them, then go left and clear out the room, one enemy may behind the filing cabinet, right behind the door, just start firing as you go into the room.

You will see some weapons on the table, and on the ground there should be some AK-47s, you are probably best to get the W1200 Shotgun or the AK-47 as they are both good weapons, the AK is probably the best choice as many enemies have it, it is good for long range and you can pick up the shotgun later, where you need it more.

Now, go to the door where the two enemies were, throw a flashbang in as told to. You don't need to but it gets it done a lot more safely, just leave your squad to pick off the blinded enemies.

Regroup with 1st Squad
Go back outside and carry on down the road to regroup, don't worry about the dead guards all around the compound, no enemies are actually there. When you meet First Squad there will be a lot of enemies in front of you and about three to the left (one standing, two on the rooftops). You are probably best to shoot the car where the enemies are hiding so it explodes (Xbox 360 players may get an achievement if it kills more than 1 person). Next, go to the right and attack the enemies as they move to the car near you, they will die very quickly.

Make Your Way to the TV Station
Now, go forward and you will come to a fairly big courtyard with a wooden fence, go to the right and you will see a shack, enemies will soon come off the roof of that, follow the fence round but behind the barrel, an enemy will come out so be careful, when he's disposed of, go round the corner, loads of enemies will be firing through the gaps in the wooden fence so kill them all and let your squad advance, maybe go back the finish off the two enemies that came off the roof then go on.

Now, you will come to a safe point, but in front of you is a lot of enemies, you may want to get out a sniper rifle if you can find one and go forward, you will see some enemies on a building, kill them then toss a grenade in, now get out your other weapon and find some cover and kill the enemies in front of you, then when you think many of them are dead, rush up the stairs and kill any remaining enemies, now you are closer to the enemies so kill the rest of them with your squad who will advance as well.
