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.

Search the HQ Building for Khaled Al-Asad
Now you will encounter some 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 right, two enemies and some enemy intelligence are in there, one enemy usually comes out, so kill him, after this, take out the two to the right if your squad-mates haven't already and then go into the room, kill the enemy and get the intelligence.

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, go directly to the right and kill the enemy, then, sticking to the outside wall, go forwards and kill the other enemy, there may be one or two in front of you, so take care of those. The building will be found to be empty. You could toss a flash bang in the room if you want, but in arcade mode it will rake up more kills for you. If it doesn't really matter then throw the grenade because it isn't really needed anywhere else.

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.
