Fireteam > Fire at will!

Okay, over the water and where the right entrance to the fort is, there are two terrorists, take them out (you can walk up to them). In the entrance by where the two terrorists were is another, kill him.

Carry on through to delta until you get to a metal gate, simply open it. Go through.

[a] Terrorist on the right corner (by where the smokes coming out the window)
[b] Another further right of him (out in the open)
[c] A terrorist left, where it says ECHO on the left behind a bit of wall.

Follow it around to ECHO, as you go through a doorway with some steps behind it, another terrorist is sitting in the way. Kindly ask him to move, or shoot him. ECHO should now be on your left, go in and get the hostage, restrain her, and tell her to follow you.

Face where you just came in, and tell your fireteam to cover target as some terrorists will come for you, you'll likely need to shoot them yourself though. After 3-4 terrorists have tried to run in, tell your fireteam (while pointing outside) to clear area, and they'll finish the last few off.

[a] Head to FOXTROT (extraction). As you go through a doorway with stairs infront of it, watch out for the terrorist that runs down them.
[b] Turn right towards FOXTROT and there will be 2 terrorists in this open area.
[c] As you get close to FOXTROT two more terrorists will appear, put them down.

She should now just run to the extraction door on the right.

Head to INDIA. Just as you get there, for those who have good eyes, you will see a terrorist in the house up the top, go up the stairs and kill him. Go back down the stairs, and kill the other terrorist sitting there. Head to JULIET.

When you get near to JULIET and can go left or right, head left. Poke your head around the corner, look in the middle, press O (Circle) and go fireteam > clear area.
[a] Head back behind the wall for cover. Aim towards KILO, there is a terrorist on the stairs about half way down - take him out yourself.
[b] Turn around, a terrorist should come from behind, shoot him.
[c] Turn around, back to the stairs where [A] was, another guy is there.
[d] Run into the market yourself now to take out anyone left behind. Usually in the top left (south) behind a market stall there will be a terrorist.
[e] Turn around, look up high, another terrorist.
Walk up the stairs, take him out, and his friend!

Go back down the stairs, turn left through the door, make your way to KILO. Make sure your team is following you.
[a] When you go through a door into a room with crates, run against the crates on the right, and you'll be above a terrorist when he runs in. Shoot him.
[b] Get down, go through the door and turn right. A terrorist will be in front of you on the stairs.

Go up the stairs, and open the red door.
Look at the handle on the left to get the 'open door' action. **Checkpoint saved**

[a] Go right, and right again to KILO! Head up the stairs on your left, when at the top look down to see a tank. Use your designator to take it out!
[b] Look to the left, on the same level as you by some crates (on the right) shoot him! (There is another too, but unless you can see him just leave him).
[c] Depending on how long it took you to blow up the tank there may be another guy around the tank.

Turn around, go back down the stairs and head to LIMA.
[a] Terrorist to the right (by the cart)
[b] Terrorist in front of you
[c] Terrorist to the left by the crates on the corner

Go up the steps on the left. And head towards PAPA after LIMA. As you go into a building there is a terrorist on the right, and another in the next room. Follow it around to the right, and you will now be heading for ROMEO.

NOTE: Before you go in the room, when you do get in make sure you look around the room in the middle (on the tables) there is some Intel lying around there - 2 bits (thanks credit#5)

Open the door!
[a] Terrorist right behind it!
[b] Go in, and turn right, terrorist in front of you.

Now concentrate on the guy in the middle. This is chaotic and hard to explain, basically chase the guy in the middle, but DON'T KILL HIM.

If you have flash bangs, then use them on him! Chuck them in the middle and he should stop.

BONUS: On the table on the left when you enter the middle room are some 'DOCUMENTS' and on another is a 'MAP'- pick these up before you leave if possible, but if Sarwat has ran off just concentrate on him so he doesn't escape.

There are also 3-4 other terrorists on the right in this building, so watch your back.

[ALTERNATIVE - Given by credit#4]
When Sarwat is running away at the end, he pauses twice. Once on the first 'bridge-like' thing, and secondly atop the stairs. When he does, then you throw a flashbang at him and USUALLY he automatically surrenders.

When he does stop, restrain him.
