When you can move, head up the left side and up the stairs at the back to gain little bit of elevation. Get a few kills and then use the chopper gunner to clean up as many enemies as you can. Once you regain control, clear out any remaining enemies and head west, then north. You'll come nose to nose with another truck but it's actually blow up after just a little bit of gun fire.
Wait for the chopper to come back and take another pass, making sure to blow up any vehicles you may see. Thin out the other enemies and when you are beckon your feet, head around that corner past the truck. Head up the hill. Go into the building at the top of the hill. You won't meet any real resistance until you meet back up with Soap. After that, you'll go through a door and have to clear a bigger room but you'll have flanked the enemy making it an easy cleanup. Go to the door at the back and breach. When you breach, just make sure you don't shoot the target that says "capture."
Exit through the back of the building and follow Soap and Price to a bigger plaza where you'll be attacked by snipers and RPGs. Take cover. This next section is a race against the clock. You'll have to push forward aggressively to make it so try and get kills as quickly as possible. Don't worry too much about ammo. Go to the end and take a right. Clear the roof tops here and take left. Again, you'll come to more rooftop and balcony enemies but don't attack them just yet. If you take a sharp left, you can cut through an alley and flank those enemies. Clear them out and enter the bottom floor of the building and clear to the top. Once you've done that, head outside and follow the alley to the right of the building.
In the next area you will need to climb a building under construction. Clear each floor as you go and when you get to the top, take control of the chopper gun to clean up the LZ. Once the Sandstorm envelopes you, just follow the markers and do as Price says. Keep moving through the storm until you find Nikolai. When you find him, you'll have to pick him up and carry him. Just keep moving for the waypoints because you can't take damage while carrying him. Once you go down the hill, you'll have to make your way to a jeep without Nikolai to end the mission.
