Capture Enemy Checkpoint
Follow your team to the checkpoint and stand on the dumpster, whenever Captain Price tells you to shoot the guards, shoot them. A headshot is not necessary and the other guard will be alerted so try to kill them quickly.

Afterwards, you can let your team kill all the enemies or you can snipe a few yourself, after they are said to all be dead, swap your pistol for an MP5 and wait for the cutscene.

Pick up the G36C from the tower (swap if for your sniper rifle) and wait for Zakhaev's son's convoy to enter. A few troops will appear out of the vehicles, kill them with the G36C. After they are all dead, your tower will be run down.

Hunt down and capture the son of Zakhaev
When you get back up, follow the objective marker, when you get to a house, get out your MP5 and get ready to shoot a dog coming towards you. Afterwards, you will find yourself heading into a small village, go into the building to the right hand side and go through it until you come to a doorway and window on the other side. Take out the G36C and start attacking enemies through the window with it, as your team comes towards you and you kill most of the enemies, go out of the doorway and use the wall in front of you as cover. When you are told that Zakhaev's son has run, sprint to the side-alley to find him.

Firstly, you will be told that there are some enemies behind a fence to take out, use the G36C to hit them a few times, then turn to your right and equip the MP5, two enemies should come around the corner soon, kill them then go to where they came from. You will be facing the remaining enemies, kill them then go up the stairs to your right, when you are halfway up, let loose a flashbang into the house then go in with the MP5 and spray the two blinded enemies to death. Use the G36C to get the remaining enemies behind the wall then go down the stairs and make your way out onto the street. Using the G36C, look to the of of the building in front of you. Two enemies should be there, shoot them both then continue down the alley to the right. There should be an enemy behind the fallen over dumpster. Now start cooking a grenade and throw it around the corner, there are around 3 enemies here, if the grenade did not get them, then kill the rest of them. Around the next corner is 2 enemies hiding behind a broken car, throw a grenade to separate them then finish them off.

Prone underneath the wall as the helicopter destroys the enemy bunkers, rush in to the building ignoring Zakhaev's son in the window. Go up the stairs, after the doorway, there will be a lot of enemies in the rooms that will come out slowly. You might want to use all of your grenades here as this is the last major part of the mission. Afterwards, go into the room to the left, take out the few remaining enemies in the next room and continue up the stairs. Prone behind the wall as the helicopter kills the remaining enemies then go to the far end of the building and go upstairs to find Zakhaev's son. Whatever you do, he will kill himself, even though he is dead, this will signify the end of the mission.
