Call of Duty 4: Modern Warfare/All Ghillied Up

Follow Captain MacMillan
In this mission, you play as Lieutenant Price, under the command of Captain Macmillan and are sent into the outskirts of Chernobyl to assassinate Imran Zhakeav.

When the mission starts, follow Cpt. Macmillan to the small shed and he will tell you that he sees two enemies to the North. Stay low and move up to a good firing position. You can take Cpt. Macmillan's advice and shoot one while the other isn't looking. After you have done that, follow Cpt. MacMillan up to the house. Cpt. Macmillan tells you that there are four enemies in the house, do not try to take them out, you will die!.Just take out the enemy patrolling near the car and move up. Hop over the fence, and Cpt. Macmillan will tell you that he's spotted two enemies, a lookout in the church tower, and one near the car.

Move to the corner of the building to the left, from here you will have a clear shot that the enemy in the Church tower, then take out the other enemy near the car. Enter the church and go up to the tower to get some enemy intelligence, you may want to swap your pistol for a Stinger in the church tower although you won't need it unless you alert the enemies with a helicopter overhead. Go through the graveyard, and when Cpt. Macmillan says, go prone so the helicopter doesn't spot you. Jump over the pipes and be ready to go prone. An enemy armoured column is advancing toward you. Stay prone, and get right behind Capt. MacMillan, go slightly to the left and wait for everyone to pass you unnoticed. When the coast is clear, move up. You'll then be in an area with many enemies. Sneak by them and don't shoot, and you'll be fine. You'll then come to an area full of cargo containers. Follow Cpt. Macmillan's orders, and you'll get through here without a problem. You might want to disobey them for a bit as there is a piece of enemy intelligence here but it is guarded by 3 enemies, one is sleeping right next to it while the other two are patrolling, just go prone, get right next to the intelligence, crouch and get it then go prone again and go back to where Cpt. MacMillan is.

You'll then need to sneak through an enemy vehicle convoy. Stay close to Cpt. Macmillan and you won't be spotted. Afterwards, take out the enemy sniper so you won't be spotted, you can go up to to where he was and go through the window for some intelligence. Now enter the building through the first floor window. Keep your distance from the wild dog so it won't attack and keep moving through the city until you reach the target building.
