M1A2 Abrams tank got stuck in a bog and your team needs to help it. You start the mission on a highway. You're under heavy attack...
Go straight (#47), watch out for the bullets flying over your head. You will see a passage going through a fence. (#48) Use it. You'll get into a building full of enemies. Activate your night vision (#49).
Go upstairs with Roycewicz and eliminate the terrorists that are taken aback. Clear all the rooms, and get to a machine gun (#50) Use it to kill the terrorists on the other side of the building. Then get downstairs and wait for marines to open the door (#51) leading to the other part of the city. Deactivate your night vision.
The yard is taken over by the Arabs. Head left (#52), eliminating all the enemies and trying not to get hit. Use the concrete barricades as your shield , and walk the yard around (#53). Then kill the terrorists. Get inside the building and kill the rest of them. Don't forget about enemies on the first floor. (#54).
Two enemy tanks will show up on the overpass. Of course, you will be responsible for destroying them. Go downstairs and outside the building. Then pick up the Javelin (#55). Aim for the target (hold down RMB when aiming and destroy both vehicles (#56). When it's done, your teammates will cut through a fence (#57). Follow them.
Not bothered by anyone, you will get to the tank stuck in the middle of some kind of field (#58). Terrorists are trying to destroy it. Get behind the tank (you won't get hit there) and start the annihilation of the enemies. Don't try to be a hero on your own, just focus on defending the tank. Listen to your teammates as they will inform you about the directions of the attack. Primary targets are soldiers with RPGs, cause only they can destroy the tank.
After you accomplish this objective, you will get another one. You will have to blow up AAA gun, that is efficiently keeping American air forces out of the zone.
Head towards south-eastern part of the field (#59), eliminating any resistance. To get to the target you will have to walk through a little building (#60). Kill the soldier operating the AAA gun and plant the explosives (#61). Then get to some safe place and blow it up.
When AAA gun is no longer a problem you can call in air force. Head north to the other side of the bog. You should notice a spot (#62), at which you will have to use the beacon marker. When you do this, helicopters will do the rest (#63). After it's over get back to the tank (#64), that luckily survived the siege...
