Hints & Tips

Go around corner with low profile
If you happen to be in an urban area and want to go around a corner while keeping a low profile, roll around the corner by going prone and strafing.

Avoiding damage when in a building
When you are in urban areas, roughly half of the damage comes when you are in a building. Have all the teammates (except Foley; if there is a second floor put him at a window) cover a door or entryway.

Avoiding damage from fire
Whenever you are on fire from a grenade or rocket, drop to the ground and roll. Once you do this, the fire will be put out and will stop hurting you.

Healing falling teammates
If one of your teammates happens to fall to the ground, throw a smoke grenade near him. Then, get your health packet out and heal him.

Destroying armored vehicle or tanks
You can use Jones to run up to the vehicle or tank. Lay an anti-tank mine next to it, in turn sacrificing Jones temporarily to knock out the vehicle or tank.

You can use Jones to run close to the tank, then plant a C4. Throw a smoke grenade on the tank, run for the closest cover, then blow it up.

Have one of your team members run by the tank to distract it. Then, run up to the tank, plant C4, and blow it up. You can heal him by using the other team members.

Tanks are weak in these spots: their rear; in front, in between the armor over the tracks; and where the gun barrel meets the turret.

Throw a smoke grenade in front of a tank. Then, lay mine or C4 in front of it or just shoot it with an anti-tank rocket in the front.

Air Cover mission: SAM destruction
SAMs can be destroyed by shooting them with any gun. Make sure to save the C4 for the larger tanks.

When you have cleared all resistance near the plane and are in a large hall, go up the stairs and you can find a few windows. You can see SAMs through the window. It is easier to destroy them from here with grenades or any other weapon. Note: After destroying the SAMs from the window and you are ready to go forward in the map, place claymore mines in the corridors. If you place all your claymores there, you will not have any problems with the enemy soldiers who are coming from the back.

Air Cover: Two tanks at last SAM
At the final SAM, there is a tank behind a building. This is after the conveyer belts. Have Bradley pick up an Iraqi gun earlier in the mission. When you get to the tank behind the building, give this weapon to Foley so that he and Connors can cover the door where the conveyer belts are at. Once that is done, tell Jones to follow you to the entrance leading outside but do not go out yet. Use Bradley's Grenade Gun by going to your inventory and pressing R1(2x's) on the Colt Machine gun. Shoot the grenade close to the building with the steel structure. The tank will then come out, but hide behind the steel structure. Switch to your regular gun and start shooting the Iraqis that come out of the building. After that, throw a smoke grenade so that you can reach the barrier without the tank shooting at you. Switch back to the Grenade Launcher on your Colt machine gun and shoot the SAM hidden behind the truck to your right. You will have finished that objective. Then, go to your left to where you will see a shadowy passageway. Shoot your Grenade Launcher over to this area. Instantly, another tank will come into view. Switch back to the Colt machine gun's burst fire. You should have picked up RPGs close to the beginning of the mission. Throw a smoke grenade or two and fire your RPG at the second tank. If you aimed properly, you should have killed it. Do the same thing to the first tank. Then, go inside the building.

Clear room without a door
For you to clear a room without a door, first throw a phosphorous grenade in. Then, have Jones follow you and have Foley and Connors cover the entrance. Then, tell Jones to rush the opposite side of the room. Also move in at the same time and rush a corner, gunning down any resistance. If there is a door, then position someone with an automatic weapon facing the door, then open the door and back off while Connors polishes off any enemies. Then, rush the room and tell Connors to follow you and shoot anything that happens to move.

Scouting
When you are moving ahead to scout a location, always leave your squad in a good position that they can cover you from, and in a pinch lay down some suppressive fire. Even if they do not hit the enemy, it will make them hit the dirt.

POWs In Baghdad mission: Destroying tanks
When you first come across the tank, the easiest way to destroy it is like this: First, get rid of all foot soldiers. Then, throw two or three smoke grenades at the machine gun bunker. Move directly to the house with the machine gun bunker, taking out the gunner as you run. Make sure the squad holds in a safe location away from the tank. Drop to a prone position and crawl through the house to the other door. Run along the wall until you get to an opening on the left. You should see the back of the tank. If needed, throw another smoke grenade at the tank and move to the rear. Drop on a knee and shoot the rear of the tank. It should be demolished On the second tank, give all the other smoke grenades to one person and move them to the top of the stairs. Throw them at the tank. Order the squad to fall in and run to the GAZ jeep.

POWs In Baghdad mission: Easy completion
When you start, proceed to the left. You will see a desk. Go to it and pick up the weapons. Then, go outside. The alarm will be set off. Attempt to shoot everybody in the area. Go into buildings, because a few of them have weapons, ammunition, and health packs. When you find one of your teammates, open the cell. Give him one of your weapons and a health pack. Try to find the spot that is all red. When you get out, follow the path to get to an area with a lot of enemies. Ignore them and let your men kill them. Get your man with the bazooka out. Run to the left to locate a tank. Use the bazooka on it. You will then be in a building. Go through it and you will be outside.

Victor Two level: First tank
When you get to the third area where you see the first heavy tank, be silent. The tank crew is standing behind the tank. Have Conners and Foley kill them before they know that you are there, and before they can get inside of the tank.

CPU control
Change to a different soldier and stay idle (do not move, switch a weapon, or fire). The CPU will still be in control of that person. Note: The CPU will not move unless you switch during one of the commands. The CPU will only fires at enemies.

Besieged mission
In order to finish this mission, you must have snipers on top of the building in order to win that battle. Just place a tank mine by a dirt hill-looking place then put down three claymores by the second hill. Even though the claymores will not annihilate the tank, they will let you know you that the tank is coming and will slow it down a bit. When you finish that, have everyone run to the gate where the Delta team will C4 the door. Run in swiftly and have everyone inside there is a heavy duty tank coming.

POWs In Baghdad mission: Powerful weapon
From where you begin, turn left and pick up the guns on the table. Then, turn around and wait for the door to open. Take out the guard and pass through the door. Turn left and take out this guard. Continue down the hall, turn left, and take out this guard. Go to the door where the guard came out of and prepare for another guard. After the guard is down, run to the desk to pick up an 870 combat shotgun with seven rounds. You could lose some health and ammunition, but the reward is a really powerful weapon.
