Call of Duty 4: Modern Warfare/Death from Above

From StrategyWiki, the free strategy guide and walkthrough wiki

AC-130 Gunship
The guns on the AC-130 are different from the normal guns, you have 3 to choose from: a 25mm gun, a 40mm gun and a 105mm cannon. You should not need to use the 25mm gun in this level unless you are worried about hitting your troops, you should alternate between the 105mm and 40mm as the 105mm gun has a long recharge time.

Death from above is a different level because instead of being a troop on the ground, you are in an AC-130 Gunship, assisting your squad-mates.

[edit] Provide AC-130 Gunship Support for Friendly Ground Units

Do not shoot the church

First you will see a church, watch out for this, if you fire on it or even some shrapnel hits it. You should use the 105mm Cannon to take out the vehicles then switch to the 40mm cannon and take out any enemy groups you see, watch out for flashing people as they are friendlies. Just keep on killing any enemy you see until you hear about a truck on the highway. Wait until the truck passes, do NOT attack it.

You will now go to a village, you will see a few men and a truck near the trees, shoot then with the 105mm Cannon. Then switch to the 40mm Cannon and attack the people on the rooftops of buildings. Keep on killing anyone you see, but watch out when your men come through, you may want to switch to the 25mm gun if there is anyone to finish off.

You will eventually go to the Junkyard, may enemies in big groups will be around, many come from a U-Spared building, so look back there sometimes. Switch between the 105 and 40 mm guns as the 25mm is fairly useless against big enemy groups, if a few slip away, then use that to get them then go back to the big guns. Captain Price will be on foot so watch out for his squad. Two helicopters will arrive, so cover them and then the mission will be complete.
