Air Traffic Control: Get Two Helicopters Easily
When you begin the Air Traffic Control level, you will start out as a sniper. Directly behind you is a chopper. Turn around as soon as the level begins if you want a good shot. You should be able to shoot him and the chopper will fall a short distance directly in front of you. Make sure you hit the pilot, and not the chopper. It may require a few attempts to hit the pilot. It will not explode. You can then get in and shoot out the turrets with the chopper. When the jeeps come by, hotswap to one and go directly past the turrets and into the helicopter inside the heliport. You have now acquired two helicopters, making this level very easy.

The only ways to avoid a GTAM is to either immediately bail out, dodge a couple buildings, or have an artillery strike fall on top of you.
When in multi-player mode and flying a helicopter, if you start to get laser targeted (not GTAM), fly as fast as possible, and at the same time get as low to the ground as possible. By doing this, the missile will hit the ground and miss you almost all the time, if done correctly.

Multi-player Mode: Unlimited C4
In online multi-player mode, start out with a Spec Ops. Then kill yourself. Make sure to know where you were in order to reach the weapons pack you left behind. Then, play as a Spec Ops again. Go to where your weapons pack was deposited. Switch to your C4 and throw one, but do not detonate. Then, switch weapons pack. Next, use another C4 and do not detonate. You will not run out of C4s as long as you keep switching packs. Repeat these steps and one of the weapons packs should contain as many C4s as when you switched packs. This can also lead to a large explosion if your C4s were thrown near each other. However, this glitch is only limited to the immediate area unless you wish to walk back and forth from your target or you killed yourself near your target (for example, a large explosion with a helicopter, tank, or jeep and use the mass amount of C4s as a kamikaze attack).
