frequency or percentages of care packages dropped in an emergency air drop.

Try to not land the care packages outside the map like a complete MW2 noob. The plane always comes from the opposite direction that you're looking towards (when throwing the care package flare) and flies straight, never turns or any tricky stuff.
Here is the list of frequency or percentages of care packages dropped in an emergency air drop in call of duty modern warfare 2. People always ask me and I figured I would post this. And one other important note, it works better when you ask a team-mate to help you because more than likely enemies will sprint towards the crates, works better if you do it while a friendly harrier is in the air or any friendly aircraft.

Care Packages, Emergency Airdrops, EMPs and Tactical Nukes can't be acquired from the packages. Below are the drop rates:

12% of the time in care packages - Ammo
12% of the time in care packages - UAV
16% of the time in care packages - Counter-UAV
16% of the time in care packages - Sentry Gun
14% of the time in care packages - Predator Missile
10% of the time in care packages - Precision Airstrike
5% of the time in care packages - Harrier Strike
5% of the time in care packages - Attack Helicopter
3% of the time in care packages - Pave Low
3% of the time in care packages - Stealth Bomber
2% of the time in care packages - Chopper Gunner
2% of the time in care packages - AC-130

I personally hate when a person (other than me - hypocrite) gets an ac-130 or chopper gunner and then goes on to win the game because my stupid team-mates feel the need to run around in the open without cold-blooded. I once lost a game for that reason when we were 20 kills up before the emergency air drop. I hate MW2 but I love it more. Husla3x
