Care Package

 is a multiplayer kill streak reward in Call of Duty: Modern Warfare 2. After achieving a 4-kill streak (killing 4 enemy players in a row without dying) the player is given a special red smoke grenade. A helicopter drops down a package of crates, which the player can then pick up to receive extra ammunition or a random kill streak reward. The lower kill streaks and ammunition are more common, but it is still entirely possible to receive a higher kill streak reward such as the AC-130. The care package can be stolen by enemies and teammates, and can also land on top of buildings, or on the wrong side of map barriers where it cannot be reached by the player, so the player must be careful where they place it.

Care Packages appear on the radar. Friendly care packages are green while enemy care packages are red. Like Tactical Insertion, the player can choose to forego using the package, and instead use it as bait for ambushing an unsuspecting enemy, but be warned that enemies can kill the player and then take the package for themselves.

Trivia

 * The Care Package can kill any player that it lands or bounces/rolls on.
 * Emergency Airdrops, and other Care Packages cannot be obtained from the Care Package.
 * Kills earned via kill streak perks from a Care Package and Emergency Airdrop do not count towards a player's kill streak. However, killing an enemy by having the crate crush them does count towards the player's kill streak.
 * If opening a Care Package dropped by anybody other than the player, it takes twice as long to open.
 * Furthermore, the player will only get points for opening their own Care Package, and no one elses, and will not gain points for activating kill streak rewards gained from the Care Package.
 * If an ally does take the player's Care Package, the person that called in the care package will get bonus points along with a message that says "Share Package".
 * Though a difficult feat due to the small amount of time it spends on the map, the care package helicopter can be shot down with Stinger missiles, etc. However, no points are awarded to the player that manages to do so, so the only result is the loss of a missile. An exception to this would be if the chopper was shot down before dropping the care package, although this is nearly impossible.
