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 green 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.
