Airstrike

From Call of Duty - Wiki on Neoseeker

After you have acheived 5 consecutive kills on the enemy team you are rewarded an Airstrike. Once used a clear map will show up and you place the marker where you want the airstrike to hit. 3 Jets fly over, and one after the other drop a series of bombs causing a mass explosion. You are rewarded 10 points for calling in an airstrike.

Used in conjunction with an UAV, you can drop your airstrike right on top of your enemies.
