Kill Streaks

3 Kills - Recon Plane

Kill three enemies without dying and you are given the ability to call in a recon plane to mark enemies temporarily on your radar map. The only enemies that won't appear are ones using the Reconnaissance perk.

5 Kills - Artillery Strike

Kill five enemies without dying and you are given the ability to call in an artillery strike. This is very similar to the Airstrike command in COD4, however, instead of a line of bombs going off, the area in which you select for the drop is completely obliterated in a long series of cannon fire.

7 Kills - Unleash the dogs

Kill seven enemies without dying and you enable the ability to call in attack dogs, which will sniff out any enemies on the map. Unlike COD4, attack dogs will find you regardless of where you hide, making it exceedingly difficult to avoid them. Furthermore, killing the attack dogs will only save you temporarily as the hounds will respawn if killed until their time limit/ kill limit has expired.
