In Call of Duty: Modern Warfare 3 for the PC, PS3, Wii, and Xbox 360, killstreaks are now called Strike Packages. The Strike Packages are quite different in this version of the game, since they have added multiple multiple Strike Packages to choose from depending on your play style.
You’ll notice that the Tactical Nuke is gone, but it has been replaced with something much better, something call the M.O.A.B. It’s still a 25 point killstreak reward, however it doesn’t end the match, and you must get it with your weapons alone, other strike packages don’t count toward it. It’s also hidden, and there are no unlockables whatsoever associated with it, so boosters won’t benefit from it. Check out my other guide for more information about the M.O.A.B and how it works.
Assault Strike Package
The Assault Strike Package is similar to the regular killstreaks from Modern Warfare 2, in that your streaks reset when you die, and kills from Strike Packages count toward your streak.
UAV – 3 kills
Care Package – 4 kills
I.M.S. (Intelligent Munitions System) – 5 kills
Predator Missile – 5 kills
Sentry Gun – 5 kills
Precision Airstrike – 6 kills
Attack Helicopter – 7 kills
Strafe Run – 9 kills
Little Big Guard – 9 kills
Reaper – 9 kills
Assault Drone – 10 kills
AC-130 – 12 kills
Pave Low – 12 kills
Juggernaut – 15 kills
Osprey Gunner – 17 kills
Support Strike Package
The Support Strike Package is a new set of killstreaks, and is the only package that does not reset your streak when you die. The Support package seems to be geared more toward the team player, and players that have a hard time getting killstreaks.
UAV – 4 kills
Counter-UAV – 5 kills
Ballistic Vests – 5 kills
Airdrop Trap – 5 kills
Sam Turret – 8 kills
Recon Drone – 10 kills

EMP – 18 kills
Juggernaut Recon – 18 kills
Escort Airdrop – 18 kills
Specialist Strike Package
The Specialist Strike Package is a new set of streaks that give you extra perks for kills the regular support from other packages. Nearly any perk can be setup to be used with the Specialist, with the exception of the Overkill perk. Your streak resets when you die, similar to the Assault Strike Package.
One extra perk – 2 kills
Two extra perks – 4 kills
Three extra perks – 6 kills
All perks – 8 kills
