Call of Duty: Modern Warfare 3 Strike Packages

Killstreaks are bonuses that are earned by killing multiple enemies in a row without dying or gaining points by completing objectives. You can lower the required amount by 1 with the Hardline perk. Killstreaks are divided into 3 Strike Packages: Assault, Support and Specialist.

MOAB (25 kills)

The MOAB (Mother of All Bombs) is a hidden killstreak available with any Strike Package. It's earned by getting a 25 killstreak, not including Strike Package kills. The MOAB works pretty much like the Tactical Nuke from Modern Warfare 2; it kills every enemy on the map and causes an EMP-effect for the enemy team by eliminating all enemy equipment, electronics and killstreaks for 1 minute.
The MOAB doesn't end the match. The team that uses the MOAB will have double XP for the remainder of that match.

Assault Strike Package

UAV (3 kills)

Shows enemies on the radar as red dots for 30 seconds. Enemies that have the Assassin perk equipped are not shown on the radar.

Care Package (4 kills)

The Care Package is dropped to the battlefield and contains a random killstreak. The Care Package can be picked up by anyone, even the enemy.

I.M.S. (5 kills)

The Intelligent Munitions System is automatically triggered once an enemy gets near it. It has 4 anti-personnel grenades that explode in the air.

Predator Missile (5 kills)

Allows you to remote control one Predator Missile to the ground.

Sentry Gun (5 kills)

Airdrops a placeable Sentry Gun that automatically attacks enemies once deployed. Players using the Blind Eye perk won't be attacked by Sentry Guns.

Precision Airstrike (6 kills)

Allows you to call in a directional airstrike.

Attack Helicopter (7 kills)

Calls in an Attack Helicopter that flies around the map and attacks enemies for a short while.

Strafe Run (9 kills)

Calls in five helicopters to sweep the indicated area with massive firepower.

AH-6 Overwatch (9 kills)

The AH-6 Overwatch flies in and provides personal protection by following you and attacking enemies that you come across.

Reaper (9 kills)

Take control of a Reaper-UAV and use it to launch 14 laser-guided missiles to the ground.

Assault Drone (10 kills)

Airdrops an Assault Drone that you can control. The Assault Drone is equipped with a Light Machine Gun and a Rocket Launcher.

AC130 (12 kills)

Be the gunner of an AC130 for 30 seconds. Use the 25mm, 45mm and 105mm guns to attack enemies.

Pave Low (12 kills)

Heavily armored assault helicopter that attacks enemies. The Pave Low is harder to destroy and packs a bigger punch than the regular Attack Helicopter.

Juggernaut (15 kills)

Receive the Juggernaut suit, equipped with the M60E4 LMG and MP412 handgun. Lowers mobility, but makes you more resistant to damage.

Osprey Gunner (17 kills)

Be the gunner of an Osprey that drops Care Packages. It's pretty similar to the Chopper Gunner from Call of Duty: Modern Warfare 2.
