The loadout system in Modern Warfare 3 has seen significant changes compared to previous Call of Duty games. While you can still carry two weapons and have a wide selection of Tacticals and Lethals at your disposal, the Perk system has undergone a complete overhaul. Perks are now distributed across different gear components, including Vests, Gloves, Boots, and Gear.
Field Upgrades are the final piece of the puzzle in your Modern Warfare 3 loadout. And while they are not vastly different from Field Equipment in MW2, the available selections have evolved.
In this article, we’ll take an in-depth look at all the Field Upgrades available at launch and explore the benefits they bring to your CoD: MW3 Multiplayer experience.
All 18 Field Upgrades in MW3
Field Upgrades are special equipment that you can use to aid you and your team offensively or defensively. These upgrades have a set recharge period (cooldown) before you can use them again.
Depending on the Vest you’ve equipped, you may carry one or none from the following list of 18 unique Field Upgrades in Modern Warfare III:

1 | Heartbeat Sensor | A limited use tablet that displays rough information about nearby enemies. |

3 | Inflatable Decoy | Proximity-activated decoy mine. Upon activation, the reinforced fiber target is violently deployed to confuse and distract. Press the ‘Tactical and Lethal’ buttons together a second time for manual activation. |
4 | Comm Scrambler | Disables communication with intel within its radius. Enemies will not be able to activate killstreaks. Enemy UAV and intel systems will not detect you and your teammates. Location of the scrambler is visible on the enemy minimap. |
