— In-game description
The Active Armor Upgrade is a vehicle specialization featured in Battlefield: Bad Company 2 and is obtained after acquiring 2300 experience points with any vehicle or emplacement.
The Active Armor Upgrade reduces the damage taken by 25%, and is a passive specialization, meaning that it does not require user input to activate as it will always be activated the instant a player uses a vehicle or emplacement and will deactivate upon leaving unless another player in the vehicle has the same specialization.
The upgrade is best used as a driver of a transport vehicle such as a HMMWV, a PBL, or a UH-60 Black Hawk, as they are generally weaker targets and can be taken out with one hit by a rocket or tank shell.
- Although the game description states that the Active Armor Upgrade increases armor, it actually reduces all damage taken.
