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. Active Armor Upgrade is canceled out by Improved Warheads Package and Improved Demolitions.
