Battlefield: Bad Company 2/Specializations

Specializations are modifications or improvements players can equip to give them an edge in combat. Specializations are usually unlocked by rank, though some are unlocked via combat experience. Which specializations are available depends on the selected class and occasionally the weapons equipped.

Specializations come in three tiers: primary, secondary, and vehicle. Players can choose to equip one of each, with primary and secondary specializations applying to the player and the vehicle specializations obviously improving vehicles.

All Kits
These specializations are available to all kits. The two shotgun modifications are listed here, as shotguns can be equipped by any of the four classes (including the otherwise long-range recon class). Obviously, players must equip a shotgun in order to use the two shotgun upgrades.

Vehicle
The vehicle tier is a tier on its own. Note that with the sole exception of helicopters, only the specialization of the driver applies to the vehicle. Specializations, in other words, do not stack: two quick reload upgrades will not fire faster than a single reload upgrade. The passengers, if they have weapons, do not gain any bonuses.

The exception to the above rule is the gunner seat of an attack helicopter. If the driver chooses the alternate weapon vehicle specialization, his gunner gains the ability to shoot tracer darts at targets. The pilot, meanwhile, can use guided missiles as well as the standard rocket system. The guided missiles can lock onto any target the gunner tagged with the tracer darts. The gunner's vehicle specialization does not apply.

Only one of the following may be equipped at any time.
