Field Upgrades (Battlefield 4)



Specializations in Battlefield 4 are utilized through the Field Upgrade system from Battlefield 2142. There are over 25 different specializations available for use when choosing from the 11 available Upgrade Paths. Each path holds up to four different specializations that are obtained by progress chained by squad-based team work.

Three of these specializations are initially locked. As the squad completes objectives, or the squad is granted a promotion by the commander, the remaining specializations are unlocked and stack. If everyone in the squad is simultaneously either dead or has not deployed, however, then the squad loses one specialization each time that happens. This system replaces the collaborative system in Battlefield 3 and the potential waste if squadmates selected the same specialization. Upstanding upgrades at the end of rounds will be carried over to consecutive matches on that server.

Vehicle specializations follow the same system as in Battlefield 3, but with optics and gadgets in separate slots, and gunner customization for additional vehicle types.
