Upgrade Path

An Upgrade Path is a series of four Specializations per path in Battlefield 4 that are progressively unlocked through squad actions in a match. There are a total of eleven upgrade paths, with three paths available for all classes and two paths unique to each class.

Paths can be freely chosen anytime during matches with progress for each path saved whenever a new path is chosen, a kit has been changed, or a new squad has been joined. Some progress, however, is lost for the path currently in use whenever the player and their squad have been wiped.
