Career
Support
Heavy fire and fortifications.
The Support career is the most varied: it levels from LMGs, shotguns, launchers and the build tools, the Hammers, used to raise a FOB. Support lays down fire and builds the fortifications that turn a contested Control Zone into a held one. One of the six Careers.
