FOB
A forward operating base that turns a contested Zone into a held one.
A FOB, or forward operating base, anchors your team's presence on the Control Zone: cover, fighting positions, and a place to fall back to. It is built with the Support career's build tools, the Hammers, after buying the FOB from the vendor.
Building and defending
Site it to cover the approaches, layer it, and keep infantry inside with Tanks on the approaches and Anti-Air overhead. Its biggest threat is Artillery, the SPH-2 is built to break FOBs from range. Plan one in the free FOB Builder, and read the FOB guide.
