A Forward Operating Base or FOB is a general term used to describe any secured military position established for the purposes of supporting strategic and/or tactical goals on a battlefield.


Forward Operating Bases have been utilized by human military forces for centuries. The Covenant also utilized FOBs during the Human-Covenant War.[1]

The crew of the UNSC Spirit of Fire installed FOBs in their campaign against the Banished, with FOB Quebec being one of them.[2]

During the Battle for Zeta Halo, the surviving UNSC personnel from the UNSC Infinity set up at least twelve Forward Operating Bases on the fragmented section of Zeta Halo.[3] The bases were hastily deployed to monitor Banished activities and launch incursions against raiding parties, supply depots, and other targets.[4] However, by March 3, 2560, all twelve FOBs had fallen into Banished hands.[3] They would remain that way until May 28, 2560, when John-117 arrived on the ring and began retaking the FOBs, starting with FOB Golf.[5]

In-game information[edit]

Captured FOBs[edit]

They can also be used for fast travel. Recapturing a FOB will also reveal additional targets in the surrounding area.[5]

Capturing a FOB earns the player the Reclaimer achievement, while capturing all twelve FOBs earns the player the Resurgency achievement.
