Joint Occupation Zone

Joint-Occupation Zones (JO Zones) are regions of space that are jointly administrated by the Phoenix Initiative and Concord of Reconciliation.

History
The first Joint-Occupation Zones were several sites tentatively established with the Treaty of Arusha ratified in 2553. However, issues with military jurisdiction and commercial control led to more effective terms in the Luna Accords of 2556.

Major zones
The main Joint-Occupation Zones are defined as the frontier regions between the Human Sphere and the Holy Ecumene. They terminate on one side in the furthest-flung human worlds under Phoenix Initiative or UNSC jurisdiction, and the hazy marches of the Covenant on the other. Because of the diffuse nature of frontiers on both sides, unofficial, lawless and unrecorded settlements abound within the zones. Most of the habitation within the zones is built on logistical infrastructure established by the Covenant during the Human-Covenant War. The space covered by the zones also encompasses various official colonies recognized by the major factions, some of which are exempt from the joint occupation arrangement.
