The OriCon Expeditionary Force is OriCon's primary military presence in the Golden Branch Star Sector. Based out of the planet Archonic, it is tasked with maintaining peace in OriCon controlled systems, protecting OriCon corporations and furthering the goals of OriCon.

With the recent secession of EarthHome Entertainment and Snowtrak Heavy Industries from Oricon Golden Branch Board of Trustees, the responsibility of confronting these renegade corporations would normally fall to the Expeditionary Force. However the commander of the OEF felt the task exceeded their capabilities and enlisted the aid of the only major loyal OriCon corporation, Minerva Mining and Mechanics. In exchange for the financial and industrial suupport of Minerva, the Expeditionary Force placed itself at the disposal of Minerva for the duration of the crisis forming the Minerva Strategic Alliance.
