Reach Station Gamma was a UNSC Space Station located in orbit around planet Reach. It was essentially a ring, three kilometers in diameter, with docking bays and communications dishes covering the surface of the station. It was run by a Dockmaster AI named Doppler.
Moments before the Fall of Reach in 2552, Gamma Station received a transmission from Remote Scanning Outpost Fermion reporting an unconfirmed in-system Slipspace rupture - the arrival of the Covenant fleet.
During the Fall of Reach, three Spartans, John-117, Linda-058, and James-005 took a Pelican to Reach Station Gamma. An ONI Prowler, the Circumference, had docked in the station, but the Dockmaster AI failed to delete its NAV database. Covenant intrusion software had detected the unsecured database and three Covenant frigates were sent to secure the data. Those frigates were destroyed by MAC rounds from the planet's orbital guns, as well as firepower from the UNSC Pillar of Autumn, but not before they dispatched Sangheili and Kig-Yar rangers to secure the data. Eventually, John-117 was able to destroy the database but both Linda-058 and James were casualties. Several marines were on board the station: Sergeant Johnson, Privates Jenkins, Bisenti, and O'Brien. They were evacuated along with the Spartans. The station continued to operate however damaged with a large scale battle occurring near it until its destruction.
