Gamma Station, also known as Reach Station Gamma or Orbital Station Gamma, was a UNSC space station located in orbit around the planet Reach. It was essentially ring-shaped, three kilometers in diameter, with docking bays and communications dishes covering its surface. It was run by a Dockmaster AI named Doppler. The station also possessed a tram system, at least one Sabre repair bay and extensive communications facilities.
During the Fall of Reach, three Spartan-II's, John-117, Linda-058, and James-005 commandeered a Pelican to Reach Station Gamma. An ONI prowler, the Circumference, docked in the station having 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 Elite and Jackal rangers to secure the data. Eventually, John-117 was able to destroy the database but Linda-058 was killed (clinically) and James-005 was lost in the vacuum of space after his thruster pack suffered a malfunction from Covenant weapons-fire. Several marines were on-board the station: Sergeant Johnson, Privates Jenkins, Bisenti, and O'Brien. They were evacuated along with the Spartans.
During the battle, the station was severely damaged, with the station ring finally breaking into multiple pieces. However, a few fortified sections remained intact and fully pressurized. Near the end of the battle, a skirmish between a UNSC frigate and Covenant corvette took place within the vicinity of the station.
