ODG Facility A-331 was one of the large Orbital Defense Generators that powered the Orbital Defense Stations in orbit around Reach. It was one of seven reactor complexes on Reach.


During the Fall of Reach, the facility was to be protected by the Spartan-II team arriving on Reach, but when the Covenant broke through the UNSC lines, the station was bombarded with heavy plasma. The Covenant compromised Complex Three, and the Spartans were last heard from when they fell back to Complex Seven. It is assumed that all the Spartans and Marines guarding this facility are dead.

Many of the marines were killed when Longsword bombers accidentally bombed the site due to an error. This also killed Lieutenant Buckman and Lieutenant Jake Chapman. When the Spartan Red Team came to the site, the Marines had won, but at horrible cost: only four Charlie Company Marines survived,[1] all of whom were terribly shell shocked.
