HIGHCOM Armory Omega
From Halopedia, the Halo wiki
Summary
Reach has many weapon caches placed by HIGHCOM for times of emergency. Armory Omega is one of such caches. It contained special weapons created by ONI, such as the Nova, as well as many standard infantry weapons and vehicles. This cache was found by the SPARTAN Red Team during the beginning of their defense of Reach's Orbital Super MAC Guns generators. It is unknown what happened to the cache's supply of weapons, minus the Nova, after the glassing of Reach.
