Reach Naval Officers Academy
From Halopedia, the Halo wiki
Reach Naval Academy was a facility on the surface of UNSC planet Reach and one of the best academies avaliable. It was responsible for the training of officers for various sections of the UNSC Navy, including ONI and Marine officers.
Between their intense physical training sessions, the Spartans were trained on the Reach Naval Academy grounds by the AI Deja from 2517 to 2525.
Lieutenant Wagner trained at Reach Naval Academy. He said it was the closest thing he had to a home in the outer colonies.
The campus of Reach Naval Academy was likely destroyed when the Covenant glassed the planet.
