Reach FLEETCOM Military Complex (Earth-5875)

"This place will become your home, your fellow trainees will be your family now. The training will be difficult. There will be a great deal of hardship on the road ahead, but I know you will all make it."

- - Dr. Catherine Halsey

The Reach FLEETCOM Military Complex was a military base of the UNSC, at the Highland Mountains, on Reach, which was also home to Castle Base, Camp Hathcock, and the Military Reservation 01478-B. It housed the Reach Naval Officers Academy and served as the main facility of the SPARTAN-II Program through its duration.

History
On September 23, 2517, 74 children kidnaped for the SPARTAN-II Program were brought to a secure amphitheater within the complex, where they proceeded to be conscripted into the program by its creator, Dr. Catherine Halsey, as per Naval Code 45812. They were then escorted to their barracks, where they ate, drank and went to sleep. The next day, all of the SPARTAN children were awoken by Chief Petty Officer Franklin Mandez, who led them to the Reach Naval Officers Academy, where they met with the Auton synthetic Déjà to study.

On November 2nd, 2525, Vice Admiral Michael Stanforth gave the first briefing to all SPARTAN-IIs at the Reach Naval Officers Academy, on Reach, showing them video recording of the fall of Shanxi, alongside schematics and diagrams of unggoy and kig-yar soldiers and a cryptic word uttered by the leaders of the alien attackers "Your destruction is the will of the Gods, and we are their instrument". There, he revealed that the training for the SPARTAN-IIs would need to be accelerated to succeed in combating the Covenant, including the early issuing of the MJOLNIR Powered Assault Armor. For the next years during the First Contact War, Michael exerted complete control over the ground and orbital operation of the SPARTAN-IIs.

Following the recovery of the SPARTAN-IIs from their augmentations at Medical Facility Endurance, in 2525, they were unable to be further trained in the complex because of a series of physical complications. After their first day back in the base, three trainers of the program were killed by the teenagers in accident during hand-to-hand combat operations. The SPARTANs were then sent to an abandoned titanium mine at the Highland Mountains, where their trainers were given Mark I MJOLNIR to defend themselves from the strength of the supersoldiers.

On August 27th, 2552, all surviving SPARTAN-IIs were gathered at the complex's amphitheater for a final directive: to acquire a Covenant ship, infiltrate the Covenant capital and return one of their Hierarchs to force a truce between the UNSC and the Covenant, bringing an end to the First Contact War.
