ANVIL Station

Anvil Station is a secret UNSC space station in orbit over an unknown planet. The Spartan-IVs and Swords of Sanghelios Sangheili warriors use the station to run War Games exercises in which they hone their combat skills and test experimental technology.

History
ANVIL Station serves as a testing ground and training station for Spartans and their associated MJOLNIR (GEN2), alongside cross-training Swords of Sanghelios units. The station has seen the oversight and testing of the following MJOLNIR suits;
 * COMPASS - Swords of Sanghelios artisan-armorers aboard the station produced experimental multi-band sensorary receptors for this suit.
 * DEADEYE - Tested on ANVIL Station in cross-training exercises with Sangheili Rangers.
 * DEMO - Tested on the station on behalf of an unidentified third party.
 * HIVEMIND - ANVIL Station was deemed the perfect testing ground for suits designed for Flood outbreak containment.
 * NAVIGATOR - Certain MJOLNIR Mark VII technologies have found their way into ANVIL Station testing armor.
 * PIONEER - Following its debut usage on Installation 03, Acheron Security hoped to use ANVIL to test out improvements to the PIONEER suit.
 * SOLDIER - This suit was tested on ANVIL and deemed one of the platform's most versatile variants.
 * SUTURE - Recently approved suit tested on ANVIL Station for use by Spartan medics.
 * TANKER - This suit was tested on ANVIL Station, and its resiliency was noted to impress even the Sangheili cohort.
 * WARRIOR - Despite being one of the platform's most mainline kits, WARRIOR was given testing in ANVIL's training courses.

Crew and complement
ANVIL Station is defended by dedicated squadrons of interceptors, with their pilots sporting the AVIATOR Mjolnir. The station has an additional internal security detail, with Spartans attached to these units noted to prefer the AIR ASSAULT armor.

Design
Built by the UNSC, Anvil Station was created for the Spartan-IV program for use in training human and Sangheili forces. The station consists of a large, cylindrical mid-structure featuring a command center on top. The structure is surrounded by two disk-shaped facilities, with the upper one consisting of several decks used for simulation training, and the lower one comprising of living quarters. At the lower end of the station are docking ports for transport modules. The station has a projected operational life of 250 years and in total there are 7365 humans and Sangheili working on-board.

History
On January 28th, 2552, the designs for the station were approved. As early as 2553, the ANVIL initiative saw a number of very select joint training engagements between Spartan-IVs and Swords of Sanghelios Sangheili.

On January 28th 2555, the station saw heavy use of experimental technology in use between Sangheili and Spartans.

Production notes
During development, ANVIL Station was referred to as "Crucible Station".

The Anvil Station was the setting for the cancelled Halo Online game. After the game's cancellation, both the station and the Anvil Initiative have been mentioned in ancillary media, such as Halo: Official Spartan Field Manual. With the arrival of Season 5 on Halo: The Master Chief Collection, the ANVIL Station was mentioned for the first time as the testing ground of several new armors added into Halo 3 ' s armor customization.
