Anvil Initiative

"An opportunity to train with Sangheili swordmasters? Sign me up."

- Spartan Gabriel Thorne

The Anvil Initiative is a cross-training and evaluation program of the UNSC Armed Forces' Spartan Operations, operated in collaboration with the Swords of Sanghelios. The Anvil Initiative provides Spartan-IVs an opportunity to directly interact and train with Sangheili warriors in both shared War Games and live exercises. Anvil also tests hybrid technologies developed by the Office of Naval Intelligence, corporate partners, Sangheili artisan-armorers, and special research collaborations.

The location of the Anvil Initiative and the details of its select participation are classified, and access is by invitation only.
