Order of battle (Viery, Reach)

"We are now under attack across the Viery territory, including orbital defenses. As per the Winter Contingency, we are countering on every front."

- Auntie Dot

During the Fall of Reach, the order of battle for operations in the Viery Territory on Reach comprised many units from the UNSC Army and Marine Corps. Air support was provided by Navy warships and A/X craft, while airlift came from the Air Force. Over the course of the battle, three Army brigades and numerous Marine rifle and shock infantry battalions would both defend against and counterattack the Covenant in Viery. Elements of this joint force participated in the Battle at Szurdok Ridge, where they attempted to prevent the Covenant from gaining a foothold on Reach. Based on the organizational structure of the units involved, approximately 6,700 soldiers and an equal or greater number of Marines were deployed across the theater.
