Free-fire area OZONE

Free-Fire Area OZONE was a location designated by the UNSC in Arizona, United Republic of North America.

History
During the Battle for Earth, from November 10 to December 3, 2552, Covenant forces excavated and occupied built-up positions at this location. On November 19, the UNSC deployed nuclear weapons against multiple shielded enemy positions at OZONE. Two weeks later, Fleet Admiral Joseph Harper directed Operation: MARSH FLASH, which successfully eliminated clusters of high-value Jiralhanae attempting to activate an artifact in this area.
