Operation: MARSH FLASH

Operation: MARSH FLASH was an operation of the United Nations Space Command in the former state of Arizona on Earth towards the end of the Human-Covenant War. The operation saw the tactical deployment of nuclear weapons against shielded Covenant positions centered around Free-fire Area OZONE. As a result, clusters of high-value Jiralhanae leadership were successfully eliminated.

The operation brought about the end of the UNSC's ongoing campaign in the region.
