Operation: JOVIAN WHISTLE

"The bloody battle on the colony of Gao was an object lesson for the UNSC about the risks of dealing with independent colonies that harbored hatred towards the UEG."

- Curator on the battle

Operation: JOVIAN WHISTLE was an operation conducted by the UNSC on the human colony of Gao in order to retrive Forerunner technology on the planet.

Prelude
In 2553, a UNSC research battalion escorted by the Spartans of Blue Team arrived on the planet Gao investigating recent occurrences of therapeutic effects and miraculous cures found inside a vast cavern system on the planet. The research battalion's arrival was followed by several brutal murders of Gao natives in the caverns, prompting the Gao Ministry of Protection to dispatch Special Inspector Veta Lopis and her field team to investigate. However, the situation escalated into an all-out crisis when Insurrectionist sympathizers within Gao's government sought to take control of Forerunner artifacts located on the planet and allied with the militant cult Keepers of the One Freedom to accomplish their goals.
