'''Operation: JOVIAN WHISTLE'''{{Ref/Game|Id=H5GLtd|Halo 5: Guardians Limited Edition|[[Halo 5: Guardians Limited Edition dossiers#Kelly-087|Dossier files]] - Kelly-087}} was an operation conducted by the [[United Nations Space Command|UNSC]] in [[2553]] on the colony of [[Gao]] in order to retrieve [[Forerunner]] technology.<ref name="hll">'''Halo: Last Light''', ''description''</ref>

==Prelude==
In 2553, the UNSC's [[717th Xeno-Materials Exploitation Battalion]], escorted by the [[Spartan]]s of [[Blue Team]], arrived on the planet  Gao to investigate a transmission believed to have originated from a Forerunner [[ancilla]] on the planet. Following the transmission, there had also been reports of miraculous cures found inside the planet's vast [[Montero Cave System]]. 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, headed by would-be president [[Arlo Casille]], decided to eliminate the UNSC forces and take control of the ancilla. They allied themselves with the militant cult [[Keepers of the One Freedom]] and smuggled them on Gao, seeking to use the Keepers as a proxy force through which to accomplish their goals without attacking the UNSC directly.{{Ref/Reuse|hll}}

The UNSC presence in the village of [[Wendosa]] included the 717th's Charlie Company, comprising of 150 heavy infantry marines armed with heavy machine guns, [[LAU-65D/SGM-151 missile pod|missile pods]], [[M6 Spartan Laser|nonlinear lasers]] and [[M41 SPNKR|rocket]] and [[M319 grenade launcher|grenade]] launchers. The sole road into the village was blockaded by two [[M12 Warthog]]s armed with [[M41 Extended Light Anti-Aircraft Gun|M41 anti-aircraft guns]] and the area surrounding the village was mined and trapped, with a series of motion sensors strung up around the perimeter, turning the village into a veritable fortress.<ref name="LL11">'''Halo: Last Light''', ''chapter 11''</ref>

==The Operation==
Blue team was tasked with escorting the GMoP investigation teams to the crime scenes by [[Major]] [[Ira Halal]], where they started collecting evidence and deployed [[Trace evidence bot|Spiders]]. Veta Lopis initially suspected Fred and the other Spartan-IIs due to the nature of the brutal murders. While the team was investigating crime scene charlie, Major Halal went to document another body found at Bivouac Site Tango under Wendosa. Fred and Lopis later returned back to the [[Montero Vitality Center]] on the surface.
Meanwhile, Intrepid eye and the Huragok [[Roams Alone]] came across a scouting party of marines and the ancilla had to kill Private Hayes by electrocution as he had spotted her, he managed to get a few shots on intrepid and the huragok, resulting in Roams Alone losing his buoyant gases, when Major Halal came to investigate, he was dragged for a little distance by the ancilla then killed when she got his tacpad containing a fragment of Wendell, with whom she conversed and inquired about the status of [[Shaps III|Wuatera Thresis]], and learned that it had been glassed by the [[Pious Inquisitor]].
