Fireteam Osiris

Fireteam Osiris is a team of SPARTAN-IV supersoldiers of the Spartan branch.

History
After John-117 went AWOL along with his old SPARTAN-II unit, Blue Team, Jameson Locke recruited a team of SPARTAN-IV operatives with the task of recovering the Master Chief and Blue Team. The team was fitted with cutting-edge technology (including the Artemis Tracking System) to help them track down Blue Team.

During their quest to find Blue Team, Fireteam Osiris engaged the forces of Jul 'Mdama's Covenant faction on Kamchatka and participated in a joint mission with the Swords of Sanghelios in Sunaion.

Members

 * Jameson Locke
 * Holly Tanaka
 * Edward Buck
 * Olympia Vale

Production notes

 * Fireteam Osiris will be featured in Halo 5: Guardians. They will accompany Locke throughout the campaign and accept commands from the player. Buck, Tanaka, and Vale will also be playable in cooperative play, each with a specialized default loadout. The team will have access to the Artemis Tracking System which can highlight alternate routes as well as various items of interest.


 * Buck's place as the fourth member of Fireteam Osiris was filled by Gabriel Thorne in an early phase of the development of Halo 5: Guardians; Thorne was replaced by Buck later on after Nathan Fillion agreed to reprise his role. Thorne is still shown alongside the members of Osiris in an early piece of artwork featured as the cover of The Art of Halo 5: Guardians.

Trivia
Osiris was an Egyptian god of the afterlife, the underworld, and the dead.
