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 participated in a joint mission with the Swords of Sanghelios against a Covenant faction.
