   Summary

   Deep within ONI section 3 is a select group of Spartan IIIs, recently upgraded to IVs, still operating from the shadows.
   Fireteam Chaos.
   And a new mission has arrived,
   Head to Reach, back to the old ONI Sword Base, and recover some...
   sensitive data.
   The only problem?
   They now have to work with the Sangheili.
   Oh, and they're led by a man who is, at his best? a trigger-happy, hyper-lethal, Commando with zero regard for the term "unnecessary risk". and at worst is a Schizophrenic asshole who could make picking up groceries into a crisis.
