MJOLNIR
In 2552, SPARTAN-117's new MJOLNIR Mark VI armor was shipped to Cairo Station from the Special Warfare Center near Songnam. Is it is a possibility that the new armor was constructed there, due to the fall of the ONI facilities on Reach. SPARTAN-062 tested the Mark VI's armor against a squad of ODSTs in Songnam before it was delivered to Cairo Station.[1]
