Songnam

Songnam is a city in the Kyonggi Province, of Korea on Earth. Due to its convenient location near Seoul, the South Korean capital, it is a largely residential city with a population similar to other satellite cities, such as Goyang and Gwacheon. Its most heavily occupied sector is the Bundang district, which is home to a huge number of multi-skyscraper apartment complexes that are also common in other major Korean cities. The Bundang district serves as Songnam's heart and provides the rest of the city with the Bundang subway line, which extends into Seoul.

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, with paintball, before it was delivered to Cairo Station.
