Special Warfare Center
From Halopedia, the Halo wiki
The Special Warfare Center, also known as Special Warfare Center Seongnam (or SWC) in Seongnam, Gyeonggi Province, United Korea, is a testing ground and training facility for the United Nations Space Command.
The SWC is one of the main MJOLNIR Powered Assault Armor testing facilities on Earth. There is a desert-like area with buildings and captured Covenant vehicles to give the training area a more realistic appearance. There is also a possibility that the armor itself was constructed there due to the fall of ONI facilities on Reach.
Maria-062 first tested the MJOLNIR Mark VI armor near at this location at the UNSC Operational Test and Evaluation Center, sparring against Echo and Kilo teams of the 340th ODST Combat Training Unit.
