Echo Team (Earth-5875)

Echo Team was a UNSC Marine Corps ODST unit which providee realistic, real-time combat training exercises for the UNSC Special Forces, at the Special Warfare Center, in Seongnam, Gyeonggi Province, on Korea, Earth.

History
In October 2552, Echo Team, alongside Kilo Team provided combat exercise for the MJOLNIR Powered Assault Armor/Mark VI, in Seongnam. There, SPARTAN-II Maria-062 used the armor, and was deployed from low orbit at Earth with parafoil, where she launched a covert attack against the ODSTs.

Almost immediatly, she neutralized six of the trainers with paint pellet guns and physical moves. When she entered in the nearby structure, she was subdued by Kilo Team, who were covering and waiting for her.

The armor was later sent to her fellow SPARTAN-II John-117 at Cairo Station, minutes before the beginning of the Covenant's invasion and the Battle of Earth.
