Mark VI MJOLNIR armor test
On the morning of October 20, 2552, Kilo and Echo teams of the 340th CTU provided a mock combat exercise to test a suit of Mark VI MJOLNIR armor in Seongnam. SPARTAN Maria-062, who wore the armor, deployed from low Earth orbit via a parafoil and launched a sudden attack on the ODSTs. She was able to neutralize six ODST trainers with paint pellet guns, paint grenades, and hand-to-hand combat. However, as she entered structure Alpha-Two, she was quickly subdued by another group of ODSTS. Later that day, the armor was delivered to Master Chief Petty Officer John-117 only minutes before the Covenant's invasion of Earth.

Equipment
During exercises, the members of the 340th Combat Training Unit utilize paint pellet guns, paint grenades, and "Humbler" stun devices. They likely also utilize tactical training rounds and perhaps the derivative tactical training claymores. During exercises, members of the 340th CTU wear standard ODST battle armor, which provides full protection to the body and face.
