Maria-062 primes a mock grenade and hurls it at the ODST training unit.

Echo Four was a codename for an ODST stationed in Special Warfare Center in Seongnam on Earth during 2552, to help test the MJOLNIR Mark VI armor.

SPARTAN-062, the first SPARTAN-II to test the armor, was sent in training with several ODSTs. During the armor testing, SPARTAN-062 hurled a paintball grenade onto the middle of the unsuspecting ODSTs, neutralizing Echo 1 through 5. The sole survivor of the blast, Echo 6, makes a run for it and was quickly gunned down by 062, but not before initiating the "Bulgoki Gambit". After SPARTAN-062 was subdued and brought back to the Special Warfare Center, accompanied by Echo Four and his ODST companions.
