When the Pandoran forces invaded Coyote and Mythos in December 2617, the MTG met them in a ground assault. They were vastly outnumbered, with many of their military bases around the planet falling to nuclear strikes within a few hours. The MTG were ultimately defeated by the invaders, and after helping to rescue Kelly Taylor and Enrique Todd, the remaining members of the force were wiped out when the Pandoran army nuked the planet.
