|Outcome||Initial stalemate, but joint Red Faction-Marauder victory in the second phase.|
The Marauder Conflict is the extended conflict between the Marauders and Earth Defence Force, Earth's military, during and prior to the Second Martian Revolution, though from certain perspectives this conflict could actually be viewed as part of the revolution, they could also be viewed as contemporaneous conflicts.Battle for Mariner Valley is long and bloody, but it is likely that the Marauders eventually prevail, pyrrhically. They push out the EDF into central Tharsis but themselves retreate deeper into the outskirts of Tharsis (The Irradiated Zone) likely because they could not sustain another battle as badly as the one in Mariner Valley.
The Marauder- EDF War becomes progressively more interlinked to the Second Martian Revolution as the Red Faction liberated Parker and moved Dust. By the end of the war, with the Red Faction-Marauder pact and the Battle of Mount Vogel among other things, the two conflicts had indisputably collided and merged.
- During the Battle of Mount Vogel, Vasha and a group of Marauders guarding the summit end of the accelerator at the top of the mountain are killed by EDF soldiers that landed on the mountain.
