Mann's Marauders

In the last days of Earth, Mega-Corporations controlled the bulk of the planet, becoming governments unto themselves. After they depleted Earth's resources and destroyed the environment, the survivors had to abandon Earth. Then it was time to search out new planets to exploit. With little to no regard for the inhabitants, no one could stop the corporations from taking what they wanted.
Formed by survivors, cast-offs, and refugees of these planets to push back against corporate exploitation, Mann's Marauders was united under one banner by Dietrich Mann. This mercenary team began by fighting on land with troops and Grav-tanks, then grew to include starships and heavy fighters.
When corporations threaten your planet, you need Mann's Marauders.
