The Mars Front der Befreien (German for "Mars Liberation Front"), also referred to as the MFB, is one of four factions fighting for control of Mars. Sponsored by the Jupiter System Union, the objective of the MFB is to unify Mars and have it join the Union.
The MFB's commando unit, K Truppe, was one of the military units that participated in Operation Hagel to recapture Olympus Spaceport from the Neo-Third Reich Division a month before the Tenth Zenith of Things Tournament in ES 591.
