One of the few chapters made from the White Scars. You'd think that the White Scars were a part of the Drop Site Massacre or something, as that would give a reason for why we don't hear much about them or anyone relating to them. But no, this just another case of Games Workshop's laziness. You'd think that the parents of the Mantis Warriors would have been given some coverage. You'd think that the White Scars would be given more coverage too, right? Hell, they were even mentioned in IA:Vol 2. Not to mention that they were one of the featured Marine Chapters on the Tactical Squad box.
- Relief of Ferax Hive - Same place that a Eisenhorn novel took place in. But this time a corpse grinder cult uprising from the lawless underslumps sizes control of the hive. Having eaten everybody inside, the cannibals are driven insane by the hunger and spill outwards into the wastes, where they are subsequently destroyed by the massed guns of the Space Marines.
- Baran War - A three-way war between Orks, Biel-tan Eldar and several Marine Chapters. The Marauders participated in the initial reconquest of the sector from the hands of the greenskin menace.
- Orphean War - Imperium Vs Maynarkh Dynasty. The Marauders supplied an entire company to the efforts of Battlegroup Salvation.
