In 3010, the Dragoons approached the Blackwell Corporation with the project of modifying the existing, highly successful 75-ton Marauder into a 100-ton assault 'Mech. The prototype Marauder II was completed in early 3012. House units and mercenary commands alike scrambled to get their hands on this powerful 'Mech, only to be rebuffed by Wolf's Dragoons, who had exclusive rights to the design. It took some three decades before the Dragoons allowed significant sales to outside units, and even then they carefully doled these 'Mechs out to only those units that met their discriminating criteria. This restriction ensured a demand for the 'Mech that constantly outstripped availability right up until the Word of Blake Jihad erupted.
         By that time, the Dragoons had revealed the existance of their Clan-tech Marauder IIs, but not their exact capabilities. The Word and their allies found out those capabilities the hard way, by facing them in battle first on Outreach and then throughout the Chaos March. The Marauder IIs helped to drive them back to Terra, and then followed them down to finish the Word off for good. Now, nearly a century after their introduction, the Marauder II still stands tall in the mercenary trade.

         Today's Marauder II is every bit as tough as the Dragoons' original design, but carries significantly more firepower and speed than its precursor. An extralight engine saves space for an impressive amount of StarSlab 300 armor and a devastating array of weapons. A Black Widow particle cannon and a Yellow Bird laser is carried in each arm and a Red Guard autocannon nestled in the torso gives it extra punch at medium and short ranges. An array of Geotec 300 jump jets in the legs give it the mobility to shock an opponent with the sight of such a large BattleMech in flight even now. They are most often used in rough terrain to achieve a tricky firing position that a 'Mech of its size would most often not be able to reach.

         The Marauder II C is an extremely expensive design, much more so than the Imp C, and as such is not used as much. Poorer mercenary units can rarely afford them, but in the richer members of the Allied Mercenary Command a Marauder II C is often a must have item. The Dragoons field the largest number of Marauder II Cs of any unit of course, but seeing them in other units has long since ceased to be rare.
