The Marauder II was first built in 3012 in an attempt to take the firepower of the Marauder and combine it with the reliability and ruggedness of an assault chassis. The Marauder II carries as its primary weapons a pair of ER PPCs which give it a powerful long range punch. The ER PPCs are backed up by a LB-X Autocannon/10. Finally, for close range combat, the Marauder II carries two Medium Lasers. Finally, to make up for the reduced mobility of the Marauder II, the 'Mech was outfitted with jump jets that give it a jumping capability of up to ninety meters.
