All of the Marauder variants can mount a HGR. But unlike the other non-hero variants, the MAD-5M can rock five medium pulse lasers as secondary weapons. Also this appears to be the first HGR marauder build posted on Mechspecs... If I had the hero variant I would probably do something similar with it, only with ERMLs and a faster engine. But I don't, so this is the next best thing.
