General Martin is the leader of a mercenary company known as Martin's Marauders, leading them personally in a siege tank. His forces are famous for their "Iron Golem" goliaths.
Martin's background is unknown, but at some point after the Brood War, he offered his services to the Terran Dominion to help deal with the New Trinidad Pirates.
