The three Space Marine heroes are the Force Commander, Apothecary, and Techmarine. These heroes specialties play off each other really well. The Force Commander is a melee specialist who charge into superior numbers of enemies, the Apothecary can support him and surrounding troops by healing, and the Techmarine can build turrets and teleporter relay beacons to keep re-supplying the armies in the forward lines. When the three heroes are working together, they can thrust into combat, keep their backbone strong, and prevent counterattacks.
