Description from the publisher: Steel Guards are some of the most formidable fighters on the planet. Their half-robotic bodies makes them very hard to kill, allowing them to gain incredible combat experience. The Anti-Infantry squad of the Steel Guard is one of the most feared combat unit on the planet. Nobody ever faced them that wasn't changed by the experience. The thermobaric grenade they fire melts flesh, bone and steel alike. Nothing known to man can survive the explosion.
