Amid the severe shortage of resources and fuel, the GH-800 amphibious tank is virtually the one and only of heavies still in use. All attempts to build more heavily armored ship failed, because such ships required to expend considerable supplies for building and high amount of oil for their maintenance.

GH-800 (also called a Hammerhead) has proved itself to be a perfect balance of moderate running expenses and impressive firepower. Twin-barrel guns of large caliber blast through any armor. However, in battle it was mostly effective against slow or non-moving targets. To compensate for that, Hammerhead firearms were upgraded to include an additional machine gun. It makes the ship all geared up to take attacks of aircrafts or Piranhas. Nonetheless, Hammerhead still remains a sitting duck for enemy aviation.
