S-480 "Killdozer" Heavy Tank

This staple heavy tank of the UOAF was armed with a heavy-duty rail cannon, where each shell could apply massive damage to the enemy. It carried considerably more armor and firepower than the S-440 Medium Tank, making it an excellent choice against ground units and motherships. The tradeoff in carrying all of this armor is slower movement, which made the S-480 vulnerable to air attacks. But again, it is well served by its heavy armor, despite a quad-petrochemical drive train.
