T-4B Bunkerbuster The first of the T-4B variants, the Bunkerbuster fires a devastating HE shell that obliterates buildings and fortifications. Just as heavily armored as the regular T-4B but the high reload time make it vulnerable against larger enemy concentrations. Just like the AT rocket troopers, this tank has an auto fire that can be disabled in order to manually shoot instead. custom turret made by 1138 aka Yyhrs
