The HT-2 "Mad Cat" is Antaria's main heavy tank. It weighs 55 tonnes and is armed with an 80mm cannon and 2 machine guns. One mg is in a fixed, front-facing position, and the second is mounted on the roof and can be operated by the commander when looking outside of the hatch. It also has a parascope for the driver who operates the front machine gun to use. It has a 650-horsepower General Engineering HV134 engine and can has a max speed of 50km/h and a sustained road speed of 45-50km/h.
The MG model is from @juanandres123 (at least I think so)
