Base HISS tank with custom designed and 3D printed turret with double mini gun barrels.
Tired of having his expensive HISS tanks eaten up by GI Joe's air superiority, Cobra Commander commissioned MARS to create an air defense version.
MARS engineers designed and built this one of kind double mini gun turret. Each side has six 50mm barrels capable of firing enough rounds to shred Joe's air forces.
HISS operators think it's more fun pointing these beauties down range at incoming ground vehicles.
