The RX-75 Guntank (or RX-75-4) is a heavy fire support mobile suit mecha from Mobile Suit Gundam. Unique for having caterpillar tracks as the main propulsion apparatus instead of legs.
In the compilation movie trilogy, the Guntank was decommissioned at Jaburo, resulting in it being replaced with a second Guncannon in its equivalent scenes in space.
It was designed by Ookawara Kunio.
