Technical and Historical Notes

 

In UC 0065, the Earth Federation Forces roll out the RTX-65 Guntank Early Type as a new MBT (main battle tank). The RTX-65 is more advanced than the Type 61 MBT and fuses a humanoid torso with a tank body. However, over the course of the next decade, the EFF falls behind the Principality of Zeon in mobile suit research and scrambles to catch up. In UC 0075, the EFF develops the experimental RTX-44, which becomes the basis of the RX-75-4 Guntank. The RX-75-4 includes several improvements over its predecessor, such as the Core Block System, which houses the FF-X7 Core Fighter in the torso to serve as an escape craft for the primary pilot. If the Guntank's top half is ejected to release the Core Fighter, it can continue to function as a stationary gun emplacement. Like the earlier RTX-65, the Guntank has two pilots: a driver in the torso, and a gunner in the head. The Guntank's armaments include two 180mm cannons mounted on its shoulders, plus a pair of quadruple missile launchers mounted as its arms.

On September 18, UC 0079, the Zeon ace pilot Char Aznable attacks the Side 7 space colony where Operation V mobile suits are secretly under development. A surviving Guntank is transferred to the assault carrier White Base, along with the RX-77-2 Guncannon and RX-78-2 Gundam. As the White Base travels across Earth, the Guntank is modified to allow the primary pilot to serve as both driver and gunner in the head-based cockpit. The Guntank performs well enough for the EFF to produce the RX-75 Guntank Mass Production Type, which is deployed to Southeast Asia and other fronts. The variant RTX-440 Assault Guntank sees combat in Europe during Operation Odessa. A troop-carrying variant is also deployed during Operation Star One and is part of the invasion of the space fortress A Baoa Qu. After the One Year War, the EFF rolls out the RMV-1 Guntank II, which sees use for several decades. The Guntank also inspires the design of the later D-50C Loto, which can transform from a tank into a mobile suit form.
