The RTX-440 Ground Assault Type Guntank

The RTX-440 Assault Guntank was a mobile suit based on the prototype RTX-44. However, its development was halted after technical officer Clyde Bettany stole its specs and defected to Zeon, placing his subordinate and lover Aline Nazon under suspicion. Compared to the RX-75-4 Guntank, the Assault Guntank could deploy its secondary caterpillar treads and have its torso squat for its assault mode, which allowed it to move at higher speed. The Assault Guntank featured more armaments than the standard Guntank, including its main 220mm cannon, bob guns, a flamethrower, heavy mines, 2-tube MLRS and a rocket launcher.
