It's a Gun... tank??
Ah yes the RX-75 Guntank. One of the three from the OG Squad of the first Gundam series together with the Grand Daddy RX-78-2 Gundam and the RX-77-2 Gun Cannon.
A half tank and a half mobile suit unit that provides long range artillery support fire.
Watch my video as I do a speed build and my thoughts on the GunTank.
