RX-75 Guntank

The RX-75 Guntank (ガンタンク, Gantanku?) is a fictional weapon from the mecha anime Mobile Suit Gundam. The real life Type 87 self-propelled anti-aircraft gun of the Japan Self-Defense Forces was unofficially nicknamed as Guntank after the fictional weapon by troopers.

The RX-75 Guntank was the first prototype mobile suit developed in the Earth Federation's Project V. However, the Guntank hardly qualified at all as a mobile suit, which generally referred to bipedal machines. The Guntank had the torso and arms of a mobile suit, but possessed a tank-like base with tracks. It also lacked the humanoid manipulator hands and had a canopy-style cockpit on the head, along with the cockpit in the torso. Like all Project V prototypes, the Guntank's design incorporate the Core Block System.

The RX-75 Guntank was developed when the first rumors of the Principality of Zeon's mobile suits reached the Federation. The Guntank was designed as a long-range anti-mobile suit and artillery support unit. Although its performance in this role fell below expectations, it did pack a heavy punch. Its main weapons were twin 180 mm recoilless cannons, which were capable of both effective direct and indirect fires at both long and medium ranges. The Guntank's two arms ended in four-barrel missile launchers instead of manipulator hands. These weapons provided good cover fire against enemy tanks and aircraft but less effective against enemy mobile suits at close range.

Guntank, along with Gundam has great cultural influence in Japan. The rescue robot T-52 Enryu (援竜) (official link of newer model T-53) created by Tmsuk(official page) for the Japanese fire department is quoted to be Guntank(?)'s huge rescue robot by My commu journal.
