Type-1 Cho-Ro super heavy tank

The Type-1 Cho-Ro (1式) was a Yamataian designed for the Yamatai Imperial Army and used during the Second Escar-Varunan War. Developed from the preceding Type-47 Cho-I experimental super heavy tank, the Cho-Ro was designed to defeat the Chiseian defences along the Yenokaji Line, which had defeated Yamataian forces during the First Escar-Varunan War. 150 Cho-Ro were produced, and the chassis served as the basis for further super-heavy tank developments in Yamatai.

However, the tanks were largely ineffective on the battlefield due to its large size and weight, low speed, and constant mechanical problems. Towards the end of the war, most of the remaining tanks were converted into stationary bunkers during the defence of Hinomoto. After the war ended, all of the surviving Cho-Ro were scrapped except for one, which had been captured by Chisei during the war. In 1986, Chisei returned the tank to Yamatai, and it is currently preserved in the Kawazaki National Tank Museum at Kawazaki.
