WW2 Italian self-propelled gun Semovente 90/53.
The Semovente M.41M da 90/53 is generally regarded as the most powerful of the available tank destroyers utilized by the Italian Army in World War II. Like other tank destroyer developments of the conflict, the Semovente 90/53 was born from wartime need and created by combining existing systems - either those proven or available in number. The weapon system entered operational service with the Italian Army in 1941 and only yielded a limited production run, build by FIAT, SPA and Ansaldo facilities.
