Comparing: ISU-122S vs. Sturer Emil

A heavy assault gun, built on the basis of the IS tank, was effective against German heavy tanks as well as fortifications. The prototype was built at the Chelyabinsk Kirov Plant in April 1944. The vehicle entered service in August of that year, and a total of 675 vehicles were manufactured in 1944 and 1945.

Experimental tank destroyer developed on the basis of the VK 30.01(H) heavy tank. Only two vehicles were manufactured. They fought on the Eastern Front. The tank destroyer was designated as “Sturer Emil” (German for “Stubborn Emil”) due to frequent breakdowns.
