The ZIS-6 (Russian: ЗиС-6) is a Soviet general purpose 6×4 army cargo truck, a three-axle version of the ZIS-5 two-axle truck. It was built from 1933 until October 1941 at the Moscow Zavod imeni Stalina factory and reached a total production of 21,239.
A reliable truck, it served as a base for the creation of a number of specialized military modifications- searchlight truck, radio and radio repair station, mobile field workshop, supply delivering vehicle, troops moving vehicle, artillery towing vehicle. But is best known for its role as the first multiple rocket launcher in July 1941. It was built by the "Compressor" Plant's Design Office during World War II (1941–45). Very few ZIS-6 trucks survive till today.
ZIS-6 appears on some levels as a decoration, but the most notable role was on the "Climbing Mamayev Hill" level, where 4 such trucks were in the role of a rocket launcher.
- The front of the truck is slightly thicker than in reality.
