The Voroshilovets is a World War 2 era tracked prime mover of Soviet origin. It was developed in the late 1930's as a more powerful alternative to the Komintern prime mover. The tracked chassis was very useful in the Russian climate with its mud in the summer and snow in the winter.

The chassis of the Voroshilovets is based on the T-24 tank. The chassis has two bogies with 4 roadwheels each. The Voroshilovets retains the rear drive sprocket but the engine is mounted in the large bonnet at the front. The cab seats three people. The rear of the vehicles makes up a load platform. This may seat the gun crew and allows for ammunition to be carried.

The Voroshilovets may tow artillery pieces and trailers up to 18 t. This allows it to tow the heaviest Soviet artillery pieces. The cargo platform holds up to 3 t of cargo or seats up to 16 people. The Voroshilovets was also used as recovery vehicle and was able to rescue medium and heavy tanks stuck in mud or snow.

The tracked chassis provides the Voroshilovets with good all terrain mobility. The road speed is rather limited at a maximum of 34 km/h. The mobility comes at the cost of a high fuel consumption.

The Voroshilovets was widely used by Soviet forces during World War 2. It was used to tow the heaviest Soviet artillery pieces. The Voroshilovets was used until the 1950's. By that time the need for prime moves was reduced due to lighter artillery pieces, more powerful trucks and self-propelled artillery.
