The Sd.Kfz.251 was a German light half-track armoured personnel carrier. The Sd.Kfz.251 family of armoured personnel carriers was produced by Hanomag from 1938 to 1945, with over 15,000 vehicles of various modifications manufactured during this period. Initially, the Sd.Kfz.251 was intended for transporting infantry on the battlefield, but subsequently, many specialised vehicles were built on its chassis: from a standard armoured personnel carrier and command vehicle to rocket artillery systems and self-propelled artillery mounts.

One of many modifications of this APC was the Sd.Kfz.251/10, a self-propelled artillery mount armed with the 37 mm Pak 35/36 anti-tank gun. The self-propelled gun was used as a command vehicle and was intended to enhance the firepower of infantry units. Serial production ran from 1942 to 1943, during which period 311 were built. In 1944, due to the already insufficient firepower of the gun, all vehicles of the type were withdrawn from combat units and used in the rear areas.

Introduced in Update "Raining Fire" as a reward for the 2020 Wargame "Strategist" event, the Sd.Kfz.251 has the mobility and manoeuvrability of a medium tank, but lags behind most tracked vehicles in cross-country ability. The gun itself is located above the hull of the armoured personnel carrier, which allows it to fire while completely concealing the vehicle behind cover. The gun's power is sufficient for effective combat with enemy armour, and the fast reload rate allows for a fairly intensive rate of fire. However, the open fighting compartment and the crew, peering out from the hull up to their waist, make the vehicle very vulnerable even to machine gun fire.
