The 76-mm divisional gun M1942 (ZiS-3) was a Soviet 76.2 mm divisional field gun used during World War II. ZiS was a factory designation and stood for Zavod imeni Stalina ("factory named after Stalin"), the honorific title of Artillery Factory No. 92, which first constructed this gun. Soviet soldiers liked ZiS-3 guns for their extreme reliability, durability, and accuracy. It was easy to maintain these guns and train novice crews with them. Light carriage allowed the ZiS-3 to be towed by trucks and heavy jeeps (such as the American lend-leased Dodge 3/4) or even hauled by the crew. ZiS-3 had good anti-armour capabilities, it could knock out any German light and medium tank with its armour-piercing round. The appearance of the Tiger I and later the Panther, however, made the lives of ZiS-3 crews much harder, for their frontal armour was immune except for some small ballistic windows. A battery of ZiS-3 consisted of four guns, with three batteries combined into a division, or battalion. Independent anti-tank regiments consisted of six batteries with no divisions. In addition to the gun batteries there was a staff battery which included a fire control section.
