The ZiS-3 was a Russian artillery piece used in both field artillery and anti-tank roles during World War II. It utilized the carriage from the 57-mm ZiS-2 and combined it with the 76.2-mm barrel of the Divisional Gun M1939. The pairing of such a large caliber gun with a relatively small carriage was made possible with the addition of a double-baffle muzzle brake. The ZiS-3 entered service in late 1942 and proved itself to be a reliable and capable light field gun that gained quick popularity with its users. Strong points of the ZiS-3 were its high rate of fire (about 25 rounds per minute) and that it was light and easily manhandled by its crew. The carriage featured a split rail and a shield to provide limited protection to its crew of five. Large numbers of ZiS-3 were captured by the Germans, who were all too happy to press them into their own service, redesignated as the 7.62cm Feldcanone 288R. It was nicknamed the "Ratsch-Bum" (crash-boom) by the Germans because of its distincitive sound when firing. The particular gun pictured here has changed ownership several times from the Russians to the Germans and finally to the Americans. This example of the ZiS-3 is believed to have been photographed in Metz, France in 1944.
