(ЗиС-3)) (GRAU index: 52-P-354U) was a Soviet 76.2 mm divisional field gun used during World War II.

The addition of a muzzle brake reduced recoil and prevented damage to the light carriage upon firing.

Producing a ZiS-3 cost only a third of the time and two-thirds of the money of a F-22USV by making greater use of casting, stamping and welding.

Marshal Grigory Kulik, commander of Soviet artillery, had ordered a halt to the production of light 45 mm anti-tank guns and 76.2 mm divisional field guns in the belief that they were inadequate; the Soviets overestimated the armour protection of the latest German heavy tanks from propaganda about the Neubaufahrzeug multi-turreted prototype tank.

A subsequent demonstration impressed Joseph Stalin, who praised the weapon as "a masterpiece of artillery systems design."

Conveyor assembly lines admitted the use of low-skilled labour without significant quality loss.

Experienced laborers and engineers worked on complicated equipment and served as brigade leaders; they were replaced on the production line by young factory workers who were exempt from conscription, producing a new generation of skilled labourers and engineers.

The tactical characteristics of the 76.2-mm guns (M1939 and 1942) are their high rate of fire, good muzzle velocity, and great maneuverability.

Secondary missions are accompanying barrages and concentrations; neutralization of artillery and mortars; establishment of smoke screens; and destruction of wire.

The light carriage allowed the ZiS-3 to be towed by trucks, heavy jeeps, like American Lend-Lease-supplied Dodge WC-51/WC-52, simply called the 'Dodge 3/4'-tons by Soviet troops – or even manually hauled by the crew if required.

Unlike its predecessors, there exists no conversion to use the grenade cartridge of the 7,5 cm Pak 40 with a larger propellant charge to improve armor penetration capabilities.

[11] In 2016, the gun remained in active service with the armies of at least six sovereign nations: Cambodia, Nicaragua, Namibia, Sudan, Mozambique, and Tanzania.

[14] A number of other nations, including Russia[15] and Zimbabwe, retain functioning ZiS-3s to fire gun salutes during ceremonial occasions.
