The 76-mm divisional gun M1939 (F-22 USV or USV) was a 76.2 mm cannon produced in the Soviet Union. It was adopted for Red Army service in 1939 and used extensively in World War II. The gun was designated as "divisional" - issued to batteries under the direct control of division headquarters. The F-22 USV was an intermediate model, coming between the F-22, which had limited anti-aircraft capability, and the simpler and cheaper ZiS-3, which eventually replaced it in production and service.
The USV had a split-trail carriage with suspension; metal wheels with rubber tires were borrowed from the ZiS-5 truck. The gun featured semi-automatic vertical sliding breech block and Bofors-type cradle; recoil mechanism consisted of hydraulic recoil buffer and hydro-pneumatic recuperator. Sights and elevation controls were located on different sides of the barrel. The chamber fitted the standard model 1900 cartridge, which meant that the gun could use ammunition manufactured for older 76.2 mm divisional and regimental guns.
