The 3,7 cm KPÚV vz. 34 (Czech: kanón proti útočné vozbě) (designated 3,7 cm PaK 34(t) in German service) was an anti-tank gun produced by the Škoda Works in Czechoslovakia. Škoda's own designation for it was A3. It is not known if guns seized by Germany after the occupation of Bohemia-Moravia saw service in World War II. Slovakia acquired 113 when it declared independence from Czechoslovakia in March 1939.
It was designed to a Czech Army requirement to penetrate 30 mm (1.2 in) of armor at 1,000 m (1,100 yd) in 1934. It also fired a HE shell out to a maximum range of 4,000 m (4,400 yd). The gun had a small shield and wooden-spoked wheels, although some were fitted with pneumatic wheels.
