ZB-60
The ZB-60 was a heavy machine gun designed by Zbrojovka Brno in Czechoslovakia during the 1930s. Weapons acquired after the German occupation of Czechoslovakia in March 1939 were taken into Wehrmacht service as the 15 mm FlaMG 39(t); Former Yugoslav guns were designated as the 15 mm FlaMG 490(j). The Germans used them as light anti-aircraft guns during World War II. The British developed their 15 mm Besa Mk I from the ZB-60 for service on armored fighting vehicles.
