Question: What year did the country that today uses the Zastava M76 sniper rifle gain independence as a nation? Passage:During World War II it was one of the few cartridges used by both the Axis and Allied powers, a distinction it shared with the 9×19mm Parabellum pistol round. Apart from being the standard rifle cartridge of the German and Polish armed forces, it was also used by the armed forces of Great Britain in the Besa machine gun, which was mounted in some of their tanks and other armoured vehicles, as well as being extensively used by the Chinese, especially early in the war. After World War II it was used by the early Bundeswehr of West Germany. Later, when Egypt decided to manufacture the Hakim rifle, a licensed copy of the Swedish Ag m/42, they redesigned the breech to accept the 7.92×57mm Mauser cartridge rather than use the original 6.5×55mm Ag m/42 cartridge. Its military use continues today (2012) in the former Yugoslavia in the Zastava M76 sniper rifle and the license-built copy of the MG 42, the M53 Šarac machine gun.
