NSV

The NSV is a Russian machine-gun produced since the 1970s, first as a commander's guns for mounting on tanks, then as a heavy support weapon for infantry, and then as a tank mounted anti-aircraft weapon. The NSV is chambered for the 12.7 mm Soviet cartridge which it takes from a belt feed and fires at a rate of 750 rounds per minute. The NSV is also used by the Finnish army.
