It is the approximate Russian equivalent of the NATO .50 BMG (12.7x99mm NATO) cartridge. The differences between the two are the bullet shape, the types of powder used, and that the casing of the 12.7x108mm is 9 mm longer. The 12.7x108mm can be used to engage a wide variety of targets, including armored vehicles, as proven in both Iraqi wars. An M1A2 tank was damaged by what the analysts believed was 12.7 mm fire from either a NSV or DShK machine gun at the gates of Baghdad International Airport on April 4 2003. In the Finnish Defence Forces, the NSV chambered in 12.7 x 108 is used primarily in an anti-aircraft role by all branches.
