The 12.7×108mm cartridge is a 12.7 mm heavy machine gun and anti-materiel rifle cartridge used by the former Soviet Union and Warsaw Pact countries, as well as China, Iran, and North Korea. It was invented in 1934 to create a cartridge like the German 13.2mm TuF anti-tank rifle round and the American .50 Browning Machine Gun round (12.7×99mm NATO).
It is used in the same roles as the NATO .50 BMG (12.7×99mm NATO) cartridge. The two differ in bullet shape and weight; the casing of the 12.7 × 108 mm is slightly longer, and its larger case capacity allows it to hold slightly more of a different type of powder. The 12.7 × 108 mm can be used to engage a wide variety of targets on the battlefield, and will destroy unarmored vehicles, penetrate lightly armored vehicles, and damage external ancillary equipment (e.g. searchlights, radar, transmitters, vision blocks, and engine compartment covers) on heavily armored vehicles, such as tanks.Technical Intelligence Bulletins May - June 2003 https://web.archive.org/web/20060813023341/http://www.wlhoward.com/id554.htm#prof August 13, 2006 It will also ignite gasoline and—since 2019—diesel fuel (experimental "Avers" AP/I round).ЦАМТО / Новости / В России создали новые зажигательные патроны калибра 12,7 мм Russia has created new incendiary cartridges of 12.7 mm caliber ru https://armstrade.org/includes/periodics/news/2019/0301/115051260/detail.shtml 2021-05-07 armstrade.orgRU patent 2655338C1 CARTRIDGE WITH ARMOR-PIERCING INCENDIARY BULLET TsNIITochMash 2018-05-25
