In 1982, this ammunition type was Barrett Firearms Manufacturing . first used in a sniper rifle , the M82A1 . The .50 BMG is used in the military sniper field as a cartridge with high destructive power and extreme range and is mainly used for targeted single shots against material targets such as radio systems and radar devices.
An additional type of ammunition independent of the standardized types is the Saboted Light Armor Penetrator (SLAP) cartridge, developed in the 1980s . Here a sub-caliber arrow-shaped penetrator made of tungsten carbide is fired by means of a plastic drive mirror. This type of ammunition is used to increase the combat value of the M2 machine gun . The penetration capacity is 19 mm armor steel at a distance of 1500 meters.
