The .50 Browning Machine Gun is a .50 in (12.7 mm) caliber cartridge developed for the M2 Browning machine gun in the late 1910s, entering official service in 1921. Under STANAG 4383, it is a standard service cartridge for NATO forces as well as many non-NATO countries. The cartridge itself has been made in many variants: multiple generations of regular ball, tracer, armor-piercing (AP), incendiary, and saboted sub-caliber rounds. The rounds intended for machine guns are made into a continuous belt using metallic links.
An anti-personnel weapon is a weapon primarily used to maim or kill infantry and other personnel not behind armor, as opposed to attacking structures or vehicles, or hunting game. The development of defensive fortification and combat vehicles gave rise to weapons designed specifically to attack them, and thus a need to distinguish between those systems and ones intended to attack people. For instance, an anti-personnel landmine will explode into small and sharp splinters that tear flesh but have little effect on metal surfaces, while anti-tank mines have considerably different design, using much more explosive power to effect damage to armored fighting vehicles, or use explosively formed penetrators to punch through armor plating.
An anti-materiel rifle (AMR) is a rifle designed for use against military equipment (materiel), rather than against humans ("anti-personnel").
Barrett Firearms Manufacturing is an American manufacturer of firearms and ammunition located in the unincorporated town of Christiana, Tennessee. It was founded in 1982 by Ronnie G. Barrett for the single purpose of building semi-automatic rifles chambered for the powerful .50 BMG ammunition, originally developed for and used in M2 Browning machine guns. Barrett began his work in the early 1980s and the first working rifles were available in 1982, hence the designation M82. Barrett designed every single part of the weapon personally and then went on to market the weapon and mass-produce it out of his own pocket. He continued to develop his rifle through the 1980s, and developed the improved M82A1 rifle by 1986.

The RT-20 is a Croatian anti-materiel precision rifle developed by Metallic in Rijeka in the mid-1990s and marketed by RH-Alan. It was developed to shoot the thermal sights on Serbian M-84 and T-72 tanks. The name itself is actually an acronym of the Croatian word Ručni Top 20, or "Handheld Cannon 20mm". Operating with a bolt action, it houses a single 20mm round and must be reloaded after each shot. Given its large caliber, it is one of the most powerful anti-materiel rifles currently in use by any country and is comparable to the South African Denel NTW-20 and the Indian Vidhwansak, with the difference being that the RT-20 is recoilless.
