  A firearm is a barreled ranged weapon that inflicts damage on targets by launching one or more projectiles driven by rapidly expanding high-pressure gas produced by exothermic combustion (deflagration) of a chemical propellant, historically black powder, now smokeless powder.
  
  In the military, firearms are categorized into heavy and light weapons regarding their portability by infantry. Light firearms are those that can be readily carried by individual foot soldier, though they might still require more than one individual (crew-served) to achieve optimal operational capacity. Heavy firearms are those that are too large and heavy to be transported on foot, or too unstable against recoil, and thus require the support of a weapons platform (e.g. a fixed mount, wheeled carriage, vehicle, aircraft or water vessel) to be tactically mobile or useful.
  
  The subset of light firearms that only use kinetic projectiles and are compact enough to be operated to full capacity by a single infantryman (individual-served) are also referred to as small arms. Such firearms include handguns such as pistols, revolvers, and derringers; and long guns such as rifles (and their subtypes), shotguns, submachine guns, and machine guns.
  
  Among the world's arms manufacturers, the top firearms manufacturers are Browning, Remington, Colt, Ruger, Smith & Wesson, Savage, Mossberg (United States), Heckler & Koch, SIG Sauer, Walther (Germany), ČZUB (Czech Republic), Glock, Steyr Arms (Austria), FN Herstal (Belgium), Beretta (Italy), Norinco (China), Rostec, and Kalashnikov (Russia). Former top producers included the Springfield Armory (United States), the Royal Small Arms Factory (United Kingdom), Mauser (Germany), Steyr-Daimler-Puch (Austria), and Rock Island Armory under Armscor (Philippines).
  
  As of 2018 the Small Arms Survey reported that there were over one billion firearms distributed globally, of which 857 million (about 85 percent) were in civilian hands. U.S. civilians alone account for 393 million (about 46 percent) of the worldwide total of civilian-held firearms. This amounts to "120.5 firearms for every 100 residents". The world's armed forces control about 133 million (about 13 percent) of the global total of small arms, of which over 43 percent belong to two countries: the Russian Federation (30.3 million) and China (27.5 million). Law enforcement agencies control about 23 million (about 2 percent) of the global total of small arms.
