Small Arms and Light Weapons also include ammunition, explosives, hand grenades, land mines and any other man portable weapons not listed above. In contrast, the term "heavy weapons" generally refers to any other weapon systems that are too cumbersome for foot transportation and hence have to rely on fixed mounting platforms installed upon wheeled frames/vehicles, vessels, aircraft or fortifications for effective operation.
Definition by international legal conventions
According to the United Nations Office on Drugs and Crime, the international framework on firearms is composed of three main instruments: the Firearms Protocol, the United Nations Programme of Action to Prevent, Combat and Eradicate the Illicit Trade in Small Arms and Light Weapons in All Its Aspects and the International Instrument to Enable States to Identify and Trace, in a Timely and Reliable Manner, Illicit Small Arms and Light Weapons, where only the Firearms Protocol is legally binding. The ITI, adopted by the United Nations General Assembly on 8 December 2005, defines small arms and light weapons as: Such arms control policies and treaties are focused on international arms trafficking, and in the standardization of laws, protocols and sharing of law enforcement information and best practices across nations to prevent illicit arms sales. They also focus on terrorism, arms proliferation as a humanitarian concern, disarmament in the face of extreme violence, and cases of ameliorating anarchy, civil war and international conflict. SALW provisions are generally not oriented towards imposing or enforcing domestic national or local legislation of legitimate gun ownership or sale.
UN SALW control efforts
and light weapons are used in conflicts around the world, causing injury and death. Small arms control was first broached by UN Resolution A/RES/46/36, which was expanded upon by A/RES/50/70. This latter resolution mandated a panel of experts to research the type of small arms and light weapons being used in the world's conflicts and to study which weapons might apply to fall under an arms control regime. The recommendations of expert reports returned to the General Assembly, A/52/298 and A/54/258 led to a July 2001United Nations Conference on the Illicit Trade in Small Arms, with a follow-up in July 2006. On 26 September 2013 the UN Security Council passed Resolution 2117, which urged nations to remain committed to small arms embargoes and SALW control protocols. Work on SALW via the United Nations is coordinated by the Office for Disarmament Affairs, though the UN Coordinating Action on Small Arms mechanism, which comprises 21 UN departments and agencies working on different aspects of small arms and light weapons control. The United Nations Institute for Disarmament Research, carries out research in arms control affairs and has published many articles and books related to small arms and light weapons. On 2 April 2013, the UN General Assembly voted overwhelmingly to adopt the Arms Trade Treaty to govern the legal international trade in many types of conventional weapons, from warships and aircraft to small arms and light weapons. A basic obligation of the treaty is that all States Parties should establish or maintain controls in the area. In this way, the treaty also helps the international community to address unregulated or illegal trade in conventional weapons. The treaty opened for signature on 3 June 2013. To date, two-thirds of UN member states have signed the treaty, and 72 have ratified it. The treaty entered into force on December 24, 2014.
In 2018, Small Arms Survey reported that there are over one billion small arms distributed globally, of which 857 million are in civilian hands. U.S. civilians alone account for 393 million of the worldwide total of civilian held firearms. This amounts to "120.5 firearms for every 100 residents." The worlds armed forces control about 133 million of the global total of small arms, of which over 43 percent belonging to two countries the Russian Federation and China. Law enforcement agencies control about 23 million of the global total of small arms.
