The terms conventional weapons or conventional arms generally refer to weapons whose ability to damage comes from kinetic, incendiary, or explosive energy and exclude weapons of mass destruction (e.g., nuclear, biological, radiological, and chemical weapons [1] ).
Conventional weapons include small arms, defensive shields, light weapons, sea and land mines, as well as bombs, shells, rockets, missiles, and cluster munitions. [2] These weapons use explosive material based on chemical energy, as opposed to nuclear energy in nuclear weapons. [2] [3] Conventional weapons are also contrasted with weapons of mass destruction and improvised weapons.
The Geneva Conventions govern the acceptable use of conventional weapons in war time. Conventional weapons are also regulated or prohibited under the United Nations Convention on Certain Conventional Weapons. Others are prohibited under the Convention on Cluster Munitions, the Ottawa Treaty (also known as the Mine Ban Treaty), and Arms Trade Treaty.
A land mine, or landmine, is an explosive weapon concealed under or camouflaged on the ground, and designed to destroy or disable enemy targets, ranging from combatants to vehicles and tanks, as they pass over or near it.
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission or a combination of fission and fusion reactions, producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter.
Arms control is a term for international restrictions upon the development, production, stockpiling, proliferation and usage of small arms, conventional weapons, and weapons of mass destruction. Historically, arms control may apply to melee weapons before the invention of firearm. Arms control is typically exercised through the use of diplomacy which seeks to impose such limitations upon consenting participants through international treaties and agreements, although it may also comprise efforts by a nation or group of nations to enforce limitations upon a non-consenting country.
Chemical warfare (CW) involves using the toxic properties of chemical substances as weapons. This type of warfare is distinct from nuclear warfare, biological warfare and radiological warfare, which together make up CBRN, the military acronym for chemical, biological, radiological, and nuclear, all of which are considered "weapons of mass destruction" (WMDs), a term that contrasts with conventional weapons.
The Chemical Weapons Convention (CWC), officially the Convention on the Prohibition of the Development, Production, Stockpiling and Use of Chemical Weapons and on their Destruction, is an arms control treaty administered by the Organisation for the Prohibition of Chemical Weapons (OPCW), an intergovernmental organization based in The Hague, The Netherlands. The treaty entered into force on 29 April 1997. It prohibits the use of chemical weapons, and also prohibits large-scale development, production, stockpiling, or transfer of chemical weapons or their precursors, except for very limited purposes. The main obligation of member states under the convention is to effect this prohibition, as well as the destruction of all current chemical weapons. All destruction activities must take place under OPCW verification.
A weapon of mass destruction (WMD) is a biological, chemical, radiological, nuclear, or any other weapon that can kill or significantly harm many people or cause great damage to artificial structures, natural structures, or the biosphere. The scope and usage of the term has evolved and been disputed, often signifying more politically than technically. Originally coined in reference to aerial bombing with chemical explosives during World War II, it has later come to refer to large-scale weaponry of warfare-related technologies, such as biological, chemical, radiological, or nuclear warfare.
A cluster munition is a form of air-dropped or ground-launched explosive weapon that releases or ejects smaller submunitions. Commonly, this is a cluster bomb that ejects explosive bomblets that are designed to kill personnel and destroy vehicles. Other cluster munitions are designed to destroy runways or electric power transmission lines.
The Russian Federation is known to possess or have possessed three types of weapons of mass destruction: nuclear weapons, biological weapons, and chemical weapons. It is one of the five nuclear-weapon states recognized under the Treaty on the Non-Proliferation of Nuclear Weapons and one of the four countries wielding a nuclear triad.
The United States is known to have possessed three types of weapons of mass destruction: nuclear, chemical, and biological weapons. As the country that invented nuclear weapons, the U.S. is the only country to have used nuclear weapons on another country, when it detonated two atomic bombs over two Japanese cities of Hiroshima and Nagasaki during World War II. It had secretly developed the earliest form of the atomic weapon during the 1940s under the title "Manhattan Project". The United States pioneered the development of both the nuclear fission and hydrogen bombs. It was the world's first and only nuclear power for four years, from 1945 until 1949, when the Soviet Union produced its own nuclear weapon. The United States has the second-largest number of nuclear weapons in the world, after the Russian Federation.
The Defense Threat Reduction Agency (DTRA) is both a defense agency and a combat support agency within the United States Department of Defense (DoD) for countering weapons of mass destruction and supporting the nuclear enterprise. Its stated mission is to provide "cross-cutting solutions to enable the Department of Defense, the United States Government, and international partners to Deter strategic attack against the United States and its allies; Prevent, reduce, and counter WMD and emerging threats; and Prevail against WMD-armed adversaries in crisis and conflict." DTRA is headquartered in Fort Belvoir, Virginia. The DTRA mission, organization and management, responsibilities and functions, relationships, authorities, and administration are defined in DoD Directive 5105.62, Defense Threat Reduction Agency (DTRA).
The Bureau of International Security and Nonproliferation (ISN) is a bureau within the United States Department of State responsible for managing a broad range of nonproliferation and counterproliferation functions. The bureau leads U.S. efforts to prevent the spread of weapons of mass destruction, their delivery systems, advanced conventional weapons, and related materials, technologies, and expertise.
War can heavily damage the environment, and warring countries often place operational requirements ahead of environmental concerns for the duration of the war. Some international law is designed to limit this environmental harm.
Libya pursued programs to develop or acquire weapons of mass destruction from when Muammar Gaddafi seized control of Libya in 1969 until he announced on 19 December 2003 that Libya would voluntarily eliminate all materials, equipment and programs that could lead to internationally proscribed weapons. This included weapons of mass destruction and long-range ballistic missiles.
This article deals with activities of the U.S. Central Intelligence Agency, specifically dealing with arms control, weapons of mass destruction (WMD) and weapons proliferation. It attempts to look at the process of tasking and analyzing, rather than the problem itself, other than whether the CIA's efforts match its legal mandate or assists in treaty compliance. In some cases, the details of a country's programs are introduced because they present a problem in analysis. For example, if Country X's policymakers truly believe in certain history that may not actually be factual, an analyst trying to understand Country X's policymakers needs to be able to understand their approach to an issue.
The UN Office for Disarmament Affairs (UNODA) is an Office of the United Nations Secretariat established in January 1998 as the Department for Disarmament Affairs, part of United Nations Secretary-General Kofi Annan's plan to reform the UN as presented in his report to the General Assembly in July 1997.
The Convention on Cluster Munitions (CCM) is an international treaty that prohibits all use, transfer, production, and stockpiling of cluster munitions, a type of explosive weapon which scatters submunitions ("bomblets") over an area. Additionally, the convention establishes a framework to support victim assistance, clearance of contaminated sites, risk reduction education, and stockpile destruction. The convention was adopted on 30 May 2008 in Dublin, and was opened for signature on 3 December 2008 in Oslo. It entered into force on 1 August 2010, six months after it was ratified by 30 states. As of December 2023, a total of 124 states are committed to the goal of the convention, with 112 states that have ratified it, and 12 states that have signed the convention but not yet ratified it.a
An explosive weapon is a weapon that uses an explosive to project blast and/or fragmentation from a point of detonation.
A chemical weapon (CW) is a specialized munition that uses chemicals formulated to inflict death or harm on humans. According to the Organisation for the Prohibition of Chemical Weapons (OPCW), this can be any chemical compound intended as a weapon "or its precursor that can cause death, injury, temporary incapacitation or sensory irritation through its chemical action. Munitions or other delivery devices designed to deliver chemical weapons, whether filled or unfilled, are also considered weapons themselves."
The Assistant Secretary of Defense for Nuclear, Chemical & Biological Defense Programs, or ASD(NCB), is the principal adviser to the Secretary of Defense, Deputy Secretary of Defense and the Under Secretary of Defense for Acquisition and Sustainment on policy and plans for nuclear, chemical, and biological defense programs.
The United States chemical weapons program began in 1917 during World War I with the creation of the U.S. Army's Gas Service Section and ended 73 years later in 1990 with the country's practical adoption of the Chemical Weapons Convention. Destruction of stockpiled chemical weapons began in 1986 and was completed on July 7, 2023. The U.S. Army Medical Research Institute of Chemical Defense (USAMRICD), at Aberdeen Proving Ground, Maryland, continues to operate.
