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.
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.
The law of war is the component of international law that regulates the conditions for initiating war and the conduct of warring parties. Laws of war define sovereignty and nationhood, states and territories, occupation, and other critical terms of law.
Incendiary weapons, incendiary devices, incendiary munitions, or incendiary bombs are weapons designed to start fires or destroy sensitive equipment using fire, using materials such as napalm, thermite, magnesium powder, chlorine trifluoride, or white phosphorus. Though colloquially often known as bombs, they are not explosives but in fact are designed to slow the process of chemical reactions and use ignition rather than detonation to start or maintain the reaction. Napalm, for example, is petroleum especially thickened with certain chemicals into a 'gel' to slow, but not stop, combustion, releasing energy over a longer time than an explosive device. In the case of napalm, the gel adheres to surfaces and resists suppression.
The Convention on the Prohibition of the Use, Stockpiling, Production and Transfer of Anti-Personnel Mines and on their Destruction of 1997, known informally as the Ottawa Treaty, the Anti-Personnel Mine Ban Convention, or often simply the Mine Ban Treaty, aims at eliminating anti-personnel landmines (APLs) around the world.
International humanitarian law (IHL), also referred to as the laws of armed conflict, is the law that regulates the conduct of war. It is a branch of international law that seeks to limit the effects of armed conflict by protecting persons who are not participating in hostilities and by restricting and regulating the means and methods of warfare available to combatants.
The Cluster Munition Coalition (CMC) is an international civil society movement, which campaigns against the use, production, stockpiling, and transfer of cluster munitions. Cluster munitions, a type of munition stockpiled by more than 80 states, are documented to have caused significant civilian deaths and injuries and have frequently caused indiscriminate effects in both conflict and peace times. Their use is prohibited under the 2008 Convention on Cluster Munitions, a convention formally endorsed on May 30, 2008, in Dublin, Ireland, and was signed by 94 countries in Oslo on December 3-4, 2008. The Convention entered into force, becoming a binding international law on August 1, 2010, after 30 countries formally ratified it. As of January 4, 2012, it had been signed by 111 countries, of which 77 have ratified.
The Protocol on Blinding Laser Weapons, Protocol IV of the 1980 Convention on Certain Conventional Weapons, was issued by the United Nations on 13 October 1995. It came into force on 30 July 1998. As of the end of April 2018, the protocol had been agreed to by 109 nations.
The Geneva International Centre for Humanitarian Demining is an international organisation working in mine action and explosive ordnance risk reduction, with a focus on landmines, cluster munitions and ammunition stockpiles. Based in the Maison de la paix in Geneva, it is legally a non-profit foundation in Switzerland.
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.
Air warfare must comply with laws and customs of war, including international humanitarian law by protecting the victims of the conflict and refraining from attacks on protected persons.
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 April 2023, a total of 123 states are committed to the goal of the convention, with 111 states that have ratified it, and 12 states that have signed the convention but not yet ratified it.
An explosive weapon is a weapon that uses high explosive to project blast and/or fragmentation from a point of detonation.
The Protocol on Prohibitions or Restrictions on the Use of Mines, Booby-Traps and Other Devices is a United Nations treaty that restricts the use of land mines, remotely delivered mines, and booby traps. It is Protocol II to the 1980 Convention on Certain Conventional Weapons.
The Protocol on Prohibitions or Restrictions on the use of Incendiary Weapons is a United Nations treaty that restricts the use of incendiary weapons. It is Protocol III to the 1980 Convention on Certain Conventional Weapons Which May Be Deemed To Be Excessively Injurious Or To Have Indiscriminate Effects. Concluded in 1981, it entered into force on 2 December 1983. As of January 2023, it had been ratified by 126 state parties.
New physical principles weapons are a wide range of weapons or systems created using emerging technologies, like wave, psychophysical, and genetic weapons.
Convention on Certain Conventional Weapons – Group of Governmental Experts on Lethal Autonomous Weapons Systems refers to a group of experts created by the United Nations in order to study legal, ethical, societal and moral questions that arise from the increased use of autonomous robots to carry weapons and to be programmed to engage in combat in various situations that might arise, including battles between countries, or in patrolling border areas or sensitive areas, or other similar roles.
In international humanitarian law and international criminal law, an indiscriminate attack is a military attack that fails to distinguish between military objectives and protected (civilian) objects. Indiscriminate attacks strike both military and protected objects alike, thus violating the principle of distinction between combatants and civilians. They differ from direct attacks against civilians and encompass cases in which the perpetrators are indifferent as to the nature of the target, cases in which the perpetrators use tactics or weapons that are inherently indiscriminate, and cases in which the attack is disproportionate, because it is likely to cause excessive civilian casualties and damages to protected objects.
