Chemical Weapon
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." Chemical weapons are classified as weapons of mass destruction (WMD), though they are distinct from nuclear weapons, biological weapons, and radiological weapons. All may be used in warfare and are known by the military acronym NBC (for nuclear, biological, and chemical warfare). Weapons of mass destruction are distinct from conventional weapons, which are primarily effective due to their explosive, kinetic, or incendiary potential. Chemical weapons can be widely ...

Sulfur Mustard
Mustard gas or sulfur mustard are names commonly used for the organosulfur chemical compound bis(2-chloroethyl) sulfide, which has the chemical structure S(CH2CH2Cl)2, as well as other species. In the wider sense, compounds with the substituents are known as ''sulfur mustards'' or '' nitrogen mustards'', respectively, where X = Cl or Br. Such compounds are potent alkylating agents, making mustard gas acutely and severely toxic. Mustard gas is a carcinogen. There is no preventative agent against mustard gas, with protection depending entirely on skin and airways protection, and no antidote exists for mustard poisoning. Also known as mustard agents, this family of compounds comprises infamous cytotoxins and blister agents with a long history of use as chemical weapons. The name ''mustard gas'' is technically incorrect; the substances, when dispersed, are often not gases but a fine mist of liquid droplets that can be readily absorbed through the skin and by inhalation. The ski ...

Changde Chemical Weapon Attack
The Battle of Changde (Battle of Changteh; ) was a major engagement in the Second Sino-Japanese War in and around the Chinese city of Changde (Changteh) in the province of Hunan. The purpose of the Japanese offensive was to maintain pressure on the Chinese National Revolutionary Army to reduce its combat ability in the region and its ability to reinforce the Burma Campaign. The Japanese were initially successful in their offensive operation by bacteria-infected bombs and captured parts of the city of Changde, which forced civilians to evacuate. The Japanese were pinned down in the city by a Chinese division long enough for other Chinese units to surround them with a counterencirclement. Heavy casualties and the loss of their supply lines then forced the Japanese to withdraw, which returned territorial control to the original status quo. Some contemporary Western newspapers depicted the battle as a Chinese victory. American government film footage showed victorious Chinese ...

Chemical Weapons Convention
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, Netherlands. The treaty entered into force on 29 April 1997. It prohibits the use of chemical weapons, and the large-scale development, production, stockpiling, or transfer of chemical weapons or their precursors, except for very limited purposes (research, medical, pharmaceutical or protective). 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. 193 states have become parties to the CWC and accept its obligations. Israel has signed but not ratified the agreement, while three o ...

Red Army
The Workers' and Peasants' Red Army, often shortened to the Red Army, was the army and air force of the Russian Soviet Republic and, from 1922, the Soviet Union. The army was established in January 1918 by a decree of the Council of People's Commissars to oppose the military forces of the new nation's adversaries during the Russian Civil War, especially the various groups collectively known as the White Army. In February 1946, the Red Army (which embodied the main component of the Soviet Armed Forces alongside the Soviet Navy) was renamed the "Soviet Army". Following the dissolution of the Soviet Union it was split between the post-Soviet states, with its bulk becoming the Russian Ground Forces, commonly considered to be the successor of the Soviet Army. The Red Army provided the largest land warfare, ground force in the Allies of World War II, Allied victory in the European theatre of World War II, and its Soviet invasion of Manchuria, invasion of Manchuria assisted the un ...
