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 dispe ...

Sulfur Mustard
Mustard gas or sulfur mustard is a chemical compound belonging to a family of cytotoxic and blister agents known as mustard agents. The name ''mustard gas'' is technically incorrect: the substance, when dispersed, is often not actually a gas, but is instead in the form of a fine mist of liquid droplets.https://www.acs.org/content/dam/acsorg/education/resources/highschool/chemmatters/gc-mustard-gas-personal-safety-and-natl-security.pdf Mustard gases form blisters on exposed skin and in the lungs, often resulting in prolonged illness ending in death. The active ingredient in typical mustard gas is the organosulfur compound bis(2-chloroethyl) sulfide. In the wider sense, compounds with the structural element are known as ''sulfur mustards'' and ''nitrogen mustards'', respectively. Such compounds are potent alkylating agents, which can interfere with several biological processes. History as chemical weapons As a chemical weapon, mustard gas was first used in World War I, and has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. During the battle, the Imperial Japanese Army extensively used chemical weapons. The purpose of the Japanese offensive was not to hold the city but 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. However, the Japanese were pinned down in the city by a single 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 W ...

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, The Netherlands. The treaty entered into force on 29 April 1997, and prohibits the large-scale use, development, production, stockpiling and transfer of chemical weapons and 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. As of August 2022, 193 states have become parties to the CWC and accept its obligations. Israel has signed but not ratified the agreement, while three other U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

However, Jilin's economy, characterized by heavy industry, has been facing economic difficulties with privatization. This prompted the central government to undertake a campaign called "Revitalize the Northeast". The region contains large deposits of oil shale.

The Republic of China Army (ROCA), previously known as the Chinese Nationalist Army or Nationalist Revolutionary Army and unofficially as the Taiwanese Army, is the largest branch of the Republic of China Armed Forces. An estimated 80% of the ROC Army is located on Taiwan, while the remainder are stationed on the Penghu, Kinmen, Matsu, Dongsha and Taiping Islands. Since the Chinese Civil War, no armistice or peace treaty has ever been signed, so as the final line of defense against a possible invasion by the People's Liberation Army (PLA), the primary focus is on defense and counterattack against amphibious assault and urban warfare. Organization The ROC Army's current operational strength includes 3 armies, 5 corps. As of 2005, the Army's 35 brigades include 25 infantry brigades, 5 armoured brigades and 3 mechanized infantry brigades.
