What are CBRN weapons?

  • CBRN weapons have the capability of creating mass casualties as well as mass disruption and therefore, are classified as weapons of mass destruction.
    • According to a 2005 study, the range of these weapons is quite extensive.
  • Chemical weapons include mustard gas (which damages the respiratory tract, skin, and eyes) and nerve agents (victims rapidly become unconscious, have breathing difficulties, and may die).
  • Biological agents like anthrax (causes fever, malaise, cough, and shock. Death can be within 36 hours), botulinum toxin (leads to paralysis of respiratory muscles) and plague are some examples of biochemical weapons. Radiological weapons include weaponised radioactive waste and dirty bombs as well as nuclear weapons.
  • The first instance of any form of CBRN weapons being used in modern warfare can be traced back to World War I.
    • The French forces, during the first month of the war, deployed tear-gas grenades that they had developed in 1912 for police use.
    • Later, Germany, in October 1914, fired shells containing dianisidine chlorosulfate, a lung irritant, at the British army at Neuve-Chapelle in France.
