Editing Chemical warfare (section)

====Classes====
Chemical weapons are agents that come in four categories: [[Pulmonary agent|choking]], [[Vesicant|blister]], [[Blood agent|blood]] and [[Nerve agent|nerve]].<ref>Gray, Colin. (2007). ''Another Bloody Century: Future Warfare''. p. 269. Phoenix. {{ISBN|0-304-36734-6}}.</ref>  The agents are organized into several categories according to the manner in which they affect the human body. The names and number of categories varies slightly from source to source, but in general, types of chemical warfare agents are as follows:

There are other chemicals used militarily that are not scheduled by the CWC, and thus are not controlled under the CWC treaties. These include:
* [[Defoliant]]s and [[herbicide]]s that destroy vegetation, but are not immediately toxic or poisonous to human beings. Their use is classified as [[herbicidal warfare]]. Some batches of [[Agent Orange]], for instance, used by the British during the [[Malayan Emergency]] and the United States during the [[Vietnam War]], contained [[Polychlorinated dibenzodioxins|dioxins]] as manufacturing impurities. [[Dioxins and dioxin-like compounds|Dioxins]], rather than Agent Orange itself, have long-term cancer effects and for causing genetic damage leading to serious [[birth defects]].
* [[Incendiary device|Incendiary]] or [[Explosive material|explosive]] chemicals (such as [[napalm]], extensively used by the United States during the [[Korean War]] and the Vietnam War, or [[dynamite]]) because their destructive effects are primarily due to fire or explosive force, and not direct chemical action. Their use is classified as [[conventional warfare]].
* [[Virus]]es, [[bacteria]], or other organisms. Their use is classified as [[biological warfare]]. [[Toxin]]s produced by living organisms are considered chemical weapons, although the boundary is blurry. Toxins are covered by the [[Biological Weapons Convention]].
