Chemical Weapons (also called “the poor man’s atomic
bomb”) - chemical substances that can be delivered
using munitions and dispersal devices to cause death or
severe harm to people, animals, and plants
Biological Weapons (also called “germ weapon”) - a
weapon of mass destruction that uses a biological agent
or pathogen such as bacteria or a virus that is harmful
to people and plants
The use of biological weapons against an enemy for
hostile purposes or during armed conflict is called
biological warfare
Easy to produce and quantify
 Cheaper than nuclear weapons and overall
cheapest weapon
 Easy to conceal
 Conventional weapons (bombs, grenades, etc.)
explode once, kill a few hundred people, mutilate
thousands of others. Biological agents, on the
other hand, can spread from person to person,
killing more of the enemy
 Chemical weapons can give an army a tactical,
battlefield advantage
Backfire, since containment is difficult once a
contagious disease has begun spreading
 Difficult to deliver to the enemy
 Does not immediately incapacitate an enemy,
other weaponry is more effective
 Unpredictable, you may infect your own troops
 Lasts for a long time, for example, anthrax can live
in soil for up to 50 years
Bacteria- such as anthrax, brucellosis,
tularemia, and plague
 Viruses- intracellular parasites, smallpox, and
yellow fever
 Fungi- pathogens that can be weaponized for
use against crops to cause disease
 Toxins- poisons that are weaponized after
extraction from snakes, insects, spiders,
marine organisms and other animals
Mustard gas, Sarin, Chlorine, hydrogen cyanide,
tear gas, poisoned arrows, boiling tar, and
arsenic smoke
 Substances such as inflammatory or
combustible mixtures, smokes, or gases that
can irritate, burn, incapacitate, and poison
 The first chemical weapon used effectively in
battle was chlorine gas, which burns and
destroys lung tissue
