This is a non-technical narrative of chemical, biological warfare and terrorism (CBWT) for the general, non-scientist, non-military background reader. It examines the scientific and military basis and considerations behind the use of chemical and biological agents to injure and kill people. It explains in the simplest terms possible the various agent types, their use, effects on people, how they injure or kill, and the means of detection, treatment, antidotes and decontamination. Where technical terms are introduced, they are clearly and simply defined. The tactical considerations for the use of CBWT agents also is explained as it applies to terrorist use against civilian populations. The book also views the nature of the threat to civilians, self-defence and warning techniques, and measures one may take to protect family and self if living near a chemical plant. It is for education and where possible, self-defence and awareness. After all, the greatest weapons used by the terrorist is ignorance and fear.
