It might have been thought that the changes which have taken place within the former Soviet Union, the need for an understanding of nuclear weapons has disappeared. However, these weapons are no longer the sole preserve of five large nations. A significant number of other countries are now capable of developing nuclear weapons, and are likely to be much less reluctant to use them in conflict. The study of nuclear weapons and their effects remains relevant and essential. This volume provides an understanding of the weapons and their outputs, and how these affect men and equipment on land, sea and in the air. It investigates the steps which can be taken to mitigate these effects, and how survivability can be assessed.
