U.S. Chemical and Biological Defense Respirators: An Illustrated History is a historical overview of United States military and civilian defense respirator developments spanning the period from the beginnings of CBW respiratory protection in the First World War. Accompanied by photographs, illustrations and other supplemental material, the book may serve as a valuable reference for military historians, NBC defense specialists concerned with the design, development and evolution of military and civil individual protection against war agents, and even collectors of military memorabilia. In view of the fact that no reference work of this type has ever before been prepared, U.S. Chemical and Biological Defense Respirators provides an informational starting point for individuals interested in developing personal understanding about a relatively exotic and important area of modern defensive technology.
