The military aircraft insignia of 186 countries are covered in this essential introduction to their general history. Extensive country-by-country listings give the reader a brief history of the military air activity of a particular country and the political reasons for any changes to the insignia. Each country is accompanied by full-color line drawings showing the national markings of the era positioned on the typical aircraft that were operational at the time. This invaluable reference addresses the serious absence of adequate information about the national insignia of military aircraft and will appeal to modelers, aviation historians, and those interested in flags and heraldry. Over five hundred illustrations are included.
