As the chief rival to NATO from 1955 - 1991, the Warsaw Pact was, and has since remained, a popular subject for military students and historians alike. On the collecting market the vast range of awards, badges and insignia produced during the Cold War has helped to make the national armies of the Warsaw Pact a popular choice with many military specialists. Surprisingly, even though a great deal has been written about the armor, weapons, uniforms and equipment, no comprehensive reference source on the subject of badges has been printed in the English language.
