A Manual of United States and Foreign Armed Forces Uniforms, Insignia, and Organization

The manual of Military Uniforms is being published in installments as material on various foreign countries becomes available. This looseleaf booklet permits alphabetical arrangement of countries or any other arrangement that is desired. All information concerning the uniforms, insignia, and description of the Armed Forces of each country has been furnished by the government of that country. The first installment, published early in 1960, had pages on Canada, Denmark, France, Federal Republic of Germany, Greece, Italy, Luxem-bourg, Netherlands, and the United Kingdom. The second section included Brazil, Haiti, Iran, Israel, Japan, Republic of Korea, Norway, Philippines, and Pakistan. This, the third section, consists of Australia, Portugal, Spain, Turkey, United States, and Viet-Nam. U.S. women's military uniforms will be represented in a later installment and can then be inserted with the other U.S. uniforms.
