These three volumes contain compact information about our country's civic structure and its national defense. The first is really a citizen's handbook, with text of Constitution, Monroe Doctrine, Presidents of the United States with brief biographies, etc. The second is about the organization of Army, Navy, and Marine Corps--work, equipment, uniforms, and insignia, classification of naval vessels, etc. The third is about the Army and Navy Air forces, with 30-odd fighting planes and appropriate information about them.
