Military insignia are symbols or badges worn on uniforms to signify rank, branch of service, or specific qualifications. These insignia help identify personnel and their roles within the military hierarchy. Common examples include rank insignia, which indicate a soldier's level of authority, and unit insignia, which represent the specific group or division to which a service member belongs. Insignia can be found on various parts of a uniform, such as sleeves, collars, or hats. They are often made from materials like metal, cloth, or embroidery. Understanding these symbols is essential for recognizing the structure and organization of the armed forces.
