What is the purpose of insignia worn on a uniform?

The purpose of insignia worn on a uniform is to denote rank or rate, occupational specialty, or warfare qualification. Insignia serve as a visual representation of a service member's position within the military hierarchy, allowing for the quick identification of an individual's authority and expertise. For example, the rank insignia indicates a person's level of responsibility and command within the Navy, while occupational specialty insignia highlights specific skills or qualifications that a service member possesses, such as those related to particular areas of expertise or warfare capabilities. This system of insignia not only fosters respect and recognition among service members but also aids in maintaining order and discipline within the ranks.

While insignia can sometimes show personal achievements or indicate years of service, these elements are not the primary focus of insignia on a uniform. Additionally, although insignia may represent the service branch to some extent, the primary function is to provide clear information regarding an individual's rank and qualifications.
