Collar tabs, also known as shoulder marks, are insignia worn on the collars or shoulders of military, paramilitary, police, fire, and security service uniforms. They typically indicate rank, unit, branch of service, or other distinctions, and can vary greatly in design and complexity depending on the organization and country. These small, yet significant emblems play a crucial role in identifying and distinguishing personnel within various organizations, fostering a sense of unity, pride, and hierarchy. Collar tabs often carry rich historical and cultural symbolism, reflecting the traditions and values of the organization they represent. They serve as a visual representation of an individual's position, experience, and accomplishments within the organization, contributing to a sense of camaraderie and esprit de corps.
