What type of fabric should rating badges with white backgrounds be made of?

Rating badges with white backgrounds should be made of a fabric that matches the uniform to ensure consistency and cohesion in appearance. This alignment with the uniform's fabric promotes a professional and polished look, which is essential in maintaining the standards of dress within the military environment. Using a fabric that matches the uniform facilitates a streamlined aesthetic, helping to unify the overall appearance of personnel and their insignia.

Matching the badge fabric to the uniform also helps in distinguishing rank and position effectively while reinforcing the identity of the service member within the organization. It is important for badges to be clearly identifiable against the uniform, ensuring that they serve their purpose of signifying rank and qualifications without causing any visual distraction.

In contrast, the other options do not provide the proper guidelines for the appearance of rating badges. Using contrasting fabrics or mismatched materials would create an inconsistent look that could detract from the professionalism expected in military dress.
