Which cadets are authorized to wear the Service Dress Blues?

The option indicating that officers, Chiefs, and Color Guard members are authorized to wear the Service Dress Blues is correct because the dress code typically associated with military or cadet training programs is structured to designate specific uniforms for different ranks and roles within the organization. Officers and Chiefs are often recognized by their distinct uniforms that signify their ranks, and the Color Guard, which represents ceremonial responsibilities, also wears the Service Dress Blues to uphold the formal standards during public appearances and functions.

The Service Dress Blues are meant to present a professional appearance and reflect the tradition of the organization, making it relevant for these specific groups tasked with responsibilities that place them in the public eye. This uniform is not worn by all ranks across the board, as different types of uniforms, including less formal or combat uniforms, may be designated for enlisted personnel not serving in these specific roles or ranks.
