What does the insignia of Cadet Seaman indicate?

The insignia of a Cadet Seaman indicates that the individual holds the basic entry-level rank within the cadet program. In this case, having no rank insignia represents a position in which the cadet is beginning their training and has not yet progressed to a higher rank where specific insignia would be displayed. This lack of insignia is a way to signify that the cadet is still in the early stages of their training and education, focusing on learning fundamental skills and knowledge before advancing to ranks that are denoted with insignia, such as stripes or bars.

In other contexts, different insignia denote various ranks or levels of experience, but for a Cadet Seaman, the absence of any insignia highlights their status as a newcomer in the cadet program, emphasizing the importance of foundational training.
