What is one characteristic that distinguishes cadets' uniforms from those of commissioned officers?

The characteristic that distinguishes cadets' uniforms from those of commissioned officers is that cadets do not wear commissioned officer rank insignia. This is significant because the lack of officer rank insignia indicates that cadets are still in training and have not yet attained the rank or authority of a commissioned officer. In contrast, commissioned officers wear specific insignia that represents their rank and duties within the Navy or the military service. This differentiation in uniforms helps to visually convey the level of training and responsibility that cadets and officers hold within the military structure. Other distinguishing features might include insignia that represent various ranks, achievements, or affiliations, but the absence of officer rank insignia is a clear and defining characteristic of cadet uniforms.
