Which is NOT a part of the JROTC uniform?

The choice of swim trunks as the answer highlights a clear distinction between what is typically included in a JROTC uniform. A JROTC uniform is designed to present a formal and cohesive appearance that reflects military standards. It consists of components such as a shirt and tie, combat boots, and a jacket with insignia, all of which serve to signify the values of discipline, uniformity, and respect within the program.

Swim trunks, on the other hand, do not fit within the context of the JROTC uniform. They are casual clothing items geared towards water activities and do not convey the formal military attire required for JROTC activities, events, or ceremonies. This difference underscores the importance of wearing appropriate attire that aligns with the values and expectations of the JROTC program, making swim trunks an unsuitable option in this context.
