Only __________ ___ ______ wear rank and rate insignia on their caps.

The correct answer is that only officers and chiefs wear rank and rate insignia on their caps. In military uniforms, rank insignia is a key feature that signifies an individual's level of authority and role within the organization. Officers and chiefs hold positions of leadership and responsibility that require them to display their rank visibly. This not only enables others to identify their position but also helps to establish the command structure.

Enlisted personnel, while they do have rank insignia, typically do not display it in the same manner on their caps in a ceremonial context. Instead, they may wear it on their uniforms in different placements. This distinction is critical for maintaining the military hierarchy and ensuring that commands and leadership roles are easily recognized by all personnel within the force and during formal events.
