Which collar insignia signifies a Chief Warrant Officer 5 (CWO5) in the Marine Corps?

The insignia that signifies a Chief Warrant Officer 5 (CWO5) in the Marine Corps is described as a single silver bar device with a thin red break in the center. This distinct insignia is part of the broader insignia system used within the Marine Corps to indicate rank and position, providing clear visual identification of a service member's level of authority.

Warrant Officers occupy a unique role that is subordinate to commissioned officers but above enlisted ranks. The specific design of the CWO5 insignia reflects their advanced experience and qualifications, distinguishing them from other warrant officer ranks. The use of a thin red break in the center of the silver bar not only symbolizes the rank but also helps in ensuring clarity and ease of identification among various officers, particularly during formal settings or inspections.

In contrast, the other choices represent insignia for different ranks. For example, the single gold bar typically represents a junior officer, not aligned with the CWO5 designation. The single bar device with a red background and two breaks or one break would correspond to different ranks within the warrant officer or commissioned officer ranks, thus clarifying their rank and hierarchy within the Marine Corps.
