What rank is held by an individual with one eagle above 1 rocker above 3 chevrons?

The rank indicated by the insignia of one eagle above one rocker above three chevrons is that of a Chief Petty Officer. In the Navy's rating system, the chevrons represent the enlisted rank, where each chevron signifies a certain level of service and experience. The eagle symbolizes the Chief Petty Officer position, which denotes a leader among enlisted personnel.

The structure includes three chevrons for the base rank of Petty Officer First Class, which is a lower rank than Chief Petty Officer. The rocker, representing the first level of leadership, must be accompanied by the eagle to denote that the individual has advanced to the Chief level. Therefore, the combination of the eagle, rocker, and chevrons correctly identifies the rank of Chief Petty Officer.

Understanding this insignia is crucial for recognizing rank in military settings, as it conveys not just the individual's position but also their level of responsibility and experience.
