What is the designation for a person holding the rank of Petty Officer Third Class?

The rank of Petty Officer Third Class is designated as E-4 in the United States Navy and Coast Guard. The "E" stands for "enlisted," and the number indicates the rank level within the enlisted hierarchy.

Petty Officer Third Class is the first level of the Petty Officer rank, and its designation signifies an individual who has moved beyond the basic Seaman ranks (E-1, E-2, E-3) and has taken on technical and supervisory responsibilities. This rank represents a position that requires both demonstrated skills in a specific area and an increased level of leadership, as individuals in this role often assist in training junior personnel and may lead small teams.

Understanding rank designations is crucial for recognizing the structured hierarchy that exists within the military, which helps in administering duties and responsibilities effectively. The incorrect options reflect ranks that are either below or above the correct designation, leading to confusion about the structure of enlisted ranks.
