Naval ranks are a system used to classify the hierarchy and responsibilities of personnel in a navy. They typically range from enlisted personnel, such as seamen, to commissioned officers, like captains and admirals. Each rank has specific duties, authority, and pay grades, which help maintain order and efficiency within naval operations. In many navies, ranks are divided into three main categories: enlisted ranks, officer ranks, and flag ranks. Enlisted personnel usually perform technical and operational tasks, while officers are responsible for leadership and strategic planning. Flag ranks, such as rear admiral and vice admiral, denote senior leadership positions, often overseeing large units or entire fleets.
