Naval rank refers to the hierarchical system used to classify personnel in a navy. It establishes authority, responsibilities, and the chain of command within naval forces. Ranks typically range from enlisted personnel, such as seamen, to commissioned officers, like captains and admirals. Each rank has specific duties and privileges, influencing promotions and career progression. Different countries have their own naval rank structures, but many share similar titles and roles. For example, the United States Navy uses a system that includes ranks such as lieutenant and rear admiral. Understanding these ranks is essential for effective communication and operations within naval organizations.
