Comparative navy officer ranks of the Commonwealth

Rank comparison chart of naval forces of Commonwealth of Nations states.

Most of the 52 commonwealth nations have their beginnings in British Empire and have shared naval traditions. By comparison Mozambique is a former Portuguese colony. Even after some had achieved a degree of independent government from the UK, their naval protection was still British; the Royal New Zealand Navy did not exist separately until 1941.
