 Typically, one-star officers hold the rank of commodore, flotilla admiral, brigadier general, brigadier, or in the case of those air forces with a separate rank structure, air commodore.Officers of one-star rank are either the most junior of the flag, general and air officer ranks, or are not considered to hold the distinction at all.Specifically, in many navies, one-star officers are not considered to be flag officers, although this is not always the case.
