Flag Officer

A flag officer is a commissioned officer in any armed forces senior enough to be entitled to fly a flag to mark the position from which the officer exercises command.

The generic title of flag officer is used to denote those who hold the rank of rear admiral (or its equivalent) and above, also called "flag ranks"; in the Fleet, this also includes the rank of commodore. Flag officer corresponds to the generic terms general officer and air officer.

A flag officer sometimes has a junior officer, called a flag lieutenant or flag adjutant, attached as a personal adjutant or aide-de-camp.
