Military service by British royalty

Many members of the British royal family have seen service in the British Armed Forces or other Commonwealth militaries, and others hold honorary ranks or positions. This is a list detailing formal military service by members of the British royal family.

There is also a list of military titles, service appointments, and various job titles within the royal family, which is listed below. These roles are honorary and may, or may not, also be held by Royals who are ex-military or serving military persons.

For example, Princess Anne, whilst not having any military service, holds many ranks and roles within the British Armed Forces.

List
The honorary ranks and titles are included in a separate column. The "rank whilst active" column dictates the rank worn and held whilst the person was serving with the armed forces and the "current rank worn" column denotes any rank worn currently (including honorary rank and promotions). Members of the royal family receive regular promotions even after their active service has ended.
