The British Overseas Territories Citizenship (Designated Service) (Amendment) Order 2008
Section 16 of the British Nationality Act 1981 provides that a person born outside the British overseas territories after commencement of that Act will be a British overseas territories citizen in certain circumstances, including where at the time of birth his father or mother is a British overseas territories citizen and is serving outside the British overseas territories in service designated by the Secretary of State, recruitment for that service having taken place in a British overseas territory. Various types of service are designated for the purposes of this provision by the British Dependent Territories Citizenship (Designated Service) Order 1982.
