The Supreme Commander (Swedish: överbefälhavaren; acronym: ÖB) is the highest ranked professional military officer in the Swedish Armed Forces, and is by NATO terminology the Swedish chief of defence equivalent. The Supreme Commander is the agency head of the Swedish Armed Forces and formally reports to the Government of Sweden, though normally through the Minister for Defence.[2][lower-alpha 2] The primary responsibilities and duties of the Supreme Commander (and the charter for the Armed Forces) are prescribed in an ordinance issued by the Government.[3]
