# Defence district

A defence district (Swedish: Försvarsområde, Fo) was a military subdivision of the Swedish Armed Forces created in 1914. It was a lower regional level subdivision, usually corresponding to a Swedish county. The commander of a defence district was the Defence District Commander, who usually commanded local defence units, including infantry, engineers, air defence and light artillery, as well as any Home Guard units in the district. The commander answered to the larger military district that the defence district was part of.

## History

A defence district was the lowest regional unit in the Swedish Armed Forces. Such were found in particularly important coastal areas during World War I and from 1939 on at a time of mobilization. From 1943 they were included as part of the ordinary peace organization. The district was responsible for defence planning, home defence, supervision of fixed facilities, certain territorial units and the Home Guard equipment and equipment. In 1973-76, the defence districts were amalgamated with regiments into defence district regiments (försvarsområdesregementen) (except Fo 67, which remained independent), but in the early 1990s some independent defence districts again were formed. These latter districts were disbanded as a result of the Defence Act of 1996. The locations of the defence districts are often indicated by their names. A defence district has usually been matched by a Swedish county except in Norrbotten where there were three defence districts.
