A defence district[1][2] (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.
