# Eastern Military District (Sweden)

Eastern Military District (Swedish: Östra militärområdet, Milo Ö), originally IV Military District (Swedish: IV. militärområdet) was a Swedish military district, a command of the Swedish Armed Forces that had operational control over Eastern Sweden, for most time of its existence corresponding to the area covered by the counties of Östergötland, Södermanland, Stockholm, Uppsala and Västmanland. The headquarters of Milo Ö were located in Strängnäs.

## History

Milo Ö was created in 1966 along with five other military districts as part of a reorganisation of the administrative divisions of the Swedish Armed Forces. It can be seen as the successor of IV Military District (IV. militärområdet) created in 1942, but that did not have the same tasks as Milo Ö. The military area consisted of the land covered by the above-mentioned counties, and from the creation to 1982, also the southern part of Gävleborg County. In 1991, the number of military districts of Sweden was decreased to five, and as a consequence of that, Milo Ö was merged with Bergslagen Military District (Milo B) to create a new military district, Middle Military District (Milo M).
