Eastern Military Area

Eastern Military Area (Östra militärområdet, Milo Ö), originally IV Military Area (IV. militärområdet) was a Swedish military area, 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 areas as part of a reorganisation of the administrative divisions of the Swedish Armed Forces. It can be seen as the successor of IV Military Area (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 areas of Sweden was decreased to five, and as a consequence of that, Milo Ö was merged with Bergslagen Military Area (Milo B) to create a new military area, Middle Military Area (Milo M).
