OPIL consisted of four staffs : In connection with the formation of the Joint Forces Command , it was initially placed to various buildings in central Stockholm . As a permanent place , the government proposed that the staff should be placed in Bålsta . No decision was made on this matter , but was put to further investigation . The Swedish Armed Forces reported different location options , including Bålsta , Muskö naval base and Uppsala-Ärna Airport , where they themselves advocated Bålsta . All options would involve an investment of approximately SEK 300-400 million . On behalf of the Ministry of Defence , the Swedish Armed Forces investigated further alternative localizations within the Stockholm area , where they proposed a location to Näsbypark in Täby Municipality . Placing the staff to Näsbypark would include an investment of approximately SEK 260 million . The premises were also considered flexible for future changes in operations , and could be adapted without extensive new buildings construction . The government 's proposal was based on the fact that the location of the Joint Forces Command in Näsbypark was to begin on 1 April 2002 , and as a whole be located there no later than 31 December 2004 . After the September 11 attacks the government highlighted vulnerability with conventional buildings , civilians and buildings in connection with an attacker 's target . Consequently , the decision to locate the Joint Forces Command to Näsbypark was repealed . As an alternative to Näsbypark , it was decided that the Joint Forces Command should be located at Uppsala-Ärna Airport no later than 31 December 2004
