Boustedt served as captain in Älvsborg Regiment in 1910 and was promoted to major and appointed head of the Communications Department of the General Staff in 1912.

[2] In Sweden during the 1930s, ideas were born about Swedish-Finnish military cooperation for Finland's (and thus also Sweden's) defense with, among other things, the Swedish field army (plus the air force's 100 fighter aircraft) under a League of Nations flag on the Karelian Isthmus, protect Finland against an expected Soviet attack.

[3] As Chief of the General Staff, Boustedt, also disapproved of plans to make propaganda films intended to boost patriotic motivation among the conscripts.

In a letter to the Armé- och Marinfilm ("Army and Navy Film", AMF), written in 1931, Boustedt claimed that due to their individualistic national character, Swedish conscripts were suspicious of any manipulative efforts from the authorities.

Only films that had no obvious intention of guiding the viewers’ thinking in a certain direction could have a genuine influence on Swedish audiences, he argued.
