The first traces of a Swedish general staff were in Gustavus Adolphus's army.

[2] A quartermaster general already existed in the time of John III, but his activities were first decided by Charles X Gustav.

According to this instruction, the General Staff then formed a special corps and consisted of a general officer as its chief, 17 senior adjutants (2 colonels, 3 lieutenant colonels, 12 majors) and 30 staff adjutants (20 captains, 10 lieutenants) and 1 professor, 1 military archivist and 1 actuary, 1 librarian and others.

The other was called the Technical Department and devoted themselves to telegraphy, telephone, balloons, aircraft, automobiles and more.
