Reposting in the correct thread...
The upgrade of the Swedish army during the early 90's would free up a lot of M/45 submachine-guns and 6,5mm Mauser rifles from the home guard. The home guard are upgraded to the AK4 (H&K G3) freed up from the Army. The Swedish police also replaced their version of the M/45 with H&K MP5.
I noticed that the
English Wikipedia page for the M/45 didn't mention the 9mmB ammunition. It is an overloaded version of the 9mm parabellum round, and all but the oldest ones can handle it.
If the Swedish army would involve itself on the continent (or elsewhere), all of those weapons would still be in storage and could be used to equip "support forces".
