Switzerland was a strict neutral during WWII, but although it avoided
openly siding with either the Axis or Allies, a small number
of Swiss citizens without offical approval did actually volunteer for
service within the German Wehrmacht. In fact, between 700 and 800
Swiss volunteers are known to have been incorporated in the Wehrmacht
during WWII. Of these, at least 300 are thought to have been killed in
action. No single unit of Swiss volunteers was formed during WWII though,
and all volunteers served on an individual basis within the Wehrmacht.
The vast majority of Swiss volunteers were accepted into
the ranks of the Waffen-SS, notebly in the 5.SS-Panzer-Division Wiking
and the SS-Standarte Kurt Eggers.
