Submachine Guns
MP40
The MP40 is used by SS soldiers throughout the season. Alfred, Neil and Harry briefly use them alongside a couple of Union Corse crooks during a raid on Gestapo Headquarters in Poitiers in "Kiss of Death". A resistance fighter named Anton (Nicolas Carpentier) seizes one from a SS soldier in "Into the Fire".
