I totally agree with you. German Army was very well commanded, from the Armies headquarters since to the Stellvertreter, a kind of NCO, at that time of illiterate peasants the German workers provided many non-commissioned officers, or as it's better to say "Stellvertreter"
But a French 75 mm cannon Deport was as good as a 75 mm cannon made from Armstromg or Skoda or Krupp, or even by the italian Ansaldo.
