Found out that there is a second version of both the 1st and 2nd class that not has the text "Dem Verwundeten Soldaten", but "IM Diensten Verletzt" . The first means "The Wounded Soldier", the second "Wounded in service". The amount of stripes on the changable ribbon is the same as the amount of wounds received. 6 green stripes for 6 wounds, five for five wounds, and so on till the ones in the photos here for one wound. The 1st Class is being awarded for wounds that have effect on the rest of the persons live. For wounds that give the person a handicap. The effects of the wound have to last. For wounds that "heal", the 2nd class was obtained.
