From what I have seen thus far, I don't believe there was a differentiation between "combattant" and "non-combattant". I think its' intent was more a "participant" type status, but the very late institution prevented it from being issued en-masse, as it were. I think exceptional conduct/bravery received a higher grade of award along the lines of the Carl-Eduard Medal, etc... Mark's group is interesting in that we have a S-C-G Medal mounted on a Sax-Ernestine ribbon. I don't think I've seen more than a handful of these mounted like this, but they absolutely occur in groups. Why, unfortunately, we'll never know. Was there some significance that's not recorded in statutes? Was it a "personal preference" issue? This remains one of the more interesting anomolies of Imperial era collecting.
