Hi, I think you know that there are only three insignias without flag. In my opinion (I do not know it exactly) the older ones are still wearing their "Without flag" insignia, because it looks better. But I do not know what the ZDv 37/10 says. Here the most soldiers of the German-French-Brigade wear the French type without the flag, mostly because this insignia is made in chrome-style. The chef-en-second once told me, that he wears the French and the commander, a French, wears the German with flag, because of showing their respect to each other. Michael
