I personally don't find cps having their digits and rank written on armband and exposed to everybody a good thing. The point of their masks is to make them anonymous, but this point is nullified by their armbands, which make them very easily recognizable by civilians who can easily remember the first one or two digits. This issue puts every single unit in danger, rebels will know who to kill first, personal revenges will happen to units who are more disliked by the polulace. I think this goes against the combine civil protection doctrine, which I believe is full anonymity (The canonic civil protection armband has C17:i7 written on it. I presume C17 stands as city 17 and i4 as maybe a specific section or precint of the city. No rank or ID is shown because it would make the mask pretty much useless if you think about it.) In short. I think units names should be hidden to civilians and simply changed to something along the lines of "A masked individual" or "An anonymous unit".
