But didn’t that ship sail a century ago?
Since exactly everything related to medical services/material/staff uses a red cross in the physical world, isn’t it natural that it does in movies (or games)? Is the argument here that it can be used when depicting proper use (e.g war movie or war game) but shouldn’t be used more than that since that’s the rule in the real world? That at least makes some sense.
I have been an army medic myself with a red cross armband and while I knew that this was somehow related to the Geneva convention I wasn’t actually aware that it was the exclusive right of military medical staff. Every single gadget/vehicle/facility is plastered with the symbol so it sure feels like the generic “medical whatever” symbol.
Not saying getting here from there is ready. But it may be possible.
