Just a random morning thought: What if medics had something distinct that stood out from their outfit that made them have a better time approaching allies.
I know the uniforms themselves exist. However, I feel like in the heat of combat. Its still very unrecognizable. Would be much better off investing in a ghille so you stood out as that silly bush middle of the desert.
So what about implementing a light green hue from their medical uniforms? They already accept the risk when putting it on, knowing they will be targetted. Or for putting the title overhead. So why not make it just a little visually easier for the ones lost in the sauce needing their heals?
I think offering them a cool green hue to wear thats built into their uniforms would give them a great option to say yes or no to a feature that would allow a lot more people to know where their meds are.
