Medics wear distinctive helmets with a red cross. Hoping the enemy won’t fire on them. They don’t even carry extra ammunition.  They are in the business of saving lives, not taking them. In Tennessee, we even have a law prohibiting carrying a weapon "for the purposes of being armed..." & concealed carry is allowed.
