German medical personnel made use of a variety of devices that designated their non-combatant status. Armbands were virtually universal, but tabards and specially painted helmets also saw use.

Whether medics were permitted under the Geneva Convention to carry personal arms for defense of themselves and their patients was a disputed point during the war. The American military said no; the Germans said yes. My personal belief is that the wording allowed it. Field medics generally carried pistols, although larger medical formations were authorized rifles, submachine guns, and machine guns (though these were probably used by non-medical specialists within the unit).
