Nurses may wear a pin at the base of the collar or at the top center of the apron bib. Acceptable pins are: a plain enameled red cross shape with a white outline border; or a circular pin with dark blue or black border, a red cross in the center, and the words "Deutsches Rotes Kreuz" or "Hilfschwester" on the border.
* Note: Pins must not have any Nazi symbols on them.
(* Note: If steel helmets are required, it seems that gas masks should likewise be mandatory. If you need a helmet to protect you because you are in the range of ballistic effects, you are also within range of chemical effects.)
