666 First-Aid Man

Appendix B identifies SSN 666 as First-Aid Man under AR 615-26 of September 1942 and its supplements, with no June 1945 Marine Corps title. The notation “None” means no Marine Corps specialty existed for that earlier classification; it does not establish a conversion to SSN 845 or any other replacement.
