889 Radio Mechanic M

Appendix B identifies SSN 889 as “Radio Mechanic M” under AR 615-26 of September 1942 and its supplements, and suggests SSN 774 as a possible replacement. This was not an automatic conversion: each affected Marine’s Qualification Card had to be reviewed against the job specifications before assigning a replacement.
