9957 Signal Electrician

Appendix B identifies SSN 9957 as Signal Electrician in the AR 615-26 September 1942 and supplements column and suggests SSN 648 for conversion. That suggestion was not an automatic replacement: each affected Marine’s Qualification Card had to be reviewed against the job specifications.
