818 Railway Transportation NCO

Appendix B lists SSN 818, Railway Transportation NCO, under the earlier AR 615-26 title and suggests SSNs 069, 266, 379, 573, or 574 as possible replacements. These were not automatic conversions: each Marine’s Qualification Card had to be reviewed against the job specifications to determine the appropriate specialty.
