718 Operator, Acetylene Plant

Appendix B identifies SSN 718 as “Operator, Acetylene Plant” under AR 615-26 (September 1942 and supplements) and lists SSN 719 as a suggested conversion. This was not an automatic replacement: each affected Marine’s Qualification Card had to be reviewed against the job specifications before selecting the appropriate classification.
