701 Reel Unit Operator

Appendix B identifies SSN 701 as “Reel Unit Operator” under AR 615-26 of September 1942 and its supplements, and lists SSN 641 as a suggested conversion. This was not an automatic replacement: each affected Marine’s qualifications had to be reviewed against the job specifications before selecting the appropriate classification.
