647 Radio Repairman, Aircraft Equipment

Appendix B identifies SSN 647 as the earlier “Radio Repairman, Aircraft Equipment” classification and suggests reclassification to SSN 174, not a split between 174 and 649. This was not an automatic conversion: each affected Marine’s Qualification Card had to be reviewed against the manual’s job specifications.
