891 Radio Mechanic B

Appendix B identifies SSN 891 as “Radio Mechanic B” under AR 615-26, September 1942 and supplements, and lists SSN 774 as a suggested reclassification. Reclassification required reviewing the individual’s Qualification Card against the job specifications, rather than automatically converting 891 to 774.
