589 Heavy Antiaircraft Gun NCO

Appendix B identifies SSN 589 as Heavy Antiaircraft Gun NCO in the June 1944 tentative manual and lists SSN 601 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 reclassification.
