978 Ordnance Supply Clerk

Appendix B lists SSN 978 as “Ordnance Supply Clerk” in the June 1944 tentative manual and “Ordnance Stock Man” in June 1945. Its starred “See also 580” refers to the earlier title, but does not establish conversion to SSN 580 or another fixed successor.

Documented history

Ordnance Supply Clerk

June 1945 is the manual's publication month; no effective date is given for a change involving this entry.

  • The differing titles do not by themselves establish a formal rename or cancellation.
  • Any suggested reassignment required review of the individual's qualifications against the job specifications, not automatic conversion.
Source extraction notes

Predecessor title from the June 1944 tentative-manual column: Ordnance Supply Clerk. Suggested conversions/remarks, as printed: *See also 580. Asterisks bind the suggestions to the correspondingly marked earlier title, not to an unmarked present-title meaning. The Present Title column is the manual's June 1945 meaning: Ordnance Stock Man. It is not a present-day MOS equivalence. This is a cross-reference or instruction to review the job specification, not an explicit fixed replacement or proof of cancellation. The table gives no row-level calendar effective date. June 1945 is the manual publication date, not an inferred individual conversion date.
