814 Operations NCO

Appendix B lists SSN 814 as “Operations NCO” in both the September 1942 regulation and supplements column and the June 1944 tentative-manual column, with “See also 791” referring to those earlier titles. Its June 1945 title is “Operations Clerk, Aviation,” but the entry does not establish a cancellation, a formal rename, or a fixed replacement by SSN 791.

Documented history

Operations NCO

June 1945 is the manual’s publication date; no effective date is given for a transition involving this entry.

  • The reference to SSN 791 required review of the individual’s qualifications against the job specifications, not automatic conversion.
  • The 1945 title describes the wartime classification, not a modern occupation with the same code.
Source extraction notes

Predecessor title from the June 1944 tentative-manual column: Operations NCO. Suggested conversions/remarks, as printed: *See also 791. 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: Operations Clerk, Aviation. 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.
