319 Tractor Mechanic

Appendix B lists SSN 319 as Tractor Mechanic in the September 1942 AR 615-26 and supplements column, with an asterisk linking that earlier title to “See also 014.” Engineer Equipment Mechanic appears under 319 in both the June 1944 and June 1945 title columns, but the reference to 014 does not establish an automatic conversion, cancellation or fixed replacement.

Documented history

Tractor Mechanic

No effective date is given for this entry. June 1945 is the manual’s publication date, not a documented date of conversion or cancellation.

  • The reference to 014 required review of the individual’s qualifications against the job specifications, not automatic reassignment.
  • The June 1945 title describes the wartime classification, not a modern occupation with the same code.
Source extraction notes

Predecessor title from the AR 615-26 column: Tractor Mechanic. Suggested conversions/remarks, as printed: *See also 014. 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: Engineer Equipment Mechanic. 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.
