Source extraction notes

Predecessor title from the AR 615-26 column: Artillery Mechanic, Base Defense. Suggested conversions/remarks, as printed: *See also 839, 913. 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: Antiaircraft Artillery 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.
