601 Antiaircraft Gunner

Appendix B lists SSN 601 as “Antiaircraft Gunner” in the September 1942 AR 615-26 and supplements column, and as “Heavy Antiaircraft Gun Crewman” in both the June 1944 and June 1945 columns. The starred instruction “See also 864” applies to the earlier Antiaircraft Gunner title; it does not establish cancellation or a fixed replacement by SSN 864.

Source extraction notes

Predecessor title from the AR 615-26 column: Antiaircraft Gunner. Suggested conversions/remarks, as printed: *See also 864. 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: Heavy Antiaircraft Gun Crewman. 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.
