Source extraction notes

Predecessor title from the AR 615-26 column: Squad Leader. Suggested conversions/remarks, as printed: Appropriate SSN. Chapter I section 13 identifies Appropriate SSN as a deleted classification requiring individual job review because the old SSN does not provide enough information to recommend a fixed substitute. No numerical successor is invented. The table gives no row-level calendar effective date. June 1945 is the manual publication date, not an inferred individual conversion date.
