Basic Marine with Enlistment Guarantee
The manual was effective May 15, 2006, but personnel-system implementation was explicitly deferred, with no specific implementation date given for this conversion. July 20, 2006, is the announcement's publication date, not the conversion date.
Source extraction notes
The cited source prints the MOS code but not its occupational title; no title was inferred. Enlisted MOS moved from reporting category 9000 to miscellaneous-requirements category 8000. The manual is effective 2006-05-15, but personnel/HRDP implementation is explicitly deferred, so effective_to is null. No row-specific effective date is printed; year-only precision reflects the 2006 manual transition.
