Documented history

Parachutist/Combatant Diver Marine · Converted to 8026, effective 2006

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.
