Member, the President’S Own, United States Marine Band · Converted to 5511, effective 2006
The cited source prints the MOS code but not its occupational title; no title was inferred. Enlisted MOS moved from category 8000/9000 to a regular occupational field. 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.
