Water Safety/Survival Instructor
The manual was effective May 15, 2006, but implementation in personnel systems was explicitly deferred. The conversion belongs to the 2006 classification transition; no specific personnel implementation date is given.
Source extraction notes
The cited source prints the MOS code but not its occupational title; no title was inferred. Enlisted MOS moved to new occupational field 09, Training. 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.
