Airborne Radio Operator/IN-Flight Observer/Loadmaster-Trainee (Aro/Iro/LM)
The manual was effective May 15, 2006, but personnel implementation was explicitly deferred. No deletion date specific to MOS 7381 was given, so 2006 identifies the manual transition rather than a confirmed implementation date; July 20, 2006 was the message's publication date.
- The record does not establish which specialty, if any, holders of MOS 7381 subsequently received.
Source extraction notes
The cited source prints the MOS code but not its occupational title; no title was inferred. Enlisted MOS explicitly listed as deleted with no named successor. Do not infer a replacement. 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.
