Messenger
The position conversions took effect on 29 April 1949: paragraph 8a made them effective on the regulation's date.
- The available details do not identify which organizations used each successor code.
Source extraction notes
This code is not in paragraph 5's rescission list or paragraph 6's restricted-use list; only the explicit appendix T/O&E position conversions are asserted here. Messenger positions convert by organization to 4812 or 4745. Repeated position-level change-sheet rows are collapsed into this one canonical predecessor event, preserving first-source successor order. The predecessor remains in the SSN namespace; successors are numeric MOS codes.
