  • The record does not establish an Army-wide cancellation of SSN 0590.
Source extraction notes

The instrument prints no field-wide rescinded-code list; only its explicit appendix T/O&E position conversions are asserted here. Orderly positions convert to pioneer MOS 5729. The 4 position-level source assertion(s) are collapsed into this one canonical predecessor event, preserving first-source successor order. Personnel MOS conversion is effective 1 February 1950; the appendix's T/O&E position amendments took effect 7 November 1949. The predecessor remains in the SSN namespace; successors are numeric MOS codes.

Orderly

Listed Orderly positions coded SSN 0590 were converted to MOS 4745 or MOS 4812, depending on the organization. These were changes to specified positions, not a blanket replacement of SSN 0590.

  • SSN 0590 was not included in the regulation's cancellation or restricted-use lists.
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. Orderly positions convert by organization to 4745 or 4812. 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.
