Documented history

Intelligence

The position changes took effect on 7 November 1949. Personnel specialty conversion took effect on 1 February 1950, rather than on the earlier date.

  • This establishes conversion of the specified positions, not Army-wide cancellation of SSN 0631.
Source extraction notes

The instrument prints no field-wide rescinded-code list; only its explicit appendix T/O&E position conversions are asserted here. Intelligence positions convert to combat engineer intelligence under MOS 1729. The 6 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.

Intelligence NCO

In Infantry use, SSN 0631 (Intelligence NCO) was restricted, with intelligence chief, intelligence sergeant, and intelligence specialist positions assigned to MOS 1761. Reconnaissance scout and observer positions were assigned to MOS 4761 instead.

Under paragraph 8a, the changes to authorized unit positions took effect on 29 April 1949, the date of the regulation.

  • This restriction did not abolish SSN 0631 Army-wide.
Source extraction notes

Paragraph 6 restricts this SSN in Infantry use but does not rescind it Army-wide. Paragraph 6 and the appendix assign intelligence-chief/sergeant/specialist duties to 1761 and reconnaissance-scout/observer duties to 4761. 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.
