0502 Administrative NCO

Administrative NCO · Split into 1268, 1390, 1622, effective March 1, 1950

Paragraph 4 restricts this SSN only in Finance Career Field use; it is not rescinded Army-wide. Paragraph 4 limits this conversion to finance chief-clerk or other disbursing, audit, or fiscal duties and prints the ordered possible set 1268, 1390, and 1622; the appendix's sole 0502 position, on printed p. 38, instantiates 1622. The 1 position-level source assertion(s) are collapsed into this one canonical predecessor event, preserving first-source successor order. Personnel conversion is effective 1 March 1950; the appendix's position-authorizations changed on 5 December 1949. The predecessor remains in the SSN namespace; successors are numeric MOS codes.

First sergeant · Converted to 1729, effective February 1, 1950

The instrument prints no field-wide rescinded-code list; only its explicit appendix T/O&E position conversions are asserted here. The source-visible first-sergeant position converts to combat construction foreman MOS 1729. The 1 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.

Administrative NCO · Split into 1402, 3400, effective December 5, 1949

0502 is not rescinded Army-wide. Paragraph 5 restricts its machine-accounting use and directs 0502 used for supervision of machine-records coding activities to 1402. Most appendix administrative/coding-supervisory positions follow 1402; printed p. 29 line 25 instead maps Control supervisor 0502 to Senior analyst with New SSN 3400. Preserved as a conditional split in first-source order. The p. 29 3400 cell is clear but is a source-visible anomaly relative to both paragraph 5 and the new duty title; it is transcribed, not corrected. Successors are numeric MOS codes; the predecessor remains in the SSN namespace.

Administrative NCO · Split into 1814, 4814, 1761, 4761, 1812, 1745, effective April 29, 1949

Paragraph 6 restricts this SSN in Infantry use but does not rescind it Army-wide. Paragraph 6 assigns operations duties to 1814/4814 and intelligence or reconnaissance duties to 1761/4761. Appendix first-sergeant positions add 1812 and 1745 exceptions. 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.
