Filler personnel
The unit staffing-table amendments took effect on 7 November 1949. For personnel holding those positions, conversion of their primary or potential-primary MOS took effect on 1 February 1950.
- These changes apply to the listed positions; the regulation does not establish an Army-wide cancellation of SSN 0729.
Source extraction notes
The instrument prints no field-wide rescinded-code list; only its explicit appendix T/O&E position conversions are asserted here. The source uses present SSN 0729 for filler, basic, pioneer, ammunition-bearer, and leadership duties. Filler/basic/pioneer billets convert to 5729; assistant leadership, demolition, and combat-construction-specialist billets convert to 3729; platoon and squad leadership billets convert to 1729. The 62 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.
