Documented history

Ammunition bearer

The position changes took effect on 7 November 1949. Conversion of incumbents' primary or potential-primary MOS took effect on 1 February 1950.

  • The regulation establishes these position-specific conversions, not an Army-wide cancellation of SSN 0504.
Source extraction notes

The instrument prints no field-wide rescinded-code list; only its explicit appendix T/O&E position conversions are asserted here. Ammunition-bearer positions in the specified Infantry column split by the enumerated billets: squad-leader-assistant, combat-construction-specialist, and demolition-man billets convert to 3729; pioneer/ammunition-bearer billets convert to 5729. The 10 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.

Ammunition bearer

The listed unit positions for SSN 0504 (Ammunition bearer) were converted to MOS 4812 or MOS 4745, depending on the weapon branch they supported. This establishes changes to those positions, not an Army-wide cancellation of SSN 0504.

The conversions took effect on 29 April 1949 because paragraph 8a made the appendix changes effective on the regulation's date.

  • The available text does not specify which supported weapon branch led to 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. Ammunition-bearer positions convert by the supported weapon branch 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.
