0188 Operator, jackhammer

Operator, jackhammer · Converted to 5729, 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The instrument prints no field-wide rescinded-code list; only its explicit appendix T/O&E position conversions are asserted here. Jackhammer-operator and laborer positions convert to pioneer MOS 5729. The 2 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.

Duty Soldier II · Split into 4745, 4812, effective April 29, 1949

Paragraph 6 restricts this SSN in Infantry use but does not rescind it Army-wide. Paragraph 6 directs ammunition-bearer or filler use to 4745 for light-weapons duties or 4812 for heavy-weapons duties; the appendix visibly instantiates 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.
