Source extraction notes
Paragraph 5 rescinds this SSN. Heavy-mortar platoon and squad leadership converts to 1812/2812; gunner and filler positions to 4812; appendix light-role exceptions convert to 2745/4745. 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.
