Documented history

Heavy Weapons Crewman

The position conversions took effect on 29 April 1949: paragraph 8a explicitly made them effective on the regulation's date.

  • The successor for a particular soldier cannot be determined from the old code alone.
Source extraction notes

Paragraph 5 rescinds this SSN. Heavy-weapons platoon/section/gunner positions convert to 1812, 2812, or 4812; an appendix first-sergeant exception converts to 1745. 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.
