The surveyor position converts to instrument-operator MOS 3577, explicitly marked as an Artillery Career Field exception. The 1 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."]
