233 Switchman, Railway

Appendix B identifies SSN 233 as “Switchman, Railway” in the AR 615-26 September 1942 and supplements column, and suggests SSN 033 as a possible conversion. This was not an automatic replacement: the individual's qualifications had to be reviewed against the manual's job specifications.
