734 Half-Track Driver

Appendix B identifies SSN 734 as Half-Track Driver in the September 1942 regulations and June 1944 tentative manual, and suggests SSN 245 or 610 as alternatives. These were not automatic conversions: each Marine's Qualification Card had to be reviewed against the job specifications before selecting a replacement.
