Title not stated in source
The deletion date is not stated. 30 June 1945 is the publication date of Change 2, not an established effective date for the deletion.
- Appendix I does not state the deleted specialty's title.
- Promotion requiring no additional basic occupational knowledge leaves the MOS unchanged; supervising a group requiring knowledge of more than one MOS can result in acquiring a new MOS.
- Paragraph 10's example codes illustrate assignments based on actual duties, not universal successors to SSN 652.
Source extraction notes
Appendix I deletes SSN 652 but provides no explicit SSN successor code. Printed directive: "(See par. 10.)" No paragraph reference, ASTP symbol, or generic gun-crewman instruction was inferred into the SSN namespace. The table does not print the deleted specialty title, so the neutral title placeholder is used. The row-level deletion date is unstated. The citation dates Change 2 to 30 June 1945; that publication date is not an effective deletion date.
