Title not stated in source
30 June 1945 is the publication date of Change 2, not an established deletion date for SSN 653. The effective deletion date is not stated.
- Appendix I does not state the deleted specialty's title.
- Promotion requiring no additional basic occupational knowledge left the MOS unchanged; supervising a group requiring knowledge of more than one MOS could result in a new MOS.
- Paragraph 10's example codes illustrate assignments based on actual specialty, not unconditional replacements for SSN 653.
Source extraction notes
Appendix I deletes SSN 653 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.
