Marine Corps · SSN history

270 Cooper

Appendix B identifies SSN 270 as Cooper under AR 615-26 of September 1942 and its supplements, and suggests SSN 050 for conversion. This was not an automatic replacement: each affected Marine’s Qualification Card had to be reviewed against the job specifications before a suitable classification was assigned.

Documented history

Cooper

June 1945 is the manual’s publication date; no effective date for this suggested conversion is given.

  • The June 1945 Present Title entry is blank, so the record does not establish Cooper as a current Marine Corps specialty at that time.
  • The suggested conversion does not establish that any individual Marine was reassigned to SSN 050.
Source extraction notes

Predecessor title from the AR 615-26 column: Cooper. Suggested conversions/remarks: 050. The table gives no row-level effective date. June 1945 is the manual publication date, not an effective conversion date.
