Source extraction notes

The cited source prints the MOS code but not its occupational title; no title was inferred. PMOS conversion for grades SSGT-GYSGT; 2000-09-30 is the stated no-later-than conversion deadline, not an exact event date. Paragraph 1 covers active, Reserve (SMCR, IRR, IMA and Standby Reserve) and retired Marines, using separate headquarters unit-diary entries under the same no-later-than deadline.
