Staff sergeant in CH-21 · Converted to 67S40, effective 1965
The article’s prose example maps old MOS 676.60, staff sergeant in CH-21, to 67S40. The scan was visually checked: the third character is the letter S. Change 15 directed active-duty personnel conversion during 1–25 July 1965; effectiveTo is conservatively recorded at year precision rather than assigning one uniform individual conversion date.
