Boilerman · Merged into SPCM, effective 1964

Malin/BUPERS source assertion: Established 1964; combination of BT and MM ratings at E-9. Normalized as merged/included. The source explicitly limits this combination to pay grade E-9; it does not assert that lower-pay-grade use of the predecessor rating ended.
