Notes & Sources
- CBCM is the paygrade E-9 Seabee Master Chief merged senior rating across the Seabee ratings; Vol I chapter career patterns place CBCM at the top of every Seabee paygrade ladder and cite NAVADMIN 054/21 for the 'Seabee Master Chief' rating name change.
- The identifier does not record the holder's source Seabee rating (BU, CE, CM, EA, EO, SW or UT); verified duty evidence is published on each Seabee rating page.
- Because the duty specialty cannot be attributed to this code alone, occupation-specific skills, career paths and credentials are not offered here.
