Notes & Sources
- GSCM is the paygrade E-9 merged senior rating over the Gas Turbine System Technician service ratings GSE (Electrical) and GSM (Mechanical); the GSE and GSM chapter career patterns show GSCM above GSCS (E-8) and the service-rating ladder.
- The identifier does not record whether the holder's background is GSE or GSM; verified duty evidence is published on the GSE and GSM pages.
- Because the duty specialty cannot be attributed to this code alone, occupation-specific skills, career paths and credentials are not offered here.
