030 Boiler Maker

The June 1945 manual lists SSN 030, Boiler Maker, under the earlier AR 615-26 titles from September 1942 and supplements, and suggests SSNs 024 or 201 as alternatives. These were not automatic conversions: each Marine’s Qualification Card had to be reviewed against the job requirements before selecting a replacement.
