920 Control System Repairman, Light Antiaircraft

The June 1945 Marine Corps manual lists SSN 920 under the earlier title “Control System Repairman, Light Antiaircraft” and suggests SSN 918 as a possible replacement. This was not an automatic conversion: each affected individual's qualifications had to be reviewed against the manual's job specifications.
