According to the Office of Medical History , this was a "Discharge for the Convenience of the Government". The language on that page is a bit convoluted, and I'm not sure exactly if it summarizes all the provisions of War Department Circular 395, but it seems to say people who didn't know much English and who were not "useful" to the Army (in a certain technical sense) could be discharged this way. Another (more likely) possibility is that, as a skilled lathe operator, the military felt his skills were more valuable in a factory producing war material.
