Promotions - During my World War II service (Nov 42-Aug 45), I was promoted only two times. While a student at MISLS at Camp Savage, after four months, all Japanese American privates were promoted to Technician Fifth Grade (T/5) with pay equivalent to corporal. In Nov 43, when I was assigned to a linguist team of 10 enlisted men and one Caucasian officer graduate, six of the T/5s were promoted to Technician Fourth Grade (T/4) including myself. My next promotion did not come until a month after the war ended in August 1945.
In September, I and the other T/4s on our ten man team were promoted to Technician Third Grade (T/3) and the other three T/5s were promoted one rank. Thus, for the Nisei members of our team, we were not promoted during the nearly two years that we had been overseas during the war.
On the other hand, our team officer, a Caucasian captain, was promoted to major during the course of the war.
