My father, Jack Gardner, enlisted on March 14 1939 at 18 1/6th (that's how it is put on his paperwork) years old in Austin TX. He was assigned to the 111th Quartermaster Regiment Co. B to do administrative work. He attended the Army Administration School and advanced in rank to Technical Sergeant and was assigned as a Personnel Sergeant to that unit. He also qualified as a rifle marksman--no doubt as part of basic training. On November 22 1940 he was inducted into active service, having previously been in the National Guard. Interestingly, because he was already in the military he never had to sign up for selective service (the draft). It appears he remained in Texas as part of that QM regiment until August 16 1942 when he was discharged with 4 years, 15 days of service to be commissioned as a 2nd Lieutenant the next day. He lost no time to AW 107 (eg., had no disciplinary action as an enlisted). He was sent to Grinnell Iowa for OCS where he was commissioned on 14 April 1942. He was then sent to 6th Army HQ at the Presidio, San Franciso, CA where he served as a cryptanalytic officer MOS 96.00 on 14 April 1943. I assume the year in between he was being trained somewhere but I don't know where. He remained there until 16 April 1945 when he was discharged from active service while in McGaw General Hospital Walla Walla WA for some unspecified physical disability (I'm pretty sure it was something related to a heart murmur) serving 2 years 11 days. Afterwards, he returned to the same job as a civilian, retaining his commission as an inactive reservist and was later promoted to 1st LT on 16 Jan 1947. He continued to work as a civilian for the Department of Defense into the 70's in much the same role retiring from civil service in the mid 70's.
