They didn’t have computers or laptops back then. Nor one year deployments.

Husky Ed,
Good luck on piecing your father’s records together. Many of the pre-fire (1973) records at the NPRC were burned. I know that my father’s were and I’ve found more of his records when my mother was moved to assisted living and I had to go through the house, than are at St. Louis. If you haven’t been to the NPRC site https://www.archives.gov/veterans/military-service-records . It also has a ‘fact sheet’ that explains which records were destroyed in the fire and which ones survived.
