Plebe Summer used to have a new 2ndLt or Ensign assigned to each company. They served as an assistant Company Officer. Basically someone to help split up the time with the regular company officer assigned as we all know those are long days 7 days a week. It wasn’t that long ago they had those assigned. They didn’t really ‘train’ plebes. Just a supervisory rule. And of course lots of new officers around teaching sailing and other classes.
