Once upon a time, I went from active duty USAF to reserve at the same base (and back to active duty since).
The first day of the first drill, there was a guy who was prior navy. He had sewn his E-6 rank on only one sleeve and it was about 3 inches left of where it should go. Rather than seeing his rank from the side, you could see it when you faced him.
“He had sewn his E-6 rank on only one sleeve and it was about 3 inches left of where it should go.”
Yep, sounds like something I would have done.
