It happened to one of our instructors when I was at NTC Great Lakes int he Navy. He was a FC1 (E-6) up for Chief (E-7). He got busted for fraternizing with a student and lost a stripe for it (busted to E-5). Doesn't sound like much of a punishment, but it set him back 6 years in his career. He had to wait 3 years before he was eligible for E-6 again, then 3 years before he go up for Chief again.\n\nFraternization does not need to be sexual. This was a teacher and student hanging out having some beers after school.
