The IDF refused to grant the request of a young man who asked to serve as an army instructor because it's a position usually identified with women. "Males don't train," was the curt answer 17-year-old Yochai Eran received. Ironically, Eran requested the position because the army told him he'd be good at it. His medical profile -- a system the army uses to identify a candidate's suitability for various positions -- indicated he would excel at the position.
