Yes, if you want to put it that way. DH had to have his parents do the same back in '75. The same is (was?) true for enlisting in the service. Has something to do with signing a legally binding contract before 18, being a legal adult.A quick google search answers this, but yes he will be totally fine. If I am fortunate enough to receive an appointment next year, I'll be 17 going in. Maybe someone more knowledgeable than I can answer this fully, but my understanding is that a parent has to sign over custody or permission if the cadet is 17 when they report.
