Wonderful history in your family.
A grand-niece of mine, who is now about 27, attended a Naval Academy summer program while she was in 7th grade. She made it through the PT, and she enjoyed the experience, but she did not pursue any subsequent military options. Probably looked good on her transcript when she attended college, though.
Best of luck to Benjamin. Blessings to your family.
It usually is a good idea for women to steer clear of the service. The problem is that so few young men are man enough to serve in any capacity causing severe personnel shortages. This is no different than the problem Rome had; when young men won’t stand to defend their nation. It is sad.
