Overwhelmed Dad. In the end there will be one Academy your DS would like better. And he will lean on one more than others. It may not be as clear now but it will become clear soon. I agree with FMHS-79. Pick the service first then pick the Academy! They are all different. However, Navy is the service that offers the most diverse community to pick your career: Aviation, Ship, Sub, Land/Aviation - Marine, Cyber/Intel (proportionately small number direct Commissioning). My kid was all Army and Air Force throughout his youth. Then he chose Annapolis. You just never know. So for now go with your son’s strongest first impression. Your DS should also apply to USMMA since he is fine with any service. At USMMA you can commission into any service. And you can receive Nom from any district MOC in your state so you can get 2 Noms. Good luck.
