Make sure he signed up for the GI Bill & College Fund. Also, when he gets to his permanent duty station he needs to find the satellite college campus on base. Most if not all bases have this. The Navy will give him tuition assistance to pay for school and it won't count against his GI Bill or College Fund $$$. There's no reason why he can't get a minimum of an Associate's during his 1st tour. Since he's going in to aviation field I would highly recommend Embry Riddle. They're a top-notch institution and have satellite campuses as well as online classes. They will also give credit for his Navy schools.
