The USMC is heard from.
Jeff, don't stress. The Navy will take care of him, and provide opportunities in many directions.
The only time I recall seeing tears in my Dad's eyes was when he put me on the train to go on active duty. My Mother died the year before, when he was 45 years old, so on the scale of traumatic experiences this must have been huge. (He was a WWII Navy vet). Twenty years later he noted that his seemingly directionless son had made a good choice. But, I had a direction, and anything that did not lead to that was superfluous. Most people simply did not relate to the fact that I wanted to get paid for flying the Navy's airplanes; and would accept some turbulence for the opportunity. Not only did the USN come through on that bargain, they sent me back to get educated in return for a reasonable 20 year commitment. Not the same as getting smarter, of course.
Fair winds, and following seas to your son, and to his parents as well.
