Wow. A teenager? A teenager? A 13 year old? Yes, he was mentored by a retied general and just like ROTC...he was a captain, put in charge of others at the school. It was basic training, with guns and all. He came out an officer and gentleman.
So, TRUMP...rejected your sister. Not up to his standards. lol. She threw herself at him and he had NO USE for someone unattractive? It is becoming clear now. 
-------------------
Teen-agers are NEVER Commissioned Officers by Rule, in any branch of Service at any time, yet why?
Because that would permit 13 to 18 year olds to command soldiers 20 years and older, a dangerous situation.
Do you ever reflect, even for a second, on a single word you blather or simply eternally run off at the mouth???
Trumpty Dumpty was sent to the NY Military Academy, a reform school for the behaviorally needy.
HE WAS NEVER AN OFFICER/GENTLEMAN, SIMPLY A SCHOOL BOY REQUIRING DISCIPLINE WHICH IS
WHY HIS MOTHER SENT HIM THERE. HE WAS A CADET NEEDFUL OF DEVELOPING HIS MIND, CHARACTER
AND LEADERSHIP TRAITS. GUNS HAD NOTHING TO DO W/HIS SCHOOLING. GOT It !!!!!!!!
