Actually it is his responsibility to find the regulations. If he was going to be eligable for the draft then it was his job to find out ther rules, not the Army's. He is a young leader, a west point graduate. The Army has invested A LOT of money into him with all the training he has recieved. Don't forget that in addition to how much it cost the Army to send him through west point he had additional training as well. He could very well be Airbone and Ranger Qualified. Those schools are not cheap. If he could buy out his contract, I would be it would be in the 500k range or more.
Sorry you have to miss this oppertunity, but its time to fulfill your committment to the country. The Army will try to work something out for him, but until then he is obligated to report. Time to fullfill that promise you made.
Sorry, Military Service is far greater than freakin football.
