my son has had a life long dream to be a MARINE. He had coarctation of aorta heart surgery when he was 12. His heart is corrected. he is an extremely fit young man that plays varsity soccer and basketball. He isn't on medication and doesn't have restrictions. he has been rejected by the MARINES. Is there any chance that when they appeal this decision that it will be approved? just wondered if there are any cases of this in military.(actually any branch of military)?
