Medal of Honor recipients get automatic appt if they are qual. Seeing as all of the medal winners that would be eligile due to age req. parents are dead, they def. deserve it. I believe the children of black hawk down are the only ones eligible right now. I know that one did not have any chilldren since they lived on our block and the Seal commander was our neighbor who went in, the media was all over are neighborhood (Wife of the Seal did not know until sev. mos. later when he received the Silver Star from Perry...so top secret, that the wife didn't know what the medal was even for until the read the citation, she thought they were going there just to do some bus., after he got clearance he called at the hotel and said you need to bring the kids and get over to the Pentagon, she walked in and there was Perry)
As far as Purple Heart I am almost 100% sure that gives no weight. Remember a Purple heart is a whole different world in medals. Many survivors have one (no offense, I am sure they deserve them and should be proud), however, the Medal of Honor winners are typically given posthumeously (last one I believe was in 2005 ---I think the oldest would be a pre-teen right now)
B4 him I believe it was the black hawk incident and as I said the seals that went into recover their bodies did not get a Medal of Honor, although a Silver Star is special in its own
Also even if they gave it for purple heart, I am sure you would have to be a dependent. Maybe you know someone who knew someone whose father got a purple heart and they got into the academy...my guess would be that it wasn't the purple heart, but instead a Pres. nom
