Corrected entry: When we see the gravestone of Wilson, it doesn't match that he was 19 years old when killed. According to his headstone, he was born in November of 1948 and killed in October of 1967 so he would have been 18, not 19 as stated by his father.
Corrected entry: Kovic mentions on the beach that he is into his second tour in Vietnam, yet he does not wear the Combat Infantryman's Badge at any time on his uniform.
Correction: The CIB is awarded to Army and Special Forces personell, not to the Marines.
Correction: He was a month or less from turning 19 (it could have been a couple days), it's definitely close enough to call him 19.
