If Kerry's medals do not include the "V" device it would appear that he was no "hero" according to the regulations.
IIRC he got the "V"; citations are on his website (even if they are signed by Reagan's Navy Sec'y).
This could be why Rassman insist they were under fire. If I was in the water after striking a mine and suppression fire was being laid down from several other Swift Boats, I would swear to it too :-)
I will see if I can find the transcript of what the Kerry crew member said and post it!
