Belt buckle WRONG, Seal Trident, looks like Shave Tail with First Lt bars, WAY too much fruit salad, can't get enough magnification, but his cover emblem might be enlisted. They used to prosecute for cr@p like that, and if he is a Jarhead, he should be shot!! Regards, Bruce.
P.S. Looked again and you were right, combat, a freekin' Silver Star!! And in front of it was what looks like the gold lifesaving medal, but I can't tell. Also notice that the guy passing him to the right looks ready to lay into him. I hope he did!!
