I was just so happy that my wife suggested we see this in the theater that I gave it a pass, but since I knew the units involved I knew at the beginning that the old man with the Screaming Eagle pin on his windbreaker had to be Ryan since the Rangers were all part of one of the Ranger Battalions and not part of the 101st Airborne Division. it was never a surprise who he was.
BTW there were 2 Ranger Battalions that existed in June 1944. One of those Battalions went up Pont Du Hoc and one went on Omaha Beach (further BTWs the 2 AMERICAN beaches were Utah and Omaha, the Brits and Canadians had Gold, Sword and Juno beaches). The way I figure it Hanks best fits a guy named Major Brown who took a Company of Rangers into Normandy on Omaha Beach section Red Dog One. By the time the movie's Saving Private Ryan part would have taken place Brown's company was down to 11 guys.
