Insubordination?

Rating: Null/10 (20 May 2004)

I Really loved the movie and want to read the book but haven't had a chance. Perhaps one of you who has or has some insight could answer a question of mine.
The only part of the movie that shocked me was when Hoot came back from the "tax-payer funded, Delta safari" and basically showed a really disrespectful attitude toward a superior officer (No, I didn't say HIS superior officer). You know the part I'm talking about. It's when the Captain (I believe his name was Steele) berates him for not having his safety on when they were feasting on the roast boar...mmmm roast boar... I remember saying to myself: "There's no way an ultra-elite member of the military would address a higher ranking officer that way." If only for the example it would give the other men. And I don't give a rat's ass how long it had been from his last meal. Don't misunderstand I really thought the character played by Bana was cool but I had a hard time swallowing that. Your thoughts would be appreciated. Any Ideas?
P.S. Does anyone else have a problem with Josh Hartnett's casting as a Ranger Sergeant. I think Josh Hartnett is a fine actor but he just didn't convince me he was a Sergeant. I could have seen him as one of the Privates though. He just didn't have that Hollywood Sergeant persona...if you know what I mean. He seemed too young and idealistic.
