I was reluctant to answer up because I didn't have a new movie to come up with after I answered.
It is Taking Chance. If you haven't seen it, I would highly recommend it. It seems most OIF movies are focused on how people always come back from there in one of two ways: dead or screwed up in the head. I guess no one wants to make the movie about the guy who goes as an infantry officer, does a lot of good and worth while things and comes home feeling good about his contribution to a better Iraq and safer America. I suppose that isn't very Hollywood.
Having said all of that, the fact that a Marine died in combat is key element in the story. The story, however, is not the death of the Marine, but how the Marines strive to honor those in our ranks who have paid the ultimate price. Kevin Bacon plays a Beltway (i.e. in the Washington D.C. area) Marine who volunteers to be the CACO (Casualty Assistant Calls Officer) for a young Marine who has died in Iraq. A CACO is the one who not only must bear the burden of informing the family but also helps them sort out the final affairs for his final pay and benefits, funeral, etc. It is no easy task - even if the family is not hostile to the bearer of the bad news. (I have heard of calls where the family [wife or parents normally] is sad, angry, violent, or even sometimes happy. I guess not all marriages are meant to be.) The movie is very well done and, as Vee points out, very emotional.
I'll come up with something new tomorrow.
