Just finished it. Powerful. If I were teaching a HS or college course, the film would be an excellent starting point.
As a side note, I am distracted when something is not authentic. The movie starts out in 68 and ends in 69. Throughout, they are wearing the white name tags on their fatigues. I remember making the switch to subdued insignia as we (A Co. 4th Avn. Bn) deployed from Ft. Lewis during the first week of 1967. Maybe the Old Guard at Meyer didn't make the change until later.
Good movie. Something kept me from seeing it when it was released. Can't remember what it was now. Thanks.
