The movie was typical Hollywood in its ending for sure.....nothing at all like the real events.
The LZ X-Ray fight was a distinct event from the subsequent ambush and destruction of the Battalion that was moving by ground towards LZ Albany.
That event could very well be its own movie.
In my view, the best Vietnam Movie is "Hamburger Hill"......followed perhaps by "More American Graffiti".
Books I recommend....
"We Were Soldiers Once....And Young" by Moore and Galloway
