Firebase 9 (1998)

The Viet Nam Conflict may have been the war which hid the threat to mankind even worse than that of war. When casualties not only appear worse than expected, but descriptions of battles sound more hideous than thought possible, the CIA enters the scene to try to get some answers. But, these answers start to come from the most unlikely sources, and explanations of the hell of war start to sound even more like hell than war itself.
