In this movie about the gulf war, the marines were superfluous, super-annuated, an appendage like an appendix, anomalous. This is a war movie about marines trained and indoctrinated into perfectly tuned killing machines, they go into war, see hell...then day after day, marching towards the enemy, they never make contact with a living hostile, because every iraqi soldier (and civilian too) has been incinerated already by air power. It's a bummer. The movie is about the insanity of war...in this case, the insanity of Marines at war not getting a single kill. One flips out so badly, that after the war he kills himself.
