Overall this is a very violent movie, not just graphic violence but graphic in tone as well.
American soldiers eventually start fighting each other, due to their frustration. One soldier grabs a knife and attempts to kill another soldier, but his men tells him to calm down.
An American soldier's corpse is seen pinned to a tree with a moderate amount of blood visible.
An American soldier holds a gun to a Vietnamese girl's head in front of her family, but another soldier punches him in the face and the two fight until a third soldier breaks them up. Both bleed.
A man is blinded by shrapnel and covers his face screaming before a Vietnamese soldier comes up and unloads a gun on him.
A man is wounded by an explosion nearby, another man cuts into him with a knife to rip the shrapnel out.
Two men are blown to pieces after an airstrike is called on them.
A man is shot in the lungs and has trouble breathing while oozing blood. It is implied that a man is piecing his internals back in. Scene isn't graphic.
A man runs away and another man shoots him from a distance, killing him.
A brief scene of taking wounded men back to an Aid zone, though it is a short scene there are many sitings of wounded men, dead mutilated bodies, and medic is covered in blood.
An unarmed Vietnamese woman is shot in the head at close range as her husband and daughter look on in horror; we see blood spray from the wound, very graphic.
A Vietnamese soldier is taunted before having his head bashed in with a rifle butt. This is implied and offscreen and quite unrealistic as only quiet thuds heard. Some blood sprays onto the perpetrator's face, but this is not graphic. The whole scene is intense, disturbing, and horrifying however.
One soldier loses a hand when another soldier accidentally throws a grenade in his direction (some blood is shown). Two men are in a Vietnamese bunker when it explodes, and one emerges with no arms.
One soldier has his leg blown off by a booby trap (the injury is not shown).
In one battle scene, a soldier runs away from his foxhole, but runs into a tree and is then bayoneted by a Vietnamese soldier.
It is implied that a young Vietnamese girl was raped by American tropps. This is not seen however, although you do see a group of Americans soldiers crowded around laughing while she is crying.
