The war violence in the film is mostly bloodless and rather comical.
Bill's new age beliefs apparently came from a vision after being shot in Vietnam (he falls to the ground, his wound bleeds slowly and he hallucinates).
A group of criminals get into a gunfight (no blood). As Lynn and Bob escape, they accidentally graze an innocent hostage with their car (he has a bloody open cut on his forehead).
As Lynn, Bob, and the rescued hostage head toward more populated area's, an inept security team mistakes people holding gasoline cartons while riding a motorcycle as terrorists, and they end up accidentally firing on another security team in the process, starting a gunfight, with at least one guard getting hit.
Experiments are carried out on goats, with men staring at them so long that they fall to the ground and die.
POW's are tortured by being forced to watch Barney in a small cell.
A soldier is given LSD as an experiment in what could possibly be mind control. The man seems to be having a bad trip, and you then see him walking around the army base naked (bare buttocks from a distance), firing into the air, before shooting himself (offscreen).
