Minimal, one scene with the couple in bed embracing. You see his bare chest, she has her top on.

Descriptions of Vietnam atrocities, mutilation of corpses by US soldiers and Vietnamese military personnel.

The F word, shit, and bullshit used liberally throughout the course of the movie

A lot of smoking cigarettes, and some scenes with people drinking alcohol. No real clear scenes of intoxication.

Nothing frightening except for the descriptions of the war.
