 Toward the end of the film, when the reinforcements arrive after the  battle, Rhah (Francesco Quinn (qv)) is shown reaching into a dead  VCs breast pocket and pulling something out which he keeps, while  looking around nervously. The item he is removing is heroin, which  VC soldiers carried for use as a painkiller. This act was done by  many US troops who developed the addiction. It also implies that  Rhahs mystical quality is probably a symptom of a larger problem.
