Gustav Hasford writes in his semi-autobiographical novel ''The Short-Timers'' (the basis for ''Film/FullMetalJacket'') that an audience of Marines was roaring with laughter when they saw the film in Vietnam. Similarly, war journalist John Pilger said about the film: "I had just come back from Vietnam, and I couldn’t believe how absurd this movie was. So I laughed out loud, and I laughed and laughed."
* SuspiciouslySimilarSong: A choral arrangement of "Ballad of the Green Berets" used at the beginning.
