Vietnam, because of historical and geographical
factors, has an extrordinary number of different religious influences,
including Animism, Buddhism, Hinduism, Confucianism, Christianity and
several indigenous belief systems such as Cao Dai.
This guidebook, published by the US military, is a reference
about this subject, compiled on the cusp of the Vietnam war.
It includes quite a bit of cultural and background information
about Vietnam, statistics about numbers of adherents, as well as
a guide to cultural sensitivity which may still be of use.
This is a valuable resource about this fascinating topic.
It also implicitly tells quite a story about the US military's
attempt to win Vietnamese 'hearts and minds'.
