The idea that the tools of social science in general and anthropology specifically can provide military commanders with valuable insights on the "human terrain" is not unreasonable in itself. What I suspect is often overlooked is the reality that good field work takes a great deal of time. Even a very good anthropologist cannot walk into a new community, open some sort of intellectual spigot, and produce a stream of valuable insights. A good anthropologist wouldn't even try. Sending social scientists who have not specialized in an area into the field for a few weeks or months and expecting useful information to emerge is generally going to be futile, especially in a security environment that requires the people doing the study to have military escorts, restricts their time and movement, and makes the community slow to trust and reluctant to provide accurate information.
