 GEOG: The movie supposedly takes place in Vietnam. Besides the  southern yellow pines that make up 95% of the forests, there is an  obvious lack of palm trees and other tropical plants. In addition,  in the beginning of the movie they walk past a water tower with a  red and white checkered paint scheme. This is how water towers are  painted on U.S. military bases in the United States. Forward  operation posts do not build water towers like this.
