Good Morning!
 
American soldiers were prepared for various war scenarios. The Vietnamese model, however, did not allow for the development of the tactics learned in the academy, since the country's jungle scenario was new to the soldiers of the United States of America. Thus, one of the oppositions made was the ineffectiveness of the American presence on Vietnamese soil, since they did not have the knowledge of the terrain necessary for an adequate victory.
