"These cards can be used in many different ways, but they are designed as ―fillers�- to be taken out of your ACU pocket and used between tasks or waiting for the next training to begin. Soldiers must understand how vital culture is in accomplishing today's missions. Military personnel who have a superficial or even distorted picture of a host culture make enemies for the United States. Each Soldier must be a culturally literate ambassador, aware and observant of local cultural beliefs, values, behaviors and norms."
