Report on the use of the COIN Game at six institutions selected by the DOD: Institute for Defense Analyses, Agency for International Development, The Infantry School, Mobile Command Hq., Air Force Academy, and United States Naval Postgraduate School. Report contains all information on administering the game as well as all six game reports. The COIN Game was a manual game simulating some of the major factors present in the early phases of internal revolutionary conflict. The Pentagon first deployed the manual COIN game as a precursor to a fully computerized version. There are three groups of players in the game: Villagers, Government forces, and Insurgent forces. These forces interact with one another in terms of loyalty declared, information transmitted, and the exercise (or threat of violence). Each group has a different set of objectives, and each starts the game with a different amount of information. The interactions between the groups are observed and recorded by a Control team, and subsequently analyzed and interpreted.
