Insurgents’ intelligence network and practices during the Greek Civil War

John N. Gentry argues that Violent Non-State Actors, such as insurgencies or terrorist groups, use intelligence in three ways. First and foremost, they employ intelligence to plan physical military attacks and to protect themselves from penetration and attack by government forces. Secondly, they use counterintelligence in order to ensure the survival of the insurgency and preserve the faith of their members by enforcing ideological discipline. Finally, they use information operations to shape their operational environments. This article seeks to determine what type of intelligence the Greek insurgents employed during the civil war and whether this insurgency fits Gentry’s model.
