From a neo-Gramscian approach, this research analyses the military institution of the Southern Command as a strategic instrument to U.S. hegemonic maintenance in Latin America. To this end, this article seeks to present an X-ray of the Southern Command from the 2000s, paying attention to its organization, budget structure, and its operating strategies – in particular, in the use of military bases, in the development of ‘partnerships’ for defense and public security, and in the analysis of military education and training in the schools where this institution operates. To conduct the analysis, primary data were collected from documents and electronic sites published by the same institution and by high level institutions, such as the Department of Defense and the U.S. Congress. As a result, we conclude that the Southern Command is characterized by a hybrid mechanism for hegemonic maintenance through a combination that simultaneously encompasses the use of force and consensus.
