The Strategic Studies Institute is the U.S. Army's institute for geostrategic and national security research and analysis. The Strategic Studies Institute conducts strategic research and analysis to support the U.S. Army War College curricula, provides direct analysis for Army and Department of Defense leadership, and serves as a bridge to the wider strategic community.
The Strategic Studies Institute is composed of civilian research professors, uniformed military officers, and a professional support staff. All have extensive credentials and experience. SSI is divided into three components: the Strategic Research and Analysis Department focuses on global, transregional, and functional issues, particularly those dealing with Army transformation; the Regional Strategy Department focuses on regional strategic issues; and the Academic Engagement Program creates and sustains partnerships with the global strategic community. In addition to its organic resources, SSI has a web of partnerships with strategic analysts around the world, including the foremost thinkers in the field of security and military strategy. In most years, about half of SSI's publications are written by these external partners.
