National War College
The National War College (NWC) of the United States is a school in the National Defense University.
It is located in Theodore Roosevelt Hall in Fort Lesley J. McNair, Washington, D.C., the oldest Army post still active today. It was officially established on July 1, 1946 as an upgraded replacement for the Army-Navy Staff College, which operated from June 1943 to July 1946.
According to Lieutenant General Leonard T. Gerow, President of the Board which recommended its formation, "The College is concerned with grand strategy and the utilization of the national resources necessary to implement that strategy... Its graduates will exercise a great influence on the formulation of national and foreign policy in both peace and war...."
Most mid-level and senior military officers take a course of study at the War College in preparation for higher staff and command positions.
Institute for National Strategic Studies
INSS is the primary research institution of National Defense University. Its fellows conduct research regarding national security policy and design and conduct strategic gaming exercises. Because its goals for United States strategy aim for minimal conflict, the staff frequently hosts and visits the military research institutes of other nations, most importantly those of the People's Republic of China, the Republic of China, Japan, and the Russian Federation. The meetings are meant to foster collaboration and understanding.
To provide a forum for the reasearch conducted, INSS also publishes Joint Forces Quarterly, a magazine that covers the specific issues related to national security and military strategy. Similarly, since the institute's establishment in 1984, the fellows have published hundreds of scholarly papers under the NDU Press imprint as well as other specialized journals and fellows frequently publish in the op-ed section of many papers.
The director of the institute, Dr. Stephen J. Flanagan is also the vice president of the university for research.
