Military-industrial complex (MIC) is a concept commonly used to refer to policy relationships between governments, national armed forces, and the industrial sector that supports them. These relationships include political approval for research, development, production, use, and support for military training, weapons, equipment, and facilities within the national defense and security policy. It is a type of iron triangle.
The term is most often played in reference to the military of the United States, where it gained popularity after its use in the farewell address speech of President Dwight D. Eisenhower, though the term is applicable to any country with a similarly developed infrastructure. (see more http://en.wikipedia.org/wiki/Military-industrial_complex)
