Cooperative Security is defined as the set of continuous, long-term integrated, comprehensive actions among a broad spectrum of U.S. and international governmental and nongovernmental partners that maintains or enhances stability, prevents or mitigates crises, and enables other operations when crises occur. Military activities undertaken in support of Cooperative Security might include security assistance training, security cooperation activities, mil-to-mil senior leader and staff talks and exchanges, regional cooperation efforts, bilateral and multilateral exercises, and formal arrangements for the use of facilities, basing, or transit of forces. (Military Contributions to Cooperative Security Joint Operating Concept, 2008)
The U.S. government, U.S. allies, and international and nongovernmental agencies conduct a wide range of activities to prevent the proliferation of materiel or technologies associated with the development and acquisition of nuclear, biological, or chemical weapons. The U.S. military participates in these international efforts by supporting arms control efforts, conducting counter-WMD operations and exercises with other nations, providing security assistance, building coalitions, and promoting interoperability for counter-WMD operations. DoD supports the Proliferation Security Initiative through WMD interdiction exercises and operations with coalition countries. By strengthening our partners and allies, adversaries considering the use of WMD are deterred and the burden on U.S. military to respond to overseas CBRN incidents is decreased.
