The technology growth and widespread expansion in the number of nations, particularly among third world countries, possessing or acquiring nuclear, biological, and chemical (NBC) weapons have dramatically altered the NBC threat of U.S. military forces. This worldwide proliferation of an NBC offensive capability indicates that U.S. forces must have an integrated NBC defense which includes NBC sensors on ground vehicles in order to operate and survive on the future multi-threat battlefield. Critical to developing and implementing a strong operationally supportive NBC defense posture is the requirement to integrate NBC effects into wargames and simulations. This project will perform a worldwide market survey and technology review to evaluate existing military, commercial, and developmental NBC sensors for use on U.S. Army ground vehicles. Laboratories, military equipment compendiums, subject matter experts, information analysis centers and other on-line data bases will be utilized. The feasibility of imbedding and/or interfacing NBC models into existing force-on-force models will be assessed. These results will provide the framework for developing a simulation that accurately models NBC insults and their effects against both system/crew and a force within existing COEA force-on-force models.
