The Defense Threat Reduction Agency (DTRA) is charged with reducing the present threat to the United States and its allies from weapons of mass destruction (WMD) and preventing future threats. DTRA is creating the intellectual infrastructure for a new approach to deter and counter the worldwide proliferation of WMD. DTRA reviews licenses for the export of U.S. technologies that could be used to support the production and delivery of WMD or conventional weapons to ensure that the transfers are consistent with U.S. national security interests. It implements the Cooperative Threat Reduction program, which assists former Soviet Union countries in reducing their WMD infrastructure and provides verifiable safeguards against WMD proliferation. DTRA conducts force protection vulnerability assessments designed to protect military and civilian personnel and their families from terrorist acts. The Agency leads DoD efforts to support operational forces and develop field systems to counter WMD proliferation.
