The Defense Threat Reduction Agency (DTRA) is an agency within the United States Department of Defense and is the official Combat Support Agency for countering weapons of mass destruction (chemical, biological, radiological, nuclear, and high explosives). DTRA's main functions are threat reduction, threat control, combat support, and technology development. The agency is headquartered in Fort Belvoir, Virginia. DTRA (and its co-located partner organizations the SCC-WMD and SJFHQ-E) employ approximately 2,000 civilians and uniformed service members at more than a dozen permanent locations around the world. The majority of personnel are at DTRA headquarters on Fort Belvoir, Virginia. Approximately 15% of the workforce is located on Kirtland Air Force Base and the White Sands Missile Range in New Mexico, and the Nevada National Security Site (formerly called the Nevada Test Site), where they do testing and support the U.S. military's nuclear mission. Another 15% of the workforce are stationed in Germany, Kazakhstan, Azerbaijan, Uzbekistan, Georgia, Ukraine, Armenia, Kenya, South Korea, Japan, and Singapore. DTRA also has liaisons with all of the U.S. military’s Combatant Commands, the National Guard Bureau, the FBI and other U.S. government interagency partners.
