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. In 2005, the Commander, United States Strategic Command (USSTRATCOM) was designated as the lead Combatant Command for the integration and synchronization of DoD's efforts in support of U.S. government "Combating WMD" objectives. It was at this time that the SCC-WMD was co-located with DTRA. The Combat Command designation was changed again in 2017, when responsibility was moved to U.S. Special Operations Command (USSOCOM). In 2012, the SJFHQ-E was relocated to the DTRA/SCC-WMD headquarters at Fort Belvoir. This centralized the DoD's Combating Weapons of Mass Destruction operations, a move recommended in the 2010 Quadrennial Defense Review. On September 30, 2016, the Joint Improvised-Threat Defeat Agency (JIDA) became part of DTRA and was renamed the Joint Improvised-Threat Defeat Organization (JIDO) in accordance with the 2016 National Defense Authorization Act (NDAA). In Section 1532 of the NDAA, Congress directed the DoD to move JIDA to a military department or under an existing defense agency. DTRA requested a base budget of $1.2 billion for fiscal year 2017 (FY17). The three other components of DTRA's overall resource portfolio include executing the $361 million Science and Technology portion of the DoD Chemical and Biological Defense Program (CBDP); managing the CBDP's remaining $833 million budget; and $408 million in overseas contingency operations funds requested by the JIDA (now JIDO). These additional amounts bring DTRA's total resource portfolio to approximately $2.8 billion for FY17. Responsibilities Destruction of Soviet arms After the end of the Cold War, DTRA and its predecessor agencies implemented the DoD aspects of several treaties that assist former Eastern Bloc countries in the destruction of Soviet era nuclear weapons sites (such as missile silos and plutonium production facilities), biological weapons sites (such as the Soviet biological weapons program), and chemical weapons sites (such as the GosNIIOKhT) in an attempt to avert potential weapons proliferation in the post-Soviet era as part of the Nunn–Lugar Cooperative Threat Reduction program. Other treaty responsibilities DTRA is responsible for US reporting under the New START Treaty and the Intermediate-Range Nuclear Forces Treaty. DTRA is also responsible for reducing the threat of conventional war, especially in Europe, by participating in various arms control treaties to which the United States is a party, such as the Conventional Forces in Europe treaty, the Treaty on Open Skies,
