In 2012, DIA announced an expansion of clandestine collection efforts. The newly consolidated Defense Clandestine Service (DCS) would absorb the Defense HUMINT Service and expand DIA's overseas espionage apparatus to complement the work of corresponding elements at CIA. DCS would focus on military intelligence concerns—issues that the CIA has been unable to manage due to lack of personnel, expertise or time—and would initially deal with Islamist militia groups in Africa, weapons transfers between North Korea and Iran, and Chinese military modernization. The DCS works in conjunction with CIA's Directorate of Operations and the Joint Special Operations Command in overseas operations.
