Defense Criminal Investigative Service

The Defense Criminal Investigative Service (DCIS) was established in 1981 as the criminal investigative arm of the Office of Inspector General, Department of Defense. The Office of the Inspector General along with the DCIS was established under the DOD Authorization Act in 1983 (Pub. L. 97-252). The DCIS protects America’s Warfighters by investigating terrorism; preventing the illegal transfer of sensitive defense technologies to proscribed nations and criminal elements; investigating companies that use defective parts in weapons systems and equipment utilized by the military; stopping cyber crimes and computer intrusions; and investigating cases of fraud, bribery, and corruption to ensure taxpayer dollars are better spent defending our Nation.
