Who We Are
It is the mission of United States Army Counterintelligence (ACI) to detect, identify, counter, neutralize, and exploit Foreign Intelligence Services and International Terrorist Organizations targeting U.S. Army personnel and equities.
ACI is one of only three DoD Counterintelligence (CI) entities designated by the Office of the Under Secretary of Defense for Intelligence and Security, as a "Military Department CI Organization" or "MDCO." The other two DoD MDCO's are the United States Air Force Office of Special Investigations (AFOSI) and the Naval Criminal Investigative Service (NCIS). As an MDCO, Special Agents of ACI are recognized federal law enforcement officers tasked with conducting criminal CI investigations in conjunction with other CI activities.
ACI in Europe is aligned to support U.S. Army Europe and Africa; U.S. European Command; U.S. Africa Command; V Corps; 7th Army Training Command; 10th Army Air & Missile Defense Command; 19th Battlefield Coordination Detachment; 21st Theater Sustainment Command; and Southern European Task Force – Africa.
Area of Responsibility
Based in Belgium, the Benelux Field Office provides coverage to Belgium, Luxembourg, The Netherlands, United Kingdom, and Northern France.

Special Agent Careers
Being an ACI Special Agent is one of the most challenging and fulfilling careers in the military or federal government. ACI Special Agents gain broad experience and are given responsibility early on in their careers. To succeed, ACI Special Agents must have high moral standards, integrity, the courage to do what is right and respect for, and knowledge of the law.
As a condition of employment, all ACI Special Agents are required to sign a mobility agreement. This may result in one or more overseas moves and periodic assignments within the Continental United States (CONUS) and throughout an agent's career with ACI. In addition, ACI Special Agents may be required to deploy on assignments to support military forces in high-risk environments.
