Army Counterintelligence.png


It is the mission of U.S. Army Counterintelligence (ACI) to detect, identify, counter, neutralize, and exploit hostile Foreign Intelligence Entities (FIE) and International Terrorist Organizations (ITO) targeting U.S. Army personnel and equities, as well as, additional joint equities as designated by the Department of Defense (DoD).

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 U.S. 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 Europe is aligned to support U.S. Army Europe and Africa (USAREUR-AF), U.S. European Command (EUCOM), and U.S. Africa Command (AFRICOM).


Based in Germany, the Wiesbaden Field Office provides coverage for all of Germany East of the Rhine (except the states of Bavaria and Baden-Wuerttemberg), Denmark, Norway, Sweden and Finland.

  • Unauthorized personnel (U.S. or foreign) ask about Army or DoD force capabilities, critical information, or technologies
  • Suspecting someone having unauthorized contact with foreign government, military, or intelligence personnel
  • Suspecting potential compromise of defense information or security violations
  • Suspecting unauthorized intrusions or theft of sensitive computer system data
  • Suspecting someone is associated with or aiding a terrorist organization
  • Observing indicators of potential terrorist-associated insider threats
  • Any other matters you are unsure about and feel may be of interest to ACI


TARP is a Department of the Army (DA) program covered under Army Regulation 381-12, mandating that all DA personnel report certain matters of CI interest to ACI. In addition, DA personnel (whether military or civilian) must receive a TARP briefing annually. The preferred method for conducting TARP briefing training is in-person, and required to be given by a qualified ACI Special Agent.


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, courage to do what is right, and respect/knowledge of the law.

If you are looking to join ACI as a military agent and are not yet enlisted, contact a U.S. Army recruiter today to ask about how to become an ACI Special Agent. If you are already in the military, view the prerequisites at (requires CAC):
