0204 - Counterintelligence/Human Source Intelligence (CI/HUMINT) Officer                2ndLt - 1stLt

CI/HUMINT Officers serve in both counterintelligence and human intelligence billets. They command and/or lead CI/HUMINT units in
tactical information gathering operations and activities in support of identified collection requirements. CI/HUMINT Officers command, plan, and direct the employment and execution of CI/HUMINT units and approved operations and activities. CI/HUMINT Officers advise commanders and staffs on information collection efforts and CI/HUMINT operations and activities. Through the Intelligence Officer, they support the overall intelligence effort the command.


CI/HUMINT Officers work to collect information from the local population and personnel within the area of operations to develop an on-the-ground understanding of everything that may effect Marines in the performance of their duties.  This includes meeting with local leaders, interrogating detainees, developing relationships with locals to gather information, and discovering what means other organizations may be using to collect information on the Marine Corps' operations in the AO.  Based on this information collected, CI/HUMINT Officers will provide reports on changing AO conditions to commanders and advise them on ways to proceed in operational planning and execution.  Additionally, CI/HUMINT Officers spearhead efforts to deny intelligence gathering opportunities to enemies and lead Marine Corps counterintelligence operations.

A typical first tour assignment for a CI/HUMINT Officer is platoon command in an Intelligence Battalion or to work in a principal staff office at either a  regiments or headquarters element within the MARDIV or the MLG as part of the GCE or LCE of the MAGTF, respectively. 

CI/HUMINT officers are highly specialized and in a low-density MOS.  They coordinate the efforts of 0210 CI/HUMINT Operations Officers and 0211 CI/HUMINT Specialists assigned to CI/HUMINT Platoons.  Much of what these units, and the rest of the intelligence occupation field, do are not publicly released.  For one sea-story of CI/HUMINT at work during the invasion of Iraq, click here.

CI/HUMINT Officers task CI/HUMINT collection elements, manage operational funds and debriefs, conduct dissemination and CI Inquries, conduct sensor cross-cueing, analyze source information, and perform intelligence preparation of the battlespace (IPB).

There are roughly 50 CI/HUMINT Officers in the Marine Corps.  To become an 0204, Officers must complete the MAGTF Counter Intelligence/Human Intelligence Course, Marine Corps Intelligence Schools, Marine Corps Detachment Dam Neck, Virginia. Officers must have a current single scope background investigation/T5 investigation, and submit to a counterintelligence scope polygraph examination.  Intelligence MOS Marines are required to have a Defense Language Aptitude Battery (DLAB) test score on file in their official military personnel file (OMPF). Intelligence MOS Marines that score above 100 on the DLAB may be designated to attend formal language training. There is no minimum DLAB score required. Intelligence officers will be administered the DLAB before being assigned the 0204 primary MOS.
