Counterintelligence/Human Intelligence (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 and advise commanders and staffs on information collection efforts and CI/HUMINT operations and activities. Through the Intelligence Officer, they support the overall intelligence effort of the command.

Are there any prerequisites to becoming a Counterintelligence/Human Source

Intelligence Officer

(1) Must meet SCI eligibility guidelines based on a SSBI/T5 Investigation.

(2) Intelligence MOS Marines are required to have a DLAB test score on file in their 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 before being assigned the 0204 PMOS. (3) Must be willing to submit to a Counterintelligence Scope Polygraph Exam.

Where do I go after TBS?

After TBS, officers must complete the 45 day Tactical Intelligence Officer Course (TIOC) at MCIS aboard the NAS Oceana Dam Neck Annex, VA. TIOC is a prerequisite for the 0203, 0204, 0206, and 0207 MOSs and is designed to train Marine Officers in the combat, operational, and administrative skills required of an Intelligence Officer in the Operating Forces. The learning objectives are achieved through reading doctrinal publications, policy, and emerging concepts followed by guided discussion, informal lectures, or group practical application instructional methodologies.

Following TIOC, officers must complete the 139 day MAGTF CI/HUMINT Course at MCIS aboard the NAS Oceana Dam Neck Annex, VA. The purpose of the course is to train, certify, and credential Marines in the 0203 MOS by providing training in the techniques and methods applicable to CI/HUMINT operations and activities in support of MAGTF operations globally and in a joint environment. The course provides instruction on: debriefing and intelligence fundamentals; interrogations; counterintelligence agent; military source operations, and counterintelligence collections.

What is it like being a Counterintelligence/Human Source Intelligence


A typical first tour assignment for a CI/HUMINT Officer is within an Intelligence Battalion as part of the CE of the MAGTF. There is one Intelligence Battalion subordinate to each MEF Information Group (MIG): 1st Intelligence Battalion aboard MCB Camp Pendleton, CA (I MIG); 2nd Intelligence Battalion aboard MCB Camp Lejeune, NC (II MIG); and 3rd Intelligence Battalion aboard Camp Hansen, MCB Camp Smedley D. Butler, Okinawa, Japan (III MIG). CI/HUMINT Officers in their first tour typically serve as a Platoon Commander or CI/HUMINT Detachment (CHD) Commander. CI/HUMINT Officers may also serve as the CI/HUMINT Company Executive Officer. CI/HUMINT Officers in their first tour are typically responsible for managing, training, and employing the 15-30 CI/HUMINT Specialists under their charge and are organized as CI/HUMINT Detachments (CHDs) to support MAGTF operations. This support encompasses the full range of tactical CI and HUMINT operations, including screening operations, interrogation/debriefing of enemy prisoners of war and persons of intelligence interest, conduct of CI force protection source operations, conduct of CI surveys and investigations, preparation of CI estimates and plans, translation of documents, and limited exploitation of captured material.
