Growth of the Marine Corps
Counterintelligence (1941 - 1951)

1941 to 1951

If the disaster of Pearl Harbor accomplished anything for the United States, it demonstrated a deficiency in America's overall intelligence operations and its programs. At Pearl Harbor, our battleships were lined up in their berthing spaces in an open invitation to air attack. Our aircraft were wheeled out of their revetments and placed side-by-side on the flight line at Hickham Airfield. One of the main reasons for this was that our military leadership had underestimated Japan's strength. American Military leaders had not only underestimated Japanese capabilities, but had failed to piece together and identify simple indicators and warnings which may have averted the Japanese air strikes against Hawaii.

Many observers in Europe had predicted that Russia could not last more than six weeks against a German assault. Consequently, full attention of Allied intelligence was directed to that region of the world, completely ignoring the Japanese threat.

Prior to 1948, a formal occupational field for Marine Corps Counterintelligence did not exist. Of course this is not to say that several Marines had not participated in the field. Those who did participate in this environment had served with the "Office of Strategic Services (OSS)," during World War II. On 23 April 1943, Headquarters, Marine Corps issued a 29 page manual that outlined the mission and general instructions for Marine Corps Counterintelligence.

The first Marine Corps formal counterintelligence training took place in April 1948, when quotas were obtained for four officers and eight enlisted Marines were to attend CI training at the U.S. Army Counterintelligence Corps Center, Camp Holibird, Maryland. These Marines became the nucleus for other Marines entering Marine Corps Counterintelligence. The Marine Corps Military Occupational Skill (MOS) designation for members originally assigned to the counterintelligence field was (636) until it was change in the spring of 1950; 0210 for officers and 0211 for enlisted.

Even though Marine Corps Counterintelligence was formally instituted in 1943 to cooperate with and to assist the Naval Intelligence Service in its assigned task, formal training did not begin until the spring of 1948. However, a manual for Marine Corps Counterintelligence was published on 23 April 1943, providing a working basis and standardized procedures for Marines assigned to assist the Navy in carrying out its counterintelligence operations. Compared to today's Marine Corps Order pertaining to CI, the 1943 manual was general in scope and purpose.

In the spring of 1948, formal counterintelligence training for the Marine Corps began. Prior to 1948, counterintelligence support to the Marine Corps was provided by either the U. S. Army or the U. S. Navy. Four officers and eight enlisted Marines received orders to attend the Basic Agents Course at the U. S. Army Counterintelligence Corps Center, Camp Holibird, Maryland.

Camp Holibird, had long been the training site for Army Intelligence. Camp Holibird, located in on the eastern outskirts of Baltimore, Maryland, was later changed to Fort Holibird in the late 50s. Many individuals who received training at Camp Holibird refer to it as the "Bird." "The Bird" was also headquarters of the Army Intelligence Command during the frostier days of the Cold War.

Originally, an Army locomotive repair depot, Camp Holibird had been the training ground for a generations of Counterintelligence Corps (CIC) and Field Operations Intelligence (FOI) operatives. In the 1950s, many FOI were Eastern Europeans of fierce anti-Communist bent who spoke scant English and who were allowed off the camp only under controlled circumstances. This was mainly due to the fact that when the operatives were let off the camp grounds, they would do considerable damage to many of the saloons just outside the camp's main gate. Camp Holibird also housed the Central Records Facility, the main repository for every intelligence report ever received by the United States Army. Just after the conclusion of the Vietnam War, most of the activities formerly pursued at the "Bird" were relocated at Fort Huahuacha, Arizona; now headquarters U.S. Army intelligence. Today, "The Bird" is an industrial park that has been developed by the city of Baltimore.

The first class of Marines to be formally trained in the Counterintelligence field began on Monday, 19 April 1948 and concluded thirteen weeks later on Friday, 16 July 1948. For many Marines in attendance, the class was better known as "Training Group 666". Classes included; Report Writing, Sound Devices, Surreptitious Entry, Investigation Techniques, Observation and Description, Fingerprinting, Interrogation, Inspection and Review, Photographing, etc. As Corporal Charles Pedersen noted, "Many long hours of study time was consumed by all the enlisted Marines in attendance. This was mainly due to the fact that many of us had not been exposed to such an intense training environment throughout the course." At the beginning of each week, a "Weekly Training Schedule" was issued to each members of the class. During the twelve week course some 472 hours of training took place. The course of instruction was broken down into six areas. They included: Administrative Subject Branch - 93 hours of instruction; Investigative Subject Branch - 155 hours of instruction; Technical Subjects Branch 38 hours of instruction; Legal Subjects Branch - 30 hours of instruction; International Survey Branch - 7 hours of instruction; and Miscellaneous - 152 hours. During the CI Course most of the training concentrated on Report Writing and Typewriting - 59 hours; CIC Detachment Problems, Investigations and Interrogations - 89 hours; Investigative Photography - 16 hours; and Investigative Legal Principles - 24 hours. After graduation, many of the enlisted Marines received additional training.

The Marine Corps Military Occupational Skill (MOS) for members assigned to the CI field received a 636 Selective Service Number (SSN) after successfully completed the CI course at Camp Holibird. Many Marines assigned the 636 SSN were unable to get promoted. One member of the first class, Corporal C.L. Pedersen, upon graduation and returning to the First Marine Division, advised Headquarters, U.S. Marine Corps of the promotion problem. Corporal Pedersen prepared two letters, one dated 18 November 1948 and the other dated 10 December 1948. Both were forward to Headquarters, U.S. Marine Corps. Some two years later, in the spring of 1950, because of this potential promotion problem identified by Corporal Pedersen, Headquarters, U.S. Marine Corps changed the 636 SSN intelligence designator to its present MOS of 0210 for officers and 0211 for enlisted. Another problem developed during this MOS change. Due to an oversight, Headquarters, Marine Corps had failed to identify a line number within a Table of Organization (T/O) for the placement of Marine CI personnel to be assigned. Therefore, a Letter of Instruction (LOI) was sent to all commanders, advising them on how to effectively utilize Marines assigned to the new MOS, and that a published Marine Corps Order was being developed at Headquarters, Marine Corps for guidance and dissemination.

In 1951, the Commandant of the Marine Corps issued a classified LOI to all commanders advising them of the type of duties that assigned CI personnel should perform. At this time, Corporal Pedersen was assigned to the 8th Marine Corps Reserve District, Marine Corps Forwarding Depot, Portsmouth, Virginia as a criminal investigator with the Guard Detachment . After the issuance of the LOI, Corporal Pedersen duties changed and centered on conducting security surveys within the command, and assisting the Office of Naval Intelligence (ONI) in investigations concerning both military and civilian personnel assigned to the Depot.

At the time, only restricted Limited Duty Officers (LDOs) and Warrant Officers (WOs) could be assigned a primary MOS of 0210 upon successful completion of the required CI training. All other officers, who were assigned to the CI field, were able to carry a secondary or additional MOS of 0210.

The second class of Marines to be trained in counterintelligence began on 27 September 1948 and concluded on 14 January 1949. Marines attending the second class were:

For many of the CI Marines who were in the first and second class at the "Bird", continued to provide assistance to the Naval Investigative Service (NIS), prior to the outbreak of hostilities during the Korean War. Tactical CI training was minimal or non-existent until the outbreak of the Korean War. During the Korean War, CI Marines were assigned to and worked with Army CI. It was not until after the Korean War that the Corps began to focus on a true Marine CI mission. The first Marine Corps Counterintelligence General Order, Number 55, issued by Headquarters, Marine Corps whch outlined the Corps CI mission for both tactical and garrison environments. The order was issued on 28 November 1949. The 1949 publication was unlike that of the first manual which had been published in 1943 in that it defined the Marine Corps CI mission. The 1943 manual, identified only how the Marine Corps was to provide support to the Naval Investigative Service (NIS), and did not depict a Marine Corps mission. After the end of the Korean War, several changes refining the Marine Corps CI mission and its methodology for carrying out that mission were published.
