History: The Communications Officer School was formally established during the height of World War II on 1 June 1944, under the leadership of Lieutenant Colonel C. Nelson. At that time, a 20-week Communications Officer Course, which provided instruction on the newest communications techniques, procedures, and equipment, was designed to help standardize communications planning and employment throughout the Marine Corps based on lessons learned acquired through nearly three years of war. The first class, which was the forerunner to the Advanced Communications Officer Course, graduated in October 1944.
In February 1954, ground was broken for a new, $300,000 building on the edge of the Potomac in Quantico. The building was dedicated on 12 December 1955 and named "Edson Hall" in honor of Major General Merritt A. Edson, the World War II Marine hero, leader of the famed "Edson's Raiders," and a vocal proponent of the criticality of communications in combat.
The first Communication Officers Orientation Course was convened in April 1955. The four-week course was designed to give recent Basic School graduates a background in communications prior to reporting to the Fleet Marine Forces. That course has evolved into the current Basic Communications Officer Course (BCOC), a 21-week course designed to provide initial communications skills training to company grade officers. The course stresses hands-on equipment training combined with realistic field exercises.
In 1973, the school's advanced course lengthened to 41 weeks and additional emphasis was placed on amphibious command and control techniques. In 1989, the course became the Command and Control Systems Course (CCSC) and addressed technological advances in C2 systems used by commanders. Expeditionary Warfare School was created in 2002, combining elements of Marine Corps career-level PME curricula (the Amphibious Warfare School and CCSC), resulting in Communications School refocusing its career-level instruction with the creation of an advanced course designed to train communications planning at the MSC level. That course is now the ten-week Advanced Communications Officer Course (ACOC), designed for captains and majors. February 2002 also saw the creation of three nine-week courses for qualification of Warrant Officers in the planning, design, engineering and employment of transmission systems, tactical switching, and data networks.
Communications School continues to provide quality instruction at both the basic and advanced levels to selected Marine Corps communications officers, as well as officers from other services and nations. Many graduates of this school have achieved success in a wide variety of endeavors, including U.S. Senator John Warner (R-Va.) and General Alfred M. Gray (ret), 29th Commandant of the Marine Corps.
During 2014 Communication School was relocated to Twentynine Palms California under Marine Corps Communication Electronics School.
On 12 Mar 2015 Communication Training Battalion was formally activated in compliance with MCBul 5400 dtd 18Dec14.
