Force Reconnaissance (FORECON) are United States Marine Corps deep reconnaissance companies that supply military intelligence to the command element of the Marine Air-Ground Task Force (MAGTF). Force Reconnaissance companies, unlike USMC division reconnaissance, report to the Marine expeditionary force (MEF) and provide direct action and deep reconnaissance during large-scale operations.
1st Reconnaissance Battalion is a reconnaissance battalion in the United States Marine Corps. It is a stand-alone battalion with no parent regiment. Instead, it falls directly under the command of the 1st Marine Division. 1st Recon Bn is located at Marine Corps Base Camp Pendleton in San Diego, California.
The 2nd Reconnaissance Battalion is a reconnaissance battalion in the United States Marine Corps. Located at Marine Corps Base Camp Lejeune, North Carolina, the battalion falls under the command of the 2nd Marine Division and the II Marine Expeditionary Force.
The United States Marine Corps is organized within the Department of the Navy, which is led by the Secretary of the Navy (SECNAV). The most senior Marine commissioned officer is the Commandant of the Marine Corps, responsible for organizing, recruiting, training, and equipping the Marine Corps so that it is ready for operation under the command of the unified combatant commanders. The Marine Corps is organized into four principal subdivisions: Headquarters Marine Corps, the Operating Forces, the Supporting Establishment, and the Marine Forces Reserve.
The United States Marine Corps's Amphibious Reconnaissance Battalion, formerly Company, was a Marine Corps special operations forces of United States Marine and Hospital corpsman that performed clandestine operation preliminary pre–D-Day amphibious reconnaissance of planned beachheads and their littoral area within uncharted enemy territory for the joint-Navy/Marine force commanders of the Pacific Fleet during World War II. Often accompanied by Navy Underwater Demolition Teams and the early division recon companies, these amphibious recon platoons performed more reconnaissance missions than any other single recon unit during the Pacific campaigns.
The Observer Group was a joint-United States Army/Marine Corps unit that was the first in the United States and Fleet Marine Force to be organized and trained specifically for amphibious reconnaissance. The Observer Group experimented in the methodology and equipment for projecting reconnaissance from the sea before the establishment of the OSS Maritime Unit, the Underwater Demolition Teams, and before the Army Special Forces and Air Commandos. It was also the birth of naval amphibious intelligence.
The Marine Corps Test Unit 1, or MCTU #1, was an experimental testing unit of the United States Marine Corps. It was established outside the Fleet Marine Force for the development of specialized tactics, techniques and organizational concepts, and to evaluate its tangible employment in the nuclear age. It reported directly to the Commandant of the Marine Corps.
A Special Amphibious Reconnaissance Corpsman (SARC) is a United States Navy hospital corpsman who provides MARSOC and other USSOCOM units advanced trauma management associated with combatant diving and parachute entry. Traditionally, they are attached to the Marine Corps Force Reconnaissance companies to help support the Command Element of the Marine Air-Ground Task Force in special reconnaissance missions.
A Maritime Special Purpose Force (MSPF) is a United States Marine Corps specialized sub-unit of a Marine expeditionary unit. A MSPF is deployed to give the commanders low profile, two-platoon surgical emplacement in the accessible littoral regions. The MSPF provides the enhanced operational capability and precision skills to complement, enable, and execute selected conventional, maritime special operations. They can also perform operations not resident in traditional amphibious raid companies.
The United States Marine Corps is tasked by Department of Defense directive to "conduct complex expeditionary operations in the urban littorals and other challenging environments" and "conduct amphibious operations, including engagement, crisis response, and power projection operations to assure access." Before 2006, the Marine Corps was the only branch of the Armed Forces that did not have any of its special warfare elements participating in the United States Special Operations Command (USSOCOM), due to confining its special operations capabilities only for the purpose to the Fleet Marine Force.
The reconnaissance mission within the United States Marine Corps is divided into two distinct but complementary aspects; Marine Division Recon and Force Reconnaissance.
The United States Marine Corps Scout and Sniper companies and the Scouts (Tank) companies of the tank battalions were the first among the division's reconnaissance assets. They existed around the same exact moment when 1st and 2nd Marine Division were created. In 1941, each regiment had a scout and sniper platoon. They were assigned to the regimental Headquarters and Service Company. These companies were used in variety of tasks and, on occasion in severe combat, were used as "spare" rifle companies. When 6th Marine Division deactivated after the end of World War II, its recon assets also deactivated. Only the current Marine Division Recon Battalions that exist today hold history reference to the Scout and Sniper Companies.
The United States Marine Corps Reconnaissance Training Company trains Marines in the amphibious environment as a Reconnaissance Marine, MOS 0321. It is under the Advanced Infantry Training Battalion (AITB) of the School of Infantry (West), Marine Corps Base Camp Pendleton, California.
1st Force Reconnaissance Company conducted deep reconnaissance and direct action raids in support of I Marine Expeditionary Force requirements across the range of military operations to include crisis response, expeditionary operations and major combat operations. 1st Force Recon Company was deactivated on 26 October 2006 and the majority of the personnel were used to establish the 1st Marine Special Operations Battalion.
The Second Force Reconnaissance Company was the deep reconnaissance/direct action that was assigned to the Fleet Marine Force, Atlantic and its subordinate elements of the Marine Air-Ground Task Force.
The two amphibious/ground reconnaissance assets of the United States Marine Corps, Division and Force Reconnaissance, are generally trained in the same aspect and environment of intelligence collection for a Marine Air Ground Task Force (MAGTF) Commander, regardless of their difference in tactical area of responsibility (TAOR). However, in light of their distinctive responsibilities in their assigned areas of operations—whereas Division Recon conducts close and distant operations, Force Recon conducts deep operations—these two separate reconnaissance assets manage their own training protocols to fit their mission-oriented objectives.
The United States armed forces classify reconnaissance missions as "close" or "short-range"; "distant" or "medium-range"; and "deep" or "long-range".
Ground Intelligence Officer is a primary military occupation code of a U.S. Marine Corps intelligence officer. Ground intelligence officers serve as staff officers and commanders in the operating forces and are responsible for analyzing intelligence and planning, deployment and tactical employment of ground surveillance and reconnaissance units. The Ground Intelligence Officer can be a Recon Marine after their training is done.
The Reconnaissance Battalion or RECON is an elite recon battalion in the Royal Thai Marine Corps (RTMC), falling under the Royal Thai Marine Division. A special operations forces unit, it is capable of conducting land, maritime, and air operations.
