The United States Armed Forces are the military forces of the United States. The armed forces consist of six service branches: the Army, Marine Corps, Navy, Air Force, Space Force, and Coast Guard. All six armed services are among the eight uniformed services of the United States.
A Marine expeditionary unit is the smallest air-ground task force (MAGTF) in the United States Fleet Marine Force. Each MEU is an expeditionary rapid reaction force ready to answer any crisis, whether it be disaster aid or a combat mission. Marine amphibious unit (MAU) was the name used until the late 1980s.
Insignias and badges of the United States Navy are military badges issued by the United States Department of the Navy to naval service members who achieve certain qualifications and accomplishments while serving on both active and reserve duty in the United States Navy. Most naval aviation insignia are also permitted for wear on uniforms of the United States Marine Corps.
United States Navy Explosive Ordnance Disposal technicians render safe all types of ordnance, including improvised, chemical, biological, and nuclear. They perform land and underwater location, identification, render-safe, and recovery of foreign and domestic ordnance. They conduct demolition of hazardous munitions, pyrotechnics, and retrograde explosives using detonation and burning techniques. They forward deploy and fully integrate with the various Combatant Commanders, Special Operations Forces (SOF), and various warfare units within the Navy, Marine Corps, Air Force and Army. They are also called upon to support military and civilian law enforcement agencies, as well as the Secret Service.
U.S. Coast Guard Port Security Units are Deployable Specialized Forces organized for sustained expeditionary security and anti-terrorism. They provide Anti-Terrorism Force Protection (ATFP) missions, which include harbor and port defense, protection of High Value Assets (HVAs), expeditionary security, Sea Lines of Communications (SLOCs), special missions. and coastal surveillance. PSUs are expeditionary units that conduct OCONUS missions in support of a requesting regional combatant commander. PSUs usually operate under the direction of the Coast Guard's Pacific Area (PACAREA) command but are unique in that they are the only Coast Guard units that can be quickly requested by the Department of Defense.
The EXW qualification is a warfare qualification awarded to enlisted United States Navy personnel assigned to U.S. Navy expeditionary combat units, who satisfactorily complete the required qualification course and pass a qualification board hearing. The program was approved July 31, 2006 by then-Chief of Naval Operations Adm. Michael Mullen.
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 structure of the United States Navy consists of four main bodies: the Office of the Secretary of the Navy, the Office of the Chief of Naval Operations, the operating forces, and the Shore Establishment.
Expeditionary Strike Group 3 is an expeditionary strike group (ESG) of the U.S. Navy. Expeditionary strike groups combine the capabilities of surface action groups, submarines, and maritime patrol aircraft with those of Amphibious Ready Groups for deployment and maintaining staff proficiencies to provide fleet commanders with a highly flexible, ready fly-away unit. It is capable of projecting expeditionary striking power in the maritime, littoral, and inland environs in support of U.S. national interests.
In the United States Navy, the expeditionary strike group (ESG) is a coordinated group of surface ships, aircraft, submarines, and other naval assets. In contrast to carrier strike groups (CSGs), which emphasize air power and are led by a supercarrier, ESGs are strongly suited for amphibious warfare and are led by an amphibious assault ship. The ESG concept was introduced in the early 1990s, based on the Naval Expeditionary Task Force. The U.S. Navy fields nine expeditionary strike groups.
The Special Warfare Combat Crewmen (SWCC ) are United States Naval Special Warfare Command personnel who operate and maintain small craft for special operations missions, particularly those of U.S. Navy SEALs. Their rating is Special Warfare Boat Operator (SB).
The Naval Coastal Warfare Community is a component of the United States Navy, part of Naval Expeditionary Combat Command. The Maritime Expeditionary Security Force (MESF), formerly known as the Mobile Security Forces (MSF), has the primary mission of force protection conducted through fleet support with operations around the world. Anti-Terrorism and Force Protection missions include harbor and homeland defense, coastal surveillance, and special missions.
The Maritime Expeditionary Security Force (MESF) is a force within the United States Navy under the organizational structure of the Navy Expeditionary Combat Command. The MESF originated from the Naval Coastal Warfare community which transitioned to the MESF in the early 2000s. The MESF's primary mission is force protection with deployed operations occurring around the world. Anti-terrorism and force protection missions include harbor and maritime infrastructure defense, coastal surveillance, and special missions. Specialized units work together with MESF squadron staffs providing intelligence and communications. MESF units deploy worldwide to detect, deter, and defend an area or unit. Recent locations include the United States, Panama, Korea, Saudi Arabia, Kuwait, Iraq, Afghanistan, Bahrain, United Arab Emirates, and Egypt.
The Riverine Squadrons of the United States Navy are elements of the Navy Expeditionary Combat Command (NECC). According to the Navy: “The Navy’s Riverine force focuses on conducting Maritime Security Operations and Theater Security Cooperation in a riverine area of operations or other suitable area. The force is capable of combating enemy riverine forces by direct fire, or by coordinating supporting fire. It will share battle space with the other Services in an effort to close the seams in Doctrine, Tactics, Techniques, and Procedures, and Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance.”
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.
Marine expeditionary unit (special operations capable) (MEU(SOC)) is a program created by the United States Marine Corps (USMC) and the United States Navy (USN) in 1985 for Marine expeditionary units (MEU). The program enhances MEUs providing them with additional training and equipment to become certified as special operations capable with a Maritime Special Purpose Force (MSPF). The designation special operations capable is unique to the Marine Corps and means in relation to special operations. The role of a MEU(SOC) however is not equivalent to the special operations role of special operations forces. Although considered special operations capable a MEU(SOC) does not form part of the United States Special Operations Command (USSOCOM) established in 1987 or the United States Marine Forces Special Operations Command (MARSOC) later established in 2006.
The Deployable Specialized Forces (DSF) —formerly Deployable Operations Group— are part of the United States Coast Guard that provide highly equipped, trained and organized deployable specialized forces, to the Coast Guard, United States Department of Homeland Security (DHS), United States Department of Defense (DoD) and inter-agency operational and tactical commanders. The command was formerly headquartered in Arlington, Virginia where it was established on 20 July 2007, and was commanded by a captain. It was decommissioned by the Commandant of the Coast Guard, Admiral Robert Papp on 1 October 2013, with units previously assigned to the DOG being split between Coast Guard Pacific and Atlantic Area commands. The units were subsequently reorganized under Deployable Specialized Forces (DSF).
The Tactical Divers Group is the premier special operations force of the Argentine Navy. The Buzos Tácticos are based at Base Naval Mar del Plata (BNMP) on the Atlantic coast of Argentina. Its men are highly qualified combat divers, EOD/demolition technicians, and paratroopers.
The Coastal Riverine Force (CORIVFOR) is a unit of the United States Navy within the organizational structure of the Navy Expeditionary Combat Command (NECC). The unit was established following the merger of Riverine Group 1 and the Maritime Expeditionary Security Group 1 & 2 on June 1, 2012. Its express purpose is to provide port and harbor security, and offshore protection for maritime infrastructure and Military Sealift Command ships operating in coastal waterways.
