This is a list of current United States Marine Corps battalions, sorted by the mission they perform.
See also: Ground combat element
The ground combat element (GCE) consists of those combat and combat support units whose primary mission is to, (1) engage with and destroy the enemy by fire and/or maneuver, and/or shock effect, performed by infantry, field artillery, and tank units, (2) provide close battlefield support to other GCE units by assault amphibian, combat assault, light armored reconnaissance, reconnaissance, and combat engineer units, or (3) provide immediate command and control, and limited logistical support including consolidated Navy personnel administration and motor transport (medium truck) support to subordinate GCE battalions and regiments (infantry and artillery only) by Marine division (MARDIV) headquarters battalions. Additionally, this battalion provides communications networking and law enforcement support across the GCE. The headquarters battalion also includes the division band, whose tactical mission is to serve as a provisional rifle platoon in providing division headquarters security.
Note: Some GCE battalions and regiments are provided air liaison officers/forward air controllers (i.e., Marine Corps naval aviators — aircraft pilots, and naval flight officers — airborne weapons and sensor systems officers) with specialized skills in coordinating air support of ground units) from the Marine Aircraft Wing (MAW) of the aviation combat element (ACE). These officers facilitate employment of Marine aviation in support of GCE units to perform offensive air support (e.g., close air support), assault support (e.g., troop, cargo, and casualty transport, aerial command and control, liaison, communications, and illumination, and close-in fire support by light/attack helicopters), and aerial reconnaissance (e.g., tactical reconnaissance and artillery spotting).
Infantry battalions are the heart and soul of the ground combat element. The mission of locating, closing with, and destroying the enemy with fire and maneuver and repelling the enemy's assault with fire and close combat lies with the "grunts". Marine infantry battalions often have limited organic equipment outside of small arms, infantry crew-served weapons (e.g., heavy machine guns, medium mortars, and anti-tank missiles), and a few light tactical trucks. Marine infantry primarily maneuvers by foot as light infantry, and must be supplemented with additional trucks to become motorized infantry or Amphibious Assault Vehicles to become mechanized infantry.
A Marine infantry battalion is usually organized into three rifle companies, a weapons company, and a headquarters and service company. The rifle company has a company headquarters, three rifle platoons, with three rifle squads each, and a weapons platoon with medium machineguns, mortars, and assault weapons sections. The weapons company includes a company headquarters, a heavy machinegun platoon, an 81mm mortar platoon, and an antiarmor platoon. Sometimes, the commander will mix these into Combined Anti-Armor Teams. The headquarters and service company includes all command, administration, intelligence, operations, logistics, and communication Marines and equipment, as well as the battalion's Scout Sniper platoon and Battalion Aid Station (BAS) staffed by U.S. Navy Hospital Corpsman. By 2030 three battalions will be disbanded, and some reflagged: 1/8th becoming 2/2nd, 2/8th becoming 4/6th, 8th Marine HQ and 3rd Btn disband.

Field artillery units provide indirect, long-range cannon and rocket fire support for the Marine Air-Ground Task Force. Currently, artillery regiments contain two or three (11th Marines only) cannon battalions and are equipped with the M777 lightweight, towed, 155 mm, medium howitzer and the Expeditionary Fire Support System (EFSS) 120 mm, heavy mortar. Two regiments (11th Marines and 14th Marines) also have one rocket battalion equipped with the M142 High Mobility Artillery Rocket System (HIMARS) equipped with the MGM-140 ATACMS surface-to-surface, guided missile. Marine artillery battalions contain a Headquarters Battery and three or four firing batteries. Firing batteries contain a headquarters platoon (including a liaison section with three forward observer teams) and one or two firing platoons (depending upon weapons systems). The firing platoon(s) contain a battery operations center, a fire direction center, and four or six artillery sections (depending upon weapon system). Counter-battery radar is usually a regimental asset, but can be detached to augment battalions or batteries. By 2030 all but five artillery batteries will be disbanded.

The mission of an armor unit is to conduct and support amphibious operations and other operations as required by landing and transporting to inland objectives the surface assault elements and their equipment, and by conducting light armored reconnaissance and limited offensive and defensive operations. When task-organized with infantry, tanks, and other forces, the battalion conducts combined arms operations as a separate maneuver element in support of the Marine Division.
Currently, Assault Amphibian (AA) battalions utilize the Amphibious Assault Vehicle (AAVP-7A1) and consist of a headquarters and service company and two to six AA companies. Each AA company is equipped with 42 AAVs (including personnel, command, and recovery variants) organized into three platoons of 12 AAVs each and an additional six AAVs in the company headquarters. Each AA platoon is capable of transporting an entire Marine rifle company plus any dismounted attachments (e.g., mortar forward observer teams, anti-tank missile crews, scout/sniper or reconnaissance squads) thus transforming into amphibious/mechanized infantry. (One AA company is capable of transporting the assault echelon of a Marine infantry battalion.) Although plans were in place to replace it with the Expeditionary Fighting Vehicle, the cancellation of the program is going to prolong use of the AAV.
Light Armored Reconnaissance (LAR) battalions use the LAV 25 series of vehicles and consist of a headquarters and service company and four LAR companies. Each LAR company is equipped with 25 LAVs (including 14 LAV-25, two mortar, four anti-tank, one command & control, three logistics, and one recovery variant).

The mission of combat engineers is to provide mobility, counter mobility, survivability, and limited general engineering support. Mobility includes the assessment and fortification of roadways and bridges, the clearing of enemy obstacles and landmines, and assault breaching. Counter mobility includes creating obstacles and barriers for the enemy, which could include the destruction of structures and/or bridges. Survivability includes the fortification of positions and the construction of new outposts. Other jobs can include Explosive Ordnance Disposal (EOD), construction, and utilities (such as generators and refrigeration). Currently, combat engineers use a variety of tools for their trade. Some vehicles include the M9 Armored Combat Earthmover, D7 Bulldozer, M60A1 Armored Vehicle Launched Bridge, and various cranes and forklifts. Each combat engineer battalion consists of a headquarters and service company, three combat engineer companies, one mobility assault company, and an engineer support company.

The mission of the reconnaissance battalions is to obtain information by visual observation about the activities and resources of an enemy or potential enemy, or about the meteorologic, hydrographic, or geographic characteristics of a particular area. They specialize in amphibious recon, including hydrography; as well as airborne recon, infiltration via surface, subsurface and airborne operations, and conducting limited scale raids and ambushes. The battalions consist of a headquarters and service company and one to four reconnaissance companies (divisional assets, individual companies usually attached to an RCT). All battalions (except 4th Recon) also have a force reconnaissance company dedicated to provide deep reconnaissance and direct action capability to a MEF HQ. (Two additional separate force reconnaissance companies exist in the Marine Forces Reserve.)

See also: Logistics Combat Element
The logistics combat element (LCE) consists of those combat service support units whose primary mission is to, (1) provide direct combat logistics (i.e., motor transport and landing support, and limited engineer support, equipment maintenance, and ground supply services) to specified GCE units or certain aviation combat element (ACE) units as provided by combat logistics battalions and separate combat logistics companies, (2) provide general combat service support across the Marine Air Ground Task Force (MAGTF) by specialized service support battalions, including: dental, engineer support, maintenance, medical, supply and transportation support battalions, or (3) provide immediate command and control, and consolidated Navy personnel administration to subordinate LCE battalions and regiments by the Marine Logistics Group (MLG) headquarters and service battalion. Additionally, this battalion provides communications networking and law enforcement support across the LCE. The headquarters and service battalion also provides specialized services, including: military postal service, Marine Corps Exchange (MCX), and other personal services, to units of all four MAGTF elements (i.e., GCE, ACE, LCE, and CE).
Combat logistics battalions (CLB) provide combat service support for the GCE and ACE beyond their organic capabilities. The battalions primarily provide motor transport and logistics control and materiel handling (i.e., landing support) services, and limited engineer, maintenance, and supply services, to dedicated Regimental Combat Teams (RCT) or Marine Expeditionary Units (MEU). CLBs that support RCTs typically consist of a headquarters and service company, and three support companies (engineer, maintenance, and transportation); those CLBs that support MEUs typically consist of several functional units (individual units may be styled as either a section, platoon, detachment, or company depending upon the size of unit, function, and the unit's parent battalion/regiment/group). In addition to a headquarters and service unit, these CLBs contain units dedicated to providing: air delivery, communications, engineer, explosive ordnance disposal, health services (medical and dental), landing support, law enforcement (military police), maintenance, motor transport, and supply support to the MEU.

The command element (CE) consists of those command and control, communications, intelligence, law enforcement, electronic warfare/signals intelligence/electronic intelligence, civil affairs, air/naval gunfire liaison, and force reconnaissance units that enable the MAGTF commander to effectively fight the GCE and ACE, with support from the LCE, to defeat the enemy and/or accomplish other assigned missions.
Note: U.S. Marine Corps organizational doctrine places communications, intelligence, and law enforcement battalions and their organic companies/detachments in the MAGTF headquarters group or CE. However, intelligence (i.e., ground intelligence) may also be considered as a GCE function (primarily located in the infantry battalion scout/sniper platoon) and communications and law enforcement may also be considered as logistics functions. Most GCE battalions and regiments, and ACE squadrons/battalions (LAAD), Marine aircraft groups (MAGs), and Marine air control groups (MACGs), contain some organic communications assets such as battalion and regimental communications platoons, MARDIV and MLG communications companies, and Marine wing communications squadrons. In addition, MARDIVs, Marine Aircraft Wings (MAWs), and MLGs also possess a limited organic law enforcement capability.
Communications battalions provide communication support for the MAGTF as part of the MEF headquarters groups. They also perform networking and data services when deployed. The battalions typically consist of a headquarters and service company, three communications companies, and a support (maintenance) company.

The LE battalions will be a force multiplier to the operating forces forward deployed by assisting in an array of missions from law enforcement, route regulation, humanitarian assistance, nonlethal weapons training, and military working dog employment. Marine Corps Bulletin 5400, released in September 2011, called for the reactivation of the 1st, 2nd, 3rd, and 4th Military Police Battalions, now designated as law enforcement battalions, in each Marine Expeditionary Force and Marine Forces Reserve. Three law enforcement battalions were activated in June 2012, with each battalion consisting of a headquarters and service company and two or more law enforcement companies. Each included "500 military police officers [sic] and dozens of dogs." (Note: As military units, each battalion contains only about 30 to 40 "officers," as the majority of the military police Marines are enlisted members and not officers. "Officers" as in any military organization, command the battalion and its organic companies and platoons and serve as staff officers in the battalion headquarters.) By 2030 all of the battalions will be disbanded following the re-organisation announcement.

While these units are designated as companies, they are commanded by a Lt. Col. who is assisted by an executive officer and an executive staff (S-1, S-2, etc.). The company's organic platoons often operate independently and are normally commanded by a major (ANGLICO) or captain (FORECON).
Air Naval Gunfire Liaison companies (ANGLICO) provide Marine Air-Ground Task Force (MAGTF) commanders a liaison capability, with foreign area expertise, to plan, coordinate, and conduct terminal control of fires in support of joint, allied, and coalition forces. ANGLICO units are separate companies (i.e., not organic to a battalion or regiment) reporting directly to one of the three MEF HQ Groups (1st, 2nd, & 5th ANGLICO) or the Forces HQ Group, Marine Forces Reserve (3rd, 4th, and 6th ANGLICO).
Fleet Marine Force Reconnaissance (FORECON) companies provide Marine Air-Ground Task Force (MAGTF) commanders with deep reconnaissance and direct action capability. The FORECON companies of the three MEFs are organic to their respective divisional reconnaissance battalions and are under operational control of their parent MEF HQ Group. The 3rd and 4th FORECON companies are separate companies reporting directly to the Forces HQ Group, Marine Forces Reserve and are dedicated to supporting II MEF and I MEF, respectively, whenever a MEF's active duty FORECON company is not available.

With the exception of the Low Altitude Air Defense battalions, which are organic to the Marine Air Control Group (MACG) of a Marine Aircraft Wing (MAW), and are a component of the Aviation Combat Element (ACE) of a Marine Air Ground Task Force (MAGTF), the battalions in this section perform missions either within the Operating Forces of the Marine Corps but outside the MAGTF structure, or within the Supporting Establishment.
The Marine Raider battalions of the Marine Raider regiment provide the principal special operations combat capability of the Marine Corps Forces Special Operations Command in performing direct action, special reconnaissance, counter-terrorism, information operations, foreign internal defense, and unconventional warfare missions. The battalions consist of a headquarters and service company and four special operations companies.
