The mission of a tank battalion is to conduct operations ashore utilizing maneuver, armor protected firepower and shock action in order to close with and destroy the enemy, as well as provide expertise in anti-tank operations. Currently, tank battalions utilize the M1A1 Abramsmain battle tank and the M88A2Recovery Vehicle.
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 battalions utilize the Amphibious Assault Vehicle (AAVP-7A1), though plans are to replace it with the Expeditionary Fighting Vehicle. Light Armored Reconnaissance battalions use the LAV 25 series of vehicles. The Combat Assault Battalion is unique in that it combines both vehicles into a single battalion.
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 breachingdisambiguation needed. 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.
Headquarters battalions serve as the command and control nexus for a Marine division or logistics group. They contain the administration, intelligence, operations, planning, logistics, communication, and public affairs control of the division.
Combat logistics battalions provide logistics capabilities for the GCE and ACE beyone their own organic capabilities. Each battalion is self-sufficient across the whole spectrum of logistics, including maintenance, supply, etc. Whether deployed or in garrison, the Marines on the front lines trust the combat logistics battalions to keep them and their equipment moving.
Supply battalions provide supply support past that of organic unit supply. They provide all assets that a Marine unit might need, excepting fuels, water, and aviation repair parts provided from the Navy. Rations, repair parts, ammunition, personal equipment, and even entire end items are all provided by or through the supply battalions.
Medical battalions provide medical care beyond the immediate care of unit corpsmen. Often, these units act as field hospitals when on deployment. In garrison, they supplement naval hospitals at various Marine installations.
Dental battalions are responsible for the oral health of Marines and Sailors within the MAGTF. On deployment, they can also be used to support field hospitals y when not performing dental roles. In garrison, they run dental health clinics at various Marine installations.
Low Altitude Air Defense Battalions (LAAD) Battalions are tasked with providing ground based air defense in support of the MAGTF. They are also able to be tasked as provisional infantry battalions. They are the only battalion within the Marine Air Wing.
