Ground combat element
In the United States Marine Corps, the ground combat element is the land force of a Marine Air-Ground Task Force. It provides power projection and force for the MAGTF.
Role within the MAGTF
The ground combat element, composed primarily of infantry units. These organizations contain a headquarters unit that provides command and control as well as scout/sniper, aviation liaison/forward air controller, nuclear/biological/chemical defense, communications, service, and Navy combat medical and chaplain's corps personnel. The GCE also contains combat support units, including artillery, armor, combat engineer, and United States [Marine Corps Reconnaissance Battalions|reconnaissance] units. At the division level, the GCE also contains limited organic combat service support, including a truck company, a military police/law enforcement company, and the division band.U.S. Marine Corps Infantry
Marine Infantry BattalionsAs the largest component of the GCE, Marine infantry is essentially multi-purpose, heavily manned and equipped, light infantry. With three rifle companies that are over 40% larger, plus a weapons company, and an additional 100 members in its Headquarters and Service Company, the Marine infantry battalion contains approximately 970 members as compared to approximately 560 in an Army light infantry battalion.
Marine infantry battalions that are reinforced to form a Battalion Landing Team are also very heavily supported with additional organic assets. This combat support includes: a field artillery howitzer battery containing a firing platoon of six 155mm howitzers, plus three reinforced armored vehicle platoons, and one platoon each of infantry reconnaissance and combat engineers.
While primarily trained, organized and equipped to be foot-mobile, Marine infantry is of course, prepared to execute amphibious operations, either by Amphibious Assault Vehicle, Landing Craft Air Cushion, Rigid-Hulled Inflatable Boat, Rigid buoyant boat, or conventional landing craft such as the Landing Craft Utility and Landing Craft Mechanized, etc. In addition, all Marine infantry units are prepared, and regularly train, to perform heliborne, or "vertical envelopment" operations when supported by MV-22 medium tiltrotor and/or CH-53 heavy helicopters and mechanized operations. Additionally, some Marine infantrymen attend U.S. Army Airborne or Ranger training. However, since the USMC does not maintain either airborne or Ranger infantry units, only a relatively small number of Marines ever attend these two schools.
Furthermore, while not designated as special operations forces, deployed Marine Expeditionary Units are certified as capable of performing some ""special operations"" type missions. In addition to significant differences between Marine infantry and their US Army counterparts in training and organization, there are some differences in individual weapons, equipment, and vehicles, as well.
The Marine Corps conducts infantry training at three locations:
- The Basic School, Marine Corps Base Quantico, VA
- School of Infantry, Camp Lejeune, NC
- School of Infantry, Camp Pendleton, CA
Current Marine Infantry Organization
Organization
The size of the GCE varies in proportion to the size of the MAGTF. A Marine Expeditionary Force has a division. A Marine Expeditionary Brigade holds an infantry regiment, reinforced with equipment and personnel from various divisional combat support regiments and battalions. The various Marine Expeditionary Units command a reinforced infantry battalion, which includes various combat support unit attachments. Generally, MEF postings are permanent, while MEBs and MEUs rotate their GCE, ACE, and LCE twice annually.Hierarchy of Marine ground units
