In the United States Marine Corps, the ground combat element (GCE) is the land force of a Marine Air-Ground Task Force (MAGTF). It provides power projection and force for the MAGTF. Role within the MAGTF The ground combat element (GCE), composed primarily of infantry units (infantry battalions organized into battalion landing teams, regimental combat teams, and Marine divisions). These organizations contain a headquarters unit that provides command and control (management and planning for manpower, intelligence, operations and training, and logistics functions) as well as scout/sniper, aviation liaison/forward air controller, NBC defense, communications, service (supply, motor transport, weapons maintenance, and dining facility), and Navy combat medical and chaplain's corps personnel. The GCE also contains combat support units, including artillery, armor (tank, assault amphibian, and light armored reconnaissance), combat engineer, and 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 Battalions As the largest component of the GCE, Marine infantry is essentially multi-purpose, heavily manned and equipped, light infantry (e.g., a Marine rifle squad having 13 Marines, vs. nine soldiers in an U.S. Army rifle squad). With three rifle companies that are over 40% larger, plus a weapons company, and an additional 100 members in its Headquarters and Service Company (as compared to the TO&E of an Army light infantry battalion), 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 (BLT) are also very heavily supported (as compared to Army light infantry) 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 (including one each of amphibious assault vehicles, main battle tanks, and light armored reconnaissance vehicles), 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 (AAV-P7-A1), Landing Craft Air Cushion (LCAC), Rigid-Hulled Inflatable Boat (RHIB/RIB), Rigid buoyant boat (RBB), or conventional landing craft such as the Landing Craft Utility (LCU 1466/1610/1627) and Landing Craft Mechanized (LCM-8), etc. In addition, all Marine infantry units are prepared, and regularly train, to perform heliborne, or
