The Ground Combat Element (GCE), comprised 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 (including EOD), 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.
