The USMC Mission The primary mission of the Marine Corps is to provide Fleet Marine Forces of combined arms together with supporting air components, for service with the fleet. The USMC is organized as a rule of three. The Marine Corps minimum peacetime structure shall consist of not less than three combat divisions and three aircraft wings, and land combat, aviation, and other services as needed. The Marine Corps maintains a fourth Marine division and aircraft wing in reserve. The rule of three is passed down the c hain of command as well. Basically, each Marine has three things to worry about. Three men to a fire team commanded by a Corporal (so there are actually a total of four on the team when you count the team leader). Three fire teams to a rifle squad commanded by a sergeant. Three rifle squads to a platoon commanded by a Lt. Three rifle platoons to a company commanded by a Capt.

MEU In addition to the above, there are also MEUs (Marine Expeditionary Unit). With a strength of about 2,200 personnel, the MEU is normally built around a reinforced battalion, a composite aircraft squadron, and by a MEU Service Support group. Commanded by a colonel, the MEU is employed to fulfill routine forward deployments with fleets in the Mediterranean, the Western Pacific, and periodically, the Atlantic and Indian Oceans. The MEU is deployed on up to four Naval amphibious ships. The ground combat element (GCE) is the battalion landing team (BLT), an infantry battalion reinforced with artillery, amphibious assault vehicles, light armored reconnaissance assets and other units as the mission and circumstances require.

The combat service support element is the MEU Service Support Group (MSSG) formed primarily from force service support groups assets. The MSSG contains all the logistics specialists necessary to keep the GCE, ACE and organic equipment functioning. Included within the MSSG are medical, dental, maintenance, engineering, and other technical experts. The command element (CE) provides command and control of the other three elements. In addition to the MEU commander and his supporting staff, the CE includes specialized detachments providing a direct action capability, naval gunfire liaison capability, reconnaissance, and surveillance and specialized communications and electronics warfare capabilities.
