The MEU is unique in that its air and ground combat elements are combined with a logistics combat element under one commander; other services do not unite the command of air and ground forces until much higher command levels.
When the United States Army integrates with Air Force assets, it typically is at the theater or corps level, with a general commanding, while at the division level it will integrate with Army aviation, which can be organized as organic at the battalion level.
The MEU's ground combat element also combines artillery, light armor and tanks at a much lower level than was common in the Army until the development of the brigade combat team early in the War on Terror, with a similar concept, the combat command, being utilized in World War II.
This air-ground task force concept is designed to thoroughly exploit the combat power inherent in air and ground assets by closely integrating them into a single force. The MEU brings all the supplies and logistical support it needs to sustain itself for quick mission accomplishment or to pave the way for any follow-up forces. This self-sustainment allows more flexibility in disposition and operations of forces, and allows the MEU to initiate operations sooner and let support catch up later, without having to wait for external logistical support to begin a mission. Deployments on U.S. Navy amphibious assault ships allows MEUs to seabase around the globe, ready for deployment at short notice.
A typical MEU has approximately 2,200 Marines and sailors. It is equipped with:
