Who is in command of a MEB?

A Marine Expeditionary Brigade (MEB) is a significant tactical organization within the Marine Corps, typically consisting of approximately 14,000 to 17,000 Marines and Sailors. The command of a MEB is primarily held by a Brigadier General or a Major General. This rank is suitable for the complex responsibilities involved in leading a MEB, which include coordinating various units and integrating their capabilities during a combined arms operation.

The scale and operational requirements of a MEB necessitate a command-level officer who possesses not only tactical acumen but also extensive leadership experience, making the Brigadier or Major General the most fitting choice for this command role. Their higher rank reflects both their extensive experience and the strategic importance of the missions often assigned to a MEB.

While a Colonel and a Lieutenant Colonel may command smaller units such as battalions or regiments, the scope and authority required to lead a MEB surpass what is appropriate for these ranks. Therefore, the command structure is designed to ensure that only officers of sufficient rank and experience lead such significant formations.
