Which Marine Expeditionary unit has a sustainment duration of 15 days?

The Marine Expeditionary Unit (MEU) is designed for quick response to a variety of missions, including humanitarian assistance and combat operations. One of its key characteristics is its sustainment duration, which is typically structured to last for up to 15 days. This makes MEUs highly flexible and capable of maintaining operations in the field without immediate resupply, thus allowing them to respond swiftly to emerging situations or crises.

The structure and resources of the MEU are specifically organized to support this 15-day sustainment, which includes supplies, equipment, and personnel tailored to provide a balanced mix of capabilities. This ensures that the MEU can effectively accomplish its assigned missions during the initial phase of any operation.

In contrast, other units such as the Marine Expeditionary Force and Marine Expeditionary Brigade have different operational scopes and sustainment capabilities that exceed the duration typical of a MEU, while the Marine Expeditionary Command primarily facilitates command and control rather than direct deployment on the ground. Understanding these distinctions helps clarify the unique role of the Marine Expeditionary Unit within the broader context of Marine Corps operations.
