A MEF consists of which subordinate commands?

A Marine Expeditionary Force (MEF) is a combined arms task organization designed to conduct a wide variety of operations. It consists of a ground combat element (GCE), an aviation combat element (ACE), a logistics combat element referred to as the Combat Service Support Element (CSSE), and a command element (CE). Each of these subordinate commands plays a crucial role in ensuring the MEF can operate effectively and efficiently.

The command element (CE) serves as the headquarters, providing command and control, logistical support, and coordination for all units within the MEF. The aviation combat element (ACE) supports ground operations through air support, transportation, and logistics. The ground combat element (GCE) consists of Marine ground troops organized to close with and destroy the enemy, while the CSSE focuses on the logistical aspects, ensuring that the Marines have the necessary support and supplies to carry out their missions.

Understanding the composition of a MEF and the specific roles of each subordinate command is essential for effective joint operations and mission planning within the fleet marine forces.
