Honing Lethality: 31st Marine Expeditionary Unit Completes MEU Exercise

22 Jan 2020 | Lance Cpl. Kolby Leger 31st Marine Expeditionary Unit

During the regularly-scheduled exercise after the Battalion Landing Team’s relief-in-place, components of the 31st MEU planned and executed full-mission profiles. The exercise is designed to simulate missions that the MEU could be tasked with at any moment by the geographic combatant commander, and to improve the unit’s lethality and readiness. MEUEX missions range from small boat raids including a Marine amphibious force riding combat rubber raid craft to clandestinely insert on shoreline objectives, to company-sized expeditionary advanced airfield seizures using a vertical-assault force in MV-22B Osprey tiltrotor aircraft, and CH-53E Super Stallion heavy-lift helicopters, prior to establishment of forward arming and refueling points for follow-on operations.

“We are continuously ready as a globally-deployable unit prepared for crisis, and the MEU Exercise sharpens our lethal edge.” Col. Robert Brodie, 31st MEU commanding officer


Throughout the scenario, the 31st MEU commanding officer and staff convened crisis action teams to assess the dynamic situation, problem-framed, and wargamed then selected courses of action. Mission commanders planned and briefed the mission sets to achieve the overall commander’s intent.

This rapid response planning process, designed to take six hours from start to finish, is crucial in planning to execution processes as key to the 31st MEU’s mission accomplishment. By launching missions in and around Okinawa, Japan, and simulating ship-to-shore movements, MEUEX prepared the Marine Air-Ground Task Force for planning and integration with naval partners.

Marines and Sailors with the 31st MEU regularly embark aboard the ships of PHIBRON-11, forward-based in Sasebo, Japan, for deployments and at-sea periods. The 31st MEU will continue to focus on area presence throughout the Indo-Pacific region, training with allied and partner nations’ militaries in order to enhance security, support freedom of navigation, and serve as an expeditionary crisis response force.

According to Col. Robert Brodie, 31st MEU commanding officer, MEUEX is key to maintaining the MEU’s constant state of combat readiness.

The 31st MEU, the Marine Corps’ only continuously forward deployed MEU, provides a flexible and lethal force ready to perform a wide range of military operations as the premier crisis response force in the Indo-Pacific region.
