Sgt. Maj. Jim Lanham, sergeant major of the 31st Marine Expeditionary Unit, speaks to 31st MEU Marines attending Corporal's Course aboard the USS Green Bay (LPD 20), Pacific Ocean, Sept 10, 2016. Corporal's Course is designed to train the Marine Corps' junior noncommissioned officers in new skills and becoming more effective leaders. The 31st MEU is the Marine Corps’ only continuously forward-deployed Marine Air-Ground Task Force, and combines air-ground-logistics into a single team capable of addressing a range of military operations in the Asia-Pacific region, from force projection and maritime security to humanitarian assistance and disaster relief.
