The Marine Corps Musician Enlistment Option Program (MEOP) is the central organized body overseeing the active-duty military bands of the United States Marine Corps. Marine Corps field bands can be found in the Southeast United States, Southern California, and the Pacific-Asia region. While serving with their bands, Marines perform throughout the continental United States and travel internationally to locations ranging from Beijing to Paris. These units take part in activities such as retirement ceremonies, the Marine Corps Birthday Ball, funerals, change of commands, and civil/military parades. It is one of two music programs in the Department of the Navy, with the other being Fleet Band Activities.
