is normally built around a division/wing team, but can include several divisions and
aircraft wings, together with an appropriate combat service support organization. The
Marine expeditionary force is capable of conducting a wide range of amphibious assault
operations and sustained operations ashore. It can be tailored for a wide variety of
combat missions in any geographic environment. Also called MEF. See also Marine air-ground
