The Marine Expeditionary Unit (MEU) provides an immediate reaction capability for crisis response and is capable of limited combat operations. Selective, timely and credible commitment of air-ground units have brought stability to regions and sent signals world-wide to aggressors that the United States is not only willing to defend its interests, but able to do so with a significantly powerful force of extremely short notice. The MEU is the smallest of the MAGTFs. Together, with its Navy brethren they serve as the Nation's forward deployed, quick response team, capable of accomplishing numerous missions around the globe. The MEU, Commanded by a Marine Colonel, is comprised of approximately 2,200 Marines and Sailors embarked aboard three or four amphibious ships. These ships are manned by another 2100-2300 Marines / Sailors and as a group are designated as an Amphibious Squadron (PHIBRON) commanded by a senior Navy Captain, who bears the title of Commodore.
