In addition, all U.S. Marine Corps divisions are capable of, and routinely train for and perform, air assault operations. Forward-deployed Marine Corps infantry battalions/regiments (reinforced, organized, and designated as Battalion Landing Teams/Regimental Combat Teams, or BLTs and RCTs, respectively), form the Ground Combat Element (GCE) of a Marine Expeditionary Unit (MEU), or Marine Expeditionary Brigade (MEB). These MEUs and MEBs are capable of embarking aboard amphibious warships and include air assault as one of several means of conducting amphibious landing operations, supported by embarked Marine Corps tilt-rotor, helicopter, and STOVL fixed-wing strike aircraft.
