The ability of naval expeditionary forces to accomplish their missions is dependent not only on strategy, concepts, and doctrine, but also on the equipment they have available.
Today's naval expeditionary forces provide a first-on-scene, scalable, rapid military response to a range of crises. Considered the world's premier response force, they are unique among even the most powerful navies of the world. A primary focus of the nation's military doctrine, articulated in a wide range of publications—from the National Security Strategy to "Joint Vision 2020"—is forward presence and fighting in and through the littorals. Crises from Bosnia to Somalia, to Liberia and others, have demonstrated that maintaining on-scene Navy and Marine Corps expeditionary forces capable of shaping the nation's strategic environment has never been more important.
