There was a time when the U.S. Marine Corps was inseparable from the U.S. Navy, with a lethal naval expeditionary force designed for the naval campaigning through a single battle concept. However, as an indirect consequence of extended land-based combat operations in Iraq and Afghanistan, the Marine Corps has developed an institutional habit of working ashore for land commanders, while at the same time tacitly sanctioning the atrophy of the skills required for naval expeditionary operations. With the exception of Amphibious Ready Groups (ARGs) and Marine Expeditionary Units (MEUs), the Navy has developed the practice of working without Marines, which, over time, has drawn it away from the littorals and into the deep waters of the oceans.
