The rise of networked enemy surveillance systems and long-range precision strike capabilities make Marine expeditionary unit (MEU)-centered amphibious ready groups (ARGs) too large to avoid attention, and they are too few in number to carry out widely dispersed missions. U.S. amphibious warfare needs a real innovation in how Marines are put ashore, using new technology and perhaps some old ideas to help Marines carry out new ways of achieving objectives.
According to “Expeditionary Force 21” (EF21), “the increased range, precision, and proliferation of antiaccess/area denial (A2/AD) systems highlight the need to conduct dispersed operations with smaller, task-organized forces. While EF21 seeks to carry out traditional Marine missions in the new threat environment of this century, there is a danger of not adapting fast enough. The operating concept risks failure if the Marine Corps does not push adaptation ruthlessly tested into the force.1
