The Marine Raiders were elite units established by the United States Marine Corps during World War II to conduct special amphibious light infantry warfare, particularly in landing in rubber boats and operating behind the lines. “Edson’s” Raiders of 1st Marine Raiders Battalion and “Carlson’s” Raiders of 2nd Marine Raiders Battalion are said to be the first United States special operations forces to form and see combat in World War II.
However, despite the original intent for Raiders to serve in a special operations capacity, most combat operations saw the Raiders employed as conventional infantry. This, combined with the resentment within the rest of the Marine Corps that the Raiders were an “elite force within an elite force”, led to the eventual abandonment of the experiment.
Four Raider battalions served operationally but all were disbanded on 8 January 1944 when the Corps made the doctrinal decision that the Raiders had outlived their original mission. In 2014, the Marine Special Operations Regiment, serving under the United States Marine Corps Forces Special Operations Command (MARSOC), was renamed the Marine Raider Regiment. This change was implemented to better show that modern Marine special operations forces trace their lineage and heritage back to the World War II Raiders. Individual marines of the Marine Raider Regiment are once again called “Marine Raiders”.
