Editing Corps (section)

=====Cold War and 21st century=====
After the [[Korean War]], the Army and Marines diverged in their approach to the concept of the field corps. The Army continued to group its divisions into traditional corps organizations in the Continental United States (CONUS), West Germany ([[V Corps (United States)|V Corps]] and [[VII Corps (United States)|VII Corps]]), and South Korea (I Corps). However, during the [[Vietnam War]], the Army designated its corps-level headquarters in South Vietnam as [[I Field Force|I&nbsp;Field Force]] and [[II Field Force|II&nbsp;Field Force]] to avoid confusion with the [[Army of the Republic of Vietnam|ARVN]] corps areas.<ref name=Eck-VN-C&C>{{cite book|last1=Eckhardt|first1=George S.|title=Vietnam Studies: Command and Control, 1950-1969|date=1991|publisher=Department of the Army|location=Washington, DC|pages=52–55|url=http://www.history.army.mil/books/Vietnam/Comm-Control/|access-date=30 July 2014|archive-date=18 March 2014|archive-url=https://web.archive.org/web/20140318150728/http://www.history.army.mil/books/Vietnam/Comm-Control/|url-status=dead}}</ref> As of July 2016, the Army deactivated all corps headquarters save three CONUS based corps ([[I Corps (United States)|I Corps]] - Washington, [[III Corps (United States)|III Corps]] - Texas, and [[XVIII Airborne Corps]] - North Carolina).

In the 1960s, the Marine Corps activated the [[I Marine Expeditionary Force]] (I MEF) on Okinawa (based in California since 1971) and [[II Marine Expeditionary Force]] (II MEF) in North Carolina, and re-activated the III Amphibious Corps (which had been deactivated in 1946) as [[III Marine Expeditionary Force]] (III MEF) in South Vietnam (re-deployed to Okinawa in 1971). In 1965, all three MEFs were subsequently re-designated as Marine amphibious forces or MAFs, and in 1988 all three Marine Corps corps-level commands were again re-designated as [[Marine expeditionary force]]s (MEF). The MEF had evolved into a self-contained, corps-level, [[Marine air-ground task force]] (MAGTF) consisting of a MEF headquarters group, a Marine division, a Marine aircraft wing, and a force service support group (re-designated as Marine logistics group in 2005).
