U.S. Third Army

U.S. Third Army. The U.S. Third Army is a field army of the United States Army, currently serving as the Army Service Component Command for United States Army Central. It is one of the most storied formations in American military history, renowned for its decisive role in the European Theater during World War II under the legendary command of George S. Patton. Throughout its history, it has participated in major conflicts including World War I, the Cold War, the Gulf War, and the post-9/11 wars in Iraq and Afghanistan.

History

The Third Army was first activated in 1918 at Chaumont, France, during World War I under the command of Joseph T. Dickman. It played a key role in the final Meuse-Argonne Offensive, the largest American operation of the war, which helped force the Armistice of 11 November 1918. Following the war, it was involved in occupation duties before being deactivated in 1919. The army was reactivated in 1932 at Fort Sam Houston in Texas and was initially commanded by Walter Krueger, focusing on training and large-scale exercises in the pre-war period.

World War II

The Third Army's most famous chapter began after the Normandy landings, when it became operational under George S. Patton in August 1944. Leading the rapid Operation Cobra breakout, its forces executed a spectacular advance across France, famously relieving besieged American troops during the Battle of the Bulge at Bastogne. Its drive across the Rhine at Oppenheim and subsequent thrust through Germany and into Czechoslovakia was marked by incredible speed and aggression. Key subordinate units included the VIII Corps, XII Corps, XV Corps, and XX Corps, which comprised divisions like the 4th Armored Division and the 80th Infantry Division.

Post-World War II and Cold War

After Victory in Europe Day, the Third Army assumed occupation duties in Germany before returning to the United States. It was headquartered at Fort McPherson, Georgia, and served as a key training and readiness command during the Cold War. It provided forces for the Korean War and the Vietnam War, though it did not deploy as a whole. The army later played a central role in the rapid deployment of forces to the Middle East, a mission that culminated in its leadership of CENTCOM's land forces during the Gulf War, notably commanding the famed "Left Hook" maneuver by the VII Corps and XVIII Airborne Corps.

Structure and organization

Today, as the Army Service Component Command for United States Army Central, the Third Army is responsible for coordinating and providing land forces to the United States Central Command area of responsibility, which spans the Middle East, Central Asia, and parts of South Asia. Its headquarters is at Shaw Air Force Base, South Carolina. Its structure is modular, designed to command a variable number of corps, divisions, and brigade combat teams deployed from across the United States Army Forces Command and the Army National Guard.

Commanders

Notable commanders have shaped the army's legacy across different eras. Its first commander was Joseph T. Dickman in World War I. Walter Krueger commanded during its interwar reactivation. Its most iconic leader was George S. Patton, whose tenure defined its World War II success. He was succeeded by Lucian Truscott. In the modern era, commanders like John W. Vessey Jr., who later became Chairman of the Joint Chiefs of Staff, and Paul J. Kern have led the organization through the post-Cold War period and the Global War on Terrorism.

Campaigns and operations

The Third Army's battle honors include the World War I Victory Medal for the Meuse-Argonne Offensive. In World War II, it earned campaign participation credit for Northern France, the Rhineland, the Ardennes-Alsace, and Central Europe. In the modern era, it was the lead land component command for Operation Desert Storm during the Gulf War. It later commanded coalition ground forces during Operation Iraqi Freedom and provided critical support for Operation Enduring Freedom in Afghanistan.
