Examples of Army corps
The Union Army during the American Civil War: The Union Army created the Army Corps structure to better manage large groups of troops. The Army of the Potomac, the main Union fighting force, was divided into several Army Corps, with each corps consisting of two to four divisions containing multiple brigades. Major generals commanded these corps, while Lieutenant generals commanded the entire Army. One famous corps in the Union Army was the II Corps, commanded by Major General Winfield Scott Hancock, which played a significant role in the Battle of Gettysburg.
The German Army during World War II: In World War II, the German Army (Wehrmacht) utilized the corps structure to organize its forces. One notable corps was the Afrika Korps, led by General Erwin Rommel, which fought in North Africa against British and American forces. The Afrika Korps consisted of several divisions, including the 15th Panzer Division and the 21st Panzer Division, and played a crucial role during battles such as the Battle of El Alamein.
The US Army during the Vietnam War: The US Army employed numerous corps during the Vietnam War to better coordinate and manage its forces. One example was the I Field Force, Vietnam (IFFV), commanded by Lieutenant General Stanley R. Larsen and later Major General Charles A. Corcoran. IFFV managed US and allied forces in the highlands of South Vietnam, consisting of several divisions and brigades, including the 4th Infantry Division, the 173rd Airborne Brigade, and the 1st Brigade, 101st Airborne Division. The corps was responsible for both regionally-focused counter-insurgency missions and major search and destroy operations.
