This is a list of formations of the United States Army during the World War II . Many of these formations still exist today, though many by different designations. Included are formations that were placed on rolls, but never organized, as well as "phantom" formations used in the Allied Operation Quicksilver deception of 1944—these are marked accordingly.
Airborne, armored, cavalry, infantry, and mountain divisions are grouped separately. The numbering system for the airborne and mountain divisions are a continuation of the infantry numbering system—"phantom" formations are an exception to that numbering system.
A division is a large military unit or formation, usually consisting of between 10,000 and 25,000 soldiers. In most armies, a division is composed of several regiments or brigades; in turn, several divisions typically make up a corps.
The VII Army Corps of the United States Army was one of the two principal corps of the United States Army Europe during the Cold War. Activated in 1918 for World War I, it was reactivated for World War II and again during the Cold War. During both World War II and the Cold War it was subordinate to the Seventh Army, or USAREUR and was headquartered at Kelley Barracks in Stuttgart, West Germany, from 1951 until it was redeployed to the US after significant success in the Gulf War in 1991, then inactivated in 1992.
The 9th Armored Division was an armored division of the United States Army during World War II. In honor of their World War II service, the 9th was officially nicknamed the "Phantom Division."
The 9th Infantry Division is an inactive infantry division of the United States Army. It was formed as the 9th Division during World War I, but never deployed overseas. In later years it was an important unit of the U.S. Army during World War II and the Vietnam War. It was also activated as a peacetime readiness unit from 1947 to 1962 at Fort Dix, New Jersey, and Fort Carson, Colorado, and from 1972 to 1991 as an active-duty infantry division at Fort Lewis, Washington. The division was inactivated in December 1991.
The United States Cavalry, or U.S. Cavalry, was the designation of the mounted force of the United States Army. The United States Cavalry was formally created by an act of Congress on 3 August 1861 and ceased as a distinct Army branch in 1942. The name "cavalry" continues to be used as a designation for various specific United States Army formations and functions.
The United States Army Forces Command (FORSCOM) is the largest United States Army command. It provides expeditionary, regionally engaged, campaign-capable land forces to combatant commanders. Headquartered at Fort Liberty, North Carolina, FORSCOM consists of more than 750,000 active Army, U.S. Army Reserve, and Army National Guard soldiers. FORSCOM was created on 1 July 1973 from the former Continental Army Command (CONARC), who in turn supplanted Army Field Forces and Army Ground Forces.
The United States Army Regimental System (USARS) is an organizational and classification system used by the United States Army. It was established in 1981 to replace the Combat Arms Regimental System (CARS) to provide each soldier with continuous identification with a single regiment, and to increase a soldier's probability of serving recurring assignments with their regiment. The USARS was intended to enhance combat effectiveness by providing the opportunity for a regimental affiliation, thus obtaining some of the benefits of the traditional regimental system.
Shoulder sleeve insignia (SSI) are cloth emblems worn on the shoulders of US Army uniforms to identify the primary headquarters to which a soldier is assigned. The SSI of some army divisions have become known in popular culture.
This list of United States Army divisions is divided into three eras: 1911–1917, 1917–1941, and 1941–present. These eras represent the major evolutions of army division structure. The 1911–1917 era lists divisions raised during the Army's first attempts at modernizing the division, prior to the authorization of permanent divisions, and the 1917–1941 era lists the first permanent divisions, prior to advent of specialized divisions. The 1941–present era lists all of the divisions organized, raised, or authorized since then.
The 68th Armor Regiment is an armored regiment of the United States Army. It was first activated in 1933 in the Regular Army as the 68th Infantry Regiment.
In the United States (US) military, a beret flash is a shield-shaped embroidered cloth that is typically 2.25 in (5.72 cm) tall and 1.875 in (4.76 cm) wide with a semi–circular base that is attached to a stiffener backing of a military beret. These flashes—a British English word for a colorful cloth patch attached to military headgear—are worn over the left eye with the excess cloth of the beret shaped, folded, and pulled over the right ear giving it a distinctive appearance.
The V Army Corps was one of three corps the Italian Army fielded during the Cold War. Based in the regions of Veneto and Friuli-Venezia-Giulia the corps was the army's main combat force. The 5th Army Corps was arrayed close to the Yugoslavian border and tasked with meeting any Warsaw Pact forces that crossed the border. On the left flank of the corps the 4th Alpine Army Corps was tasked with blocking the Alpine passes and in the rear of the corps the 3rd Army Corps served as operational reserve. After the end of the Cold War the corps was reduced in size and on 1 October 1997 it became the 1st Defence Forces Command. In 2013 the COMFOD 1° was disbanded and its function and brigades taken over by the 20th Infantry Division Friuli in Florence.
