Esta lista de divisiones del ejército de los Estados Unidos se divide en tres épocas: 1911-1917, 1917-1941 y 1941 hasta el presente. Estas eras representan las principales evoluciones de la estructura de la división del ejército (ha habido varios cambios menores durante estos tiempos). La era 1911-1917 enumera las divisiones levantadas durante los primeros intentos del Ejército de modernizar la división, antes de la autorización de las divisiones permanentes, y la era 1917-1941 enumera las primeras divisiones permanentes, antes del advenimiento de las especializadas (blindadas, aerotransportadas, etc. ) divisiones. La era de 1941-presente enumera todas las divisiones organizadas, levantadas o autorizadas desde entonces.

En la medida de lo posible, las divisiones solo se enumeran en las épocas en las que se crearon por primera vez. Algunas divisiones, como la 1ª División de Caballería, se enumeran en varias épocas, ya que sus organizaciones cambiaron drásticamente de una era a la siguiente. Muchas divisiones se superponen a los años enumerados en las categorías de era, principalmente debido a la lentitud con que fueron desactivadas, inactivadas o disueltas de otro modo.

Varias divisiones han existido bajo múltiples designaciones, como la 10ª División de Montaña (10ª División Ligera (Alpina), 10ª División de Infantería). Además, varias divisiones con las mismas designaciones numéricas eran divisiones completamente separadas y no relacionadas (ha habido dos 5tas divisiones, por ejemplo).

Historia [ editar ]

Las divisiones en el ejército de los Estados Unidos han existido desde la Revolución Americana cuando, el 22 de julio de 1775, George Washington organizó tres divisiones en Boston , Massachusetts. Las primeras divisiones estadounidenses, hasta la Guerra Civil estadounidense , eran principalmente organizaciones temporales, y la base del ejército de los Estados Unidos eran brigadas y regimientos.

Durante la Guerra Civil , la guerra en la que se formaron los primeros grandes ejércitos verdaderos en la historia de los Estados Unidos, las divisiones se formaron principalmente para apoyar al cuerpo del ejército , y generalmente se numeraron como 1ra, 2da y 3ra división del cuerpo correspondiente.

El concepto de la división permanente del Ejército de los Estados Unidos se formuló y se puso a prueba a principios del siglo XX. En 1916, la división permanente finalmente sería autorizada por el Congreso , lo que resultó en un cambio dramático en la estructura de fuerzas del Ejército. Por primera vez, la división fue el elemento base del Ejército de los Estados Unidos y permaneció como tal hasta la Guerra Global contra el Terrorismo , cuando el Ejército cambió su énfasis a los equipos de combate de brigada y regimiento .

Desde las autorizaciones de las divisiones permanentes, el Ejército de los Estados Unidos ha levantado 128 divisiones separadas con linajes únicos.

Designaciones [ editar ]

Antes de 1941, solo se designaban específicamente divisiones de caballería ; las divisiones de infantería fueron designadas simplemente por "División". Tras el advenimiento de la división blindada , las divisiones de infantería fueron designadas oficialmente por "División de Infantería" (siendo la 25ª División de Infantería la primera constituida por el ayudante general como tal). Todas las divisiones de 1917-1941 (no de caballería), con las excepciones de las divisiones 10 a 20 y 101, se volverían a designar como divisiones de infantería en algún momento de la era de 1941 hasta la actualidad.

Aparte de las mencionadas divisiones blindadas, de caballería e infantería, las únicas designaciones oficiales de división del ejército son Air Assault (una división de prueba), Airborne , Light (tres divisiones de prueba en la Segunda Guerra Mundial ), motorizada (brevemente autorizada de 1942 a 1943) y Montaña . Para propósitos de linaje, la 101a División Aerotransportada mantiene su designación como división aerotransportada, aunque actualmente está organizada como división de asalto aéreo.

Las divisiones enumeradas con un identificador adicional entre paréntesis ("alpino" o "prueba", por ejemplo) existían solo con ese identificador. Las divisiones que han tenido múltiples identificadores adicionales, como la 1ª Caballería (" aeromóvil ", "pesado") y la 9ª Infantería ("ligera", "motorizada"), quedan sin identificar, independientemente de su identificador adicional actual.

Una división no especificada hoy se refiere a una división de entrenamiento de la Reserva del Ejército de los Estados Unidos .

Divisiones del Ejército de los Estados Unidos (1917 a 1941) [ editar ]

Divisiones de caballería [ editar ]

En 1940, la Guardia Nacional retiró voluntariamente su asignación de las Divisiones de Caballería 21 a la 24, en parte en respuesta a la decisión del Ejército de que la Guardia Nacional no necesitaba cuatro Divisiones de Caballería y la falta de voluntad del Ejército para asignar las divisiones blindadas de la Guardia Nacional. Las divisiones de caballería de la 61 a la 66 se desactivaron en 1942.

Las Divisiones 76 a 91 y 94 a 104 existían principalmente como alojamientos de oficiales con cuadros alistados; no se reactivaron por completo hasta la entrada de Estados Unidos en la Segunda Guerra Mundial.

Las brigadas de infantería, las brigadas de artillería de campaña y varias otras unidades subordinadas de las Divisiones del Canal de Panamá, Hawai y Filipinas se numeraron de acuerdo con lo que deberían haber sido las Divisiones 10, 11 y 12.

Divisions planned but never actually formed during World War II[edit]

At the time of the Japanese attacks on Pearl Harbor, Wake Island, and the Philippines, the United States Army was composed of 37 divisions, including the Philippine Division. Initially, necessary mobilization was estimated to be as high as 350 divisions, but the Army ultimately settled on a 100-division plan.[1]

This relatively low number (compared to the high estimates) was partially due to the army's policy of assigning many combat units, particularly artillery and tank destroyer units, directly to corps and higher-level commands. These non-divisional units numbered approximately 1.5 million soldiers, enough personnel to man roughly 100 more divisions. The strategic philosophy was that such units could be assigned to divisions on an as-needed basis, and would allow divisions to remain as mobile and flexible as possible. By the end of 1943, U.S. Army strength stood at more than 70 divisions.

Allied gains in 1942 and 1943 resulted in a further contraction of U.S. mobilization, and the last wartime division, the 65th Infantry Division, was activated on 16 August 1943. In all, 91 divisions served in the U.S. Army in World War II. When the decision was made to halt the increase in divisions, 12 more divisions were still on the rolls, but would not be organized, though several of these would be organized following the war. They were the 15th Airborne Division, the 18th, 21st and 22nd Armored Divisions, the 19th Armored Division, which was in fact activated following the war, the 61st, 62nd, 67th, 68th, 72nd, 73rd, and 74th Infantry Divisions, and the 105th and 107th Infantry Divisions, which were intended to be Negro formations.

Unique among the 14 unorganized divisions, the 15th Airborne Division was not only a victim of the decision to set the size of the Army at 89 divisions (the 2nd Cavalry Division had been deactivated during the war and the Philippine Division was destroyed as a result of the Japanese victory in the Philippines), but also because it had become evident that the Army Air Forces lacked enough transport aircraft to support a sixth airborne division. The 13th Airborne Division never saw combat for this very reason.

The 105th and 107th Infantry Divisions were to join the 92nd and 93rd Infantry Divisions as Negro divisions. A shortage of manpower resulted in the activation of the 105th and 107th being canceled in 1942.
