World War I

Second Army's task during the First World War was to hold the line a short distance east of the Moselle River in France following the end of the Saint-Mihiel offensive along the Western Front. The army was also tasked with reinforcing units from the active-in-combat soldiers of the U.S. First Army.

On November 9, 1918, Second Army was responsible for a frontline sector of 50 kilometers, held by four divisions totaling 43,000 men.[3] These divisions from left to right were the 33rd Division (Illinois Army National Guard), 28th Division (Pennsylvania National Guard), U.S. 7th Division (a regular formation) and 92nd Division (a Colored formation). In reserve were the 4th Division (a regular formation) and the 35th Division (Missouri and Kansas National Guard). One brigade of the 88th Division, a National Army formation raised in Minnesota and North Dakota, had just arrived at the front.

On 10 November, Second Army advanced on German positions, already in disorder and retreating. Word did not reach the units advancing until after eleven-hundred hours on 11 November, making it one of the last formations to fight to the very conclusion of the war. On 15 April 1919, Second Army was deactivated.

World War II

Second United States Army was reactivated on 1 October 1933 under a plan developed by then-Army Chief of Staff Douglas MacArthur to consolidate forces in the continental United States under four regional army commands.[4] It was headquartered in Memphis, Tennessee. In 1940, with the activation of Army General Headquarters (succeeded by Army Ground Forces in 1942), the four field armies were given responsibility for training forces in their respective areas and conducting maneuvers to evaluate training and readiness. In September 1941, Second U.S. Army participated in large-scale maneuvers pitting it against Third United States Army in what were known as the Louisiana Maneuvers.[5] Over 350,000 troops took part. Also in 1941, four regional defense commands were established coterminous with the army areas, and the Commander, Second U.S. Army became also Commanding General, Central Defense Command.

With First and Fourth Armies given primary responsibility for defense of the eastern and western coasts of the United States, and later with First Army's relocation to England to command U.S. Army forces in the invasion of France, Second and Third Armies assumed increasing responsibility for the training and organization of the rapidly expanding army and preparing troops for overseas deployment. When Third Army headquarters was relocated to France in 1944 to serve as a combat command, Second Army assumed its stateside responsibilities as well.

Second U.S. Army was commanded from 1940 to 1943 by Lt. Gen. Ben Lear. He was succeeded by Lt. Gen. Lloyd Fredendall after Fredendall's removal from command in North Africa. General Fredendall held command until war's end.

Post-World War II

In November 1964, as an effort to reorganize military operations, the Department of the Army announced the closure of Fort Jay at Governors Island New York and the relocation of U.S. First Army to Fort Meade, Maryland. First and Second Armies would merge and Second Army subsequently inactivated. It had been proposed that First Army be inactivated, but its commander Lt. General Robert W. Porter, Jr. strongly protested the proposal and it was dropped. In the end, Second Army headquarters staff were retained and became the new staff for U.S. First Army. On 1 January 1966 at Fort Meade, Second Army was deactivated and its colors cased by commander, Lt. General William F. Train who then assumed command of U.S. First Army.

Second Army was reactivated on 1 October 1983 under U.S. Army Forces Command as a regional command to control Army Reserve forces in the southeastern United States, including Puerto Rico and the U.S. Virgin Islands. It was headquartered at Fort Gillem, Georgia. It was again deactivated on 3 July 1995 with First Army once again assuming its functions. First Army was then relocated to Fort Gillem.


On 1 October 2010, Second Army was again re-activated as Signal Corps.[2]

Among ARCYBER/Second Army's subordinate formations are Army Network Enterprise Technology Command / 9th Army Signal Command, the 1st Information Operations Command (Land), and the United States Army Intelligence and Security Command.[6]
