3rd Infantry Brigade, 2nd Infantry Division

The brigade was first organized as the 1st Provisional Brigade, a Regular Army unit, at Syracuse, New York, on 11 August 1917. It was redesignated as the 3rd Infantry Brigade of the 2nd Division on 22 September, a day after the latter was constituted.[5]

The 2nd Division was first constituted on 21 September 1917 in the Regular Army.[6][7][8][9] It was organized on 26 October 1917 at Bourmont, Haute Marne, France.[10] At the time of its activation, the Indianhead Division was composed of the 3rd Infantry Brigade, which included the 9th Infantry Regiment; the 23rd Infantry Regiment and the 5th Machine Gun Battalion; the 4th Marine Brigade, which consisted of the 5th Marine Regiment, the 6th Marine Regiment and the 6th Machine Gun Battalion; 2nd Brigade of field artillery; and various supporting units.[3][4] Twice during World War I the division was commanded by US Marine Corps generals, Brigadier General Charles A. Doyen and Major General John A. Lejeune (after whom the Marine Corps Camp in North Carolina is named), the only time in U.S. military history when Marine Corps officers commanded an Army division.[10]

The division spent the winter of 1917–18 training with French and Scottish veterans. Though judged unprepared by French tacticians, the American Expeditionary Force (AEF) was committed to combat in the spring of 1918 in a desperate attempt to halt a German advance toward Paris. Major General Edward Mann Lewis Commanded the 3rd Brigade as they deployed to reinforce the battered French along the Paris to Metz road. The Division first fought at the Battle of Belleau Wood and contributed to shattering the four-year-old stalemate on the battlefield during the Château-Thierry campaign that followed.

On 28 July 1918, Marine Corps Major General Lejeune assumed command of the 2nd Division and remained in that capacity until August 1919, when the unit returned to the US. The division went on to win hard-fought victories at Soissons and Blanc Mont. Finally the Indianhead Division participated in the Meuse-Argonne Offensive which ended any German hope for victory. On 11 November 1918 the Armistice was declared, and the 2nd Division entered Germany, where it assumed occupation duties until April 1919. 2nd Division returned to U.S. in July 1919.

The 2nd Division was three times awarded the French Croix de guerre for gallantry under fire at Belleau Wood, Soissons, and Blanc Mont. This entitles current members of the division and of those regiments that were part of the division at that time (including the 5th and 6th Marine Regiments) to wear a special lanyard, or fourragère, in commemoration. The Navy authorized a special uniform change that allows hospital corpsmen assigned to 5th and 6th Marine Regiments to wear a shoulder strap on the left shoulder of their dress uniform so that the fourragère can be worn.

The division lost 1,964 (including USMC: 4,478) killed in action and 9,782 (including USMC: 17,752) wounded in action.

Upon returning to the United States, the division was stationed at Fort Sam Houston, at San Antonio, Texas as one of three divisions to remain intact and on active duty for the entire interwar period. At this time, Major General Edward Mann Lewis was placed again in Command, this time not only of the Division, but of the Eighth Corps Area. It remained there for the next 23 years, serving as an experimental unit, testing new concepts and innovations for the Army. The 2nd Division stationed at Camp Bullis and Fort Sam Houston, Texas was the first command reorganized under the new triangular concept of organization theory of warfare, which provided for three separate regiments in each division.

Second Division Memorial, dedicated in 1936, is located in President's Park, Washington, D.C.

In the summer of 1954 the 2nd Infantry Division was transferred from Korea to Fort Lewis, Washington, where it remained for only two years, until being transferred to Fort Richardson, Alaska in August 1956. On 8 November 1957, it was announced that the division was to be deactivated. However, a few short months later, in the spring of 1958, the Department of the Army announced that the 2nd Infantry Division would be reorganized at Fort Benning, Georgia, with personnel and equipment of the 10th Infantry Division returning from Germany. Fort Benning remained the home of the new 2nd Infantry Division from 1958 to 1965, where they were initially assigned the mission of a training division. To improve combat readiness, in March 1962 the 2ID was designated as a Strategic Army Corps (STRAC) unit. Following this the division became engaged in intensified combat training, tactical training, and field training exercises, in addition to special training designed to improve operational readiness.

In 1963, the division was reorganized as a Reorganization Objective Army Division (ROAD). Three Brigade Headquarters were activated, including the 3rd Brigade, and Infantry units were reorganized into battalions.

As a result of the formation of the 1st Cavalry Division (Airmobile) at Fort Benning in 1965, the 2nd Infantry Division's stateside unit, along with 11th Air Assault Division's personnel and equipment, were merged to form a new formation, and the existing 1st Cavalry Division in Korea took on the title of the 2nd Infantry Division. Thus the division formally returned to Korea in July 1965. From 1966 onwards the Korean DMZ Conflict (1966–69) increased. On 2 November 1966, soldiers of the 1st Battalion, 23d Infantry Regiment were killed in an ambush by North Korean forces. In 1967 enemy attacks in the Korean Demilitarized Zone (DMZ) increased, as a result, 16 American soldiers were killed that year.

In 1968 the 2nd Infantry Division was headquartered at Tonggu Ri and responsible for watching over a portion of the DMZ.[11] In 1968 North Koreans continued to probe across the DMZ, and in 1969, while on patrol, four soldiers of 3d Battalion, 23d Infantry were killed. On 18 August 1976, during a routine tree-trimming operation within the DMZ, two American officers of the Joint Security Force Archived 15 September 2020 at the Wayback Machine were axed to death in a melee with North Korean border guards called the Axe Murder Incident. On 21 August, following the deaths, the 2nd Infantry Division supported the United Nations Command in "Operation Paul Bunyan" to cut down the "Panmunjeom Tree". This effort was conducted by Task Force Brady (named after the 2nd ID Commander) in support of Task Force Vierra (named after the Joint Security Area Battalion commander).

Congress adopted the Nunn-Warner Amendment to the 1989 Defense Appropriation Bill, which ordered a reduction in U.S. troop strength in Korea from 43,000 to 36,000 by the end of calendar year 1991. As a result, on 16 September 1992, the 2nd Infantry Division's 3rd Brigade was inactivated at Camp Howze.

To complete the 2nd Infantry Division with a third brigade, the 3d Brigade, 1st Armored Division, and an associated 'slice' of the division's supporting units from Bad Kreuznach, Germany, was to be returned home and stationed at Fort Lewis, Washington. However, when the move was completed in September 1994, the 4,000 3rd Brigade soldiers (still part of the 1st Armored Division) were separated from their new parent division. As a result, they were organized as a split-based brigade combat team (BCT).

On 29 March 1995, the 3rd Brigade, 2nd Infantry Division was reactivated at Fort Lewis, effectively 'reflagged' from the 3d Brigade, 1st Armored Division. It was composed of the 1-23 Infantry, 1-32 Armor, 1-33 Armor, 1-37 Field Artillery, 168 Engineer, the 296th Forward Support Battalion, and Charlie Battery 5-5 Air Defense Artillery. Other sources have 16 April 1995 as the official reactivation date.

From November 2003 to November 2004, the 3rd Stryker Brigade Combat Team deployed from Fort Lewis, Washington in support of Operation Iraqi Freedom. In the sands of Iraq the 3rd Brigade Stryker Brigade Combat Team proved the value of the Stryker brigade concept in combat and logistics operations.[12]

From June 2006 to September 2007, the 3rd Stryker Brigade Combat Team deployed from Fort Lewis, Washington in support of Operation Iraqi Freedom. During the 3rd Stryker Brigade's second deployment to Operation Iraqi Freedom their mission was to assist the Iraqi security forces with counter-insurgency operations in the Ninewa Province. Following a second RIP (Relief in Place) with 172nd SBCT, the BDE split between the bridge proper and 1st BDE, 1st CAV DIV. The respective units were based out of Balad, Taji, and Greater Baghdad. The bulk of the 46 soldiers that were killed in action during the deployment, occurred during this time frame.

On 1 June 2006 at Fort Lewis, Washington the 4th Brigade, 2d Infantry Division was formed. From April 2007 to July 2008 the 4th Stryker Brigade Combat Team was deployed in as part of the surge to regain control of the situation in Iraq. The brigade assumed responsibility for the area north of Baghdad and the Diyala province. 35 soldiers from the brigade were killed during the deployment.

From October 2006 to January 2008, the 2nd Infantry Brigade Combat Team deployed from Fort Carson, Colorado in support of the Multi-National Division – Baghdad (1st Cavalry Division) and was responsible for assisting the Iraqi forces to become self-reliant, bringing down the violence and insurgency levels and supporting the rebuilding of the Iraqi infrastructure. 43 soldiers from the brigade were killed during the deployment.

SSG Christopher B. Waiters of 5th Battalion, 20th Infantry Regiment, 3d Brigade Combat Team was awarded the Distinguished Service Cross on 23 October 2008 for his actions on 5 April 2007 when he was a specialist. Shortly after, SPC Erik Oropeza of the 4th Battalion, 9th Infantry Regiment, 4th Brigade Combat Team[13] Thus the division will be credited with the 17th and 18th Distinguished Service Cross awardings since 1975.

On 17 February 2009, President Barack Obama ordered 4,000 soldiers from the 5th Stryker Brigade Combat Team to Afghanistan, along with 8,000 Marines. Soldiers are being sent there because of the worsening situation in the Afghan War. These soldiers were deployed in the southeast, on the Afghanistan-Pakistan border. During deployment, 35 soldiers were killed in combat, two others were killed in accidents, and 239 were wounded.[15] In July 2010, the 5th Stryker Brigade Combat Team was inactivated and reflagged as the 2nd Stryker Brigade Combat Team. The brigade's Special Troops Battalion was also inactivated and reflagged and the rest of the subordinate units were reassigned to the reactivated 2nd SBCT.[16]

3rd SBCT deployed in December 2011 and served in Afghanistan for one-year. 16 soldiers from the brigade lost their lives during the deployment.[17][18] They were joined by their sister Stryker brigade, the 2nd SBCT in the spring[19] 2nd Brigade returned around December 2012 and January 2013 having lost eight soldiers during deployment. The 4th Stryker BCT also deployed to its first deployment to the country in fall 2012 and returned in summer 2013 having lost four soldiers.[20]

On 5 September 2015, the Army retired the 3rd Brigade, 2nd Infantry Division flag, and the unit was re-designated as the 1st Brigade, 2nd Infantry Division.[21]
