3rd Infantry Brigade, 2nd Infantry Division

At the time of its activation, the 2nd Infantry 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.

World War I
The 2nd Division was first constituted on 21 September 1917 in the Regular Army. It was organized on 26 October 1917 at Bourmont, Haute Marne, France. 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. 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.

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.

After World War I, a memorial was built on Hill 204, 2 miles (3 km.) west of the town for which it is named. The Château-Thierry Monument, designed by Paul P. Cret of Philadelphia, was constructed by the American Battle Monuments Commission "to commemorate the sacrifices and achievements of American and French fighting men in the region, and the friendship and cooperation of French and American forces during World War I."

Interwar years
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 the Division, but the 8th 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. Indianhead soldiers pioneered concepts of air mobility and anti-tank warfare, which served the army for the next two decades on battlefields in every corner of the globe.

The 2nd Division started participated in maneuvers at Christine, Texas between 3 and 27 January 1940. It then moved to Horton, Texas for maneuvers from 26 April to 28 May 1940, followed by maneuvers at Cravens, Louisiana from 16 to 23 August 1940. It returned to Fort Sam Houston, where it continued training and refitting, until it moved to Brownwood, Texas for the VIII Corps maneuvers from 1 June through 14 June 1941 at Comanche, Texas. The division was then sent to Mansfield, Louisiana from 11 August through 2 October 1941 for the August–September 1941 Louisiana Maneuvers.

The division was transferred to the VIII Corps Louisiana maneuver Area on 27 July 1941, being redesignated as the 2nd Infantry Division in August, and remained there until 22 September 1942, whereupon the formation returned to Fort Sam Houston. They then moved to Camp McCoy at Sparta, Wisconsin on 27 November 1942. Four months of intensive training for winter warfare followed. In September 1943 the division received their staging orders, and moved to the Camp Shanks staging area at Orangeburg, New York on 3 October 1943, where they received Port Call orders. On 8 October the division officially sailed from the New York Port of Embarkation, and started arriving in Belfast, Northern Ireland on 17 October. They then moved over to England, where they trained and staged for forward movement to France.

Narrative
After training in Northern Ireland and Wales from October 1943 to June 1944, the 2nd Infantry Division crossed the channel to land on Omaha Beach on D plus 1 (7 June 1944) near St. Laurent-sur-Mer. Attacking across the Aure River on 10 June, the division liberated Trévières and proceeded to assault and secure Hill 192, a key enemy strong point on the road to Saint-Lô. After three weeks of fortifying the position and by order of Commanding General Walter M. Robertson the order was given to take Hill 192. On 11 July under the command of Col.Ralph Wise Zwicker the 38th Infantry Regiment and with the 9th and the 23rd by his side the battle began at 5:45am. Using an artillery concept from World War I (rolling barrage) and with the support of 25,000 rounds of HE/WP that were fired by 8 artillery battalions, the hill was taken. Except for three days during the Battle of the Bulge, this was the heaviest expenditure of ammunition by the 38th Field Artillery Battalion; And was the only time during the 11 months of combat that 2nd Division Artillery used a rolling barrage. The division went on the defensive until 26 July. After exploiting the Saint-Lo breakout, the 2nd Division then advanced across the (Vire) to take (Tinhebray) on 15 August 1944. The division then raced toward (Brest/France), the heavily defended port fortress which happened to be a major port for German U-Boats. After 39 days of fighting the battle was won, and was the first place the Army Air Forces used bunker busting bombs.

The division took a brief rest 19–26 September before moving to defensive positions at St. Vith, Belgium on 29 September 1944. The division entered Germany on 3 October 1944, and was ordered, on 11 December 1944, to attack and seize the Roer River dams. The German Ardennes offensive in mid-December forced the division to withdraw to defensive positions near Elsenborn Ridge, where the German drive was halted. In February 1945 the division attacked, recapturing lost ground, and seized Gemund, 4 March. Reaching the Rhine 9 March, the 2ID advanced south to take Breisig, 10–11 March, and to guard the Remagen bridge, 12–20 March.



The division crossed the Rhine on 21 March and advanced to Hadamar and Limburg an der Lahn, relieving elements of the 9th Armored Division, 28 March. Advancing rapidly in the wake of the 9th Armored, the 2nd Infantry Division crossed the Weser at Veckerhagen, 6–7 April, captured Göttingen 8 April, established a bridgehead across the Saale, 14 April, seizing Merseburg on 15 April. On 18 April the division took Leipzig, mopped up in the area, and outposted the Mulde River; elements which had crossed the river were withdrawn 24 April. Relieved on the Mulde, the 2nd moved 200 miles, 1–3 May, to positions along the German-Czech border near Schonsee and Waldmünchen, where 2 ID relieved the 97th and 99th ID's. The division crossed over to Czechoslovakia on 4 May 1945, and attacked in the general direction of Pilsen, attacking that city on VE Day. 2nd ID cooperated with Polish Holy Cross Mountains Brigade on these days. The division lost 3,031 killed in action, 12,785 wounded in action, and 457 died of wounds.

2nd Infantry Division returned to the New York Port of Embarkation on 20 July 1945, and arrived at Camp Swift at Bastrop, Texas on 22 July 1945. They started a training schedule to prepare them to participate in the scheduled invasion of Japan, but they were still at Camp Swift on VJ Day. They then moved to the staging area at Camp Stoneman at Pittsburg, California on 28 March 1946, but the move eastward was canceled, and they received orders to move to Fort Lewis at Tacoma, Washington. They arrived at Fort Lewis on 15 April 1946, which became their home station. From their Fort Lewis base, they conducted Arctic, air transportability, amphibious, and maneuver training.

Korean War
With the outbreak of hostilities in Korea during the summer of 1950, the 2nd Infantry Division was quickly alerted for movement to the Far East Command. The division arrived in Korea, via Pusan on 23 July, becoming the first unit to reach Korea directly from the United States. Initially employed piecemeal, the entire division was committed as a unit on 24 August 1950, relieving the 24th Infantry Division at the Naktong River Line. The first big test came when the North Koreans struck in a desperate human wave attack on the night of 31 August. In the 16-day battle that followed, the division's clerks, bandsmen, technical and supply personnel joined in the fight to defend against the attackers.

Shortly thereafter, the 2ID was the first unit to break out of the Pusan Perimeter and they led the Eighth Army drive to the Manchurian Border. The Division was within fifty miles of the Manchurian border when Chinese forces entered the fight. During the Battle of the Ch'ongch'on River, soldiers of the 2nd Infantry Division were given the mission of protecting the rear and right flank of the Eighth Army as it retired to the South. After this battle, while surrounded and outgunned, the division had to fight its way south through what was to become known as "The Gauntlet" - a Chinese roadblock 6 miles long where the 23rd Infantry Regiment fired off its stock of 3,206 artillery shells within 20 minutes, a massive barrage that prevented Chinese troops from following the regiment. This fighting around Kunu-ri cost the division nearly one third of its remaining strength.

The Chinese winter offensive was finally blunted by the 2nd Infantry Division on 31 January at Wonju. Taking up the offensive in a two-prong attack in February 1951, the division repulsed a powerful Chinese counter-offensive in the epic battles of Chipyong-ni and Wonju. The United Nations front was saved and the general offensive continued.

Unfortunately this was not the end of heavy action for the 2nd Infantry Division. In August 1951, it was on the offensive once again, ordered to attack a series of ridges that had been designated threats to the Eighth Army's line. These actions would devolve into the terrible battles that would become Bloody Ridge and Heartbreak Ridge. The Division would not receive relief until October, with its infantry regiments having been heavily gashed. The 23rd Infantry Regiment bore the brunt of the damage, having been severely mauled on Heartbreak Ridge. The 2nd Division was withdrawn after possessing both Bloody and Heartbreak Ridges, and the damage they inflicted upon the Chinese and North Koreans that held the ridges was estimated at 25,000 enemy casualties. Ridge warfare strategy was not embarked upon again as a military strategy for the remainder of the Korean War mainly due to the severe casualties that the 2nd Infantry Division suffered upon Bloody and Heartbreak.

Reorganization
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.

Back to Korea
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 North Korean forces were engaging in increasing border incursions and infiltration attempts and the 2nd Infantry Division was called upon to help halt these attacks. 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. 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 (Joint Security Area) 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).

On June 13, 2002, a 2ID armored vehicle struck and killed two 14-year-old South Korean schoolgirls on the Yangju highway as the vehicle was returning to base in Uijeongbu after training maneuvers. Sergeants Mark Walker and Fernando Nino, the two soldiers involved, were found not guilty of negligent homicide in a subsequent General Court-martial. The deaths and court-martial was the subject of anti-American sentiment in South Korea.

The 2nd Infantry Division is still headquartered in Korea, with a number of camps near the DMZ. Command headquarters are at Camp Red Cloud in Uijeongbu.

Iraq


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.

During the late spring of 2004, many of the soldiers of the 2nd Infantry Division's 2d Brigade Combat Team were given notice that they were about to be ordered to further deployment, with duty in Iraq. Units involved in this call-up included: 1st Battalion, 503rd Infantry Regiment (Air Assault); 1st Battalion, 506th Infantry Regiment (Air Assault); 2d Battalion, 17th Field Artillery Regiment; 1st Battalion, 9th Infantry Regiment (Mechanized); 44th Engineer Battalion; 2nd Forward Support Battalion; Company A, 102nd Military Intelligence Battalion; Company B, 122d Signal Battalion, elements of the 2d Battalion, 72nd Armor Regiment, a team from the 509th Personnel Services Battalion, and B Battery 5th Battalion 5th Air Defense Artillery Regiment (Deployed as a combination of mechanized infantry and light infantry with two platoons of Bradley Fighting Vehicles and 1 platoon of armored HMMWVs). As a result of the short notice, extensive training was conducted by the brigade as they switched from a focus of the foreign defense of South Korea to the offensive operations that were going to be needed in Iraq. Furthermore, time was given for the majority of the soldiers to enjoy ten days of leave. This was vital: many of the soldiers had been in South Korea for a year or more with only two weeks or less time in the United States during their stay of duty. More, they were about to depart on a deployment scheduled to last at least another year. Finally, in August 2004, the brigade deployed to Iraq.

Upon landing in country, the 2d BCT was given strategic command to much of the sparsely populated area south and west of Fallujah. Their mission, however, changed when the major strategic actions began to take place within the city proper. At this time, the brigade combat team was refocused and given control of the eastern half of the volatile city of Ar-Ramadi. Within a few weeks of taking over operational control from the previous units, 2nd Brigade began suffering casualties from violent activity. Many of the units had to move to new camps in support of this new mission. The primary focus of the 2d BCT for much of their deployment was the struggle to gain local support and to minimize casualties.

The brigade was spread out amongst many camps. To the west of the city of Ar-Ramadi sat the camp of Junction City. 2ID units stationed there included: HQ 2d BCT, 2nd ID; 2–17th Field Artillery; 1–9th Infantry; 44th Engineer Battalion; Company A, 102d Military Intelligence Battalion; Company B, 122d Signal Battalion, and Company C (Medical), 2d Forward Support Battalion. To the eastern end of the city sat a much more austere camp, known ironically as the Combat Outpost. This was home to the 1-503d Infantry Regiment. East of them but outside of the city proper itself was the town of Habbiniya and the 1–506th Infantry Regiment. Adjacent to this camp was the logistically important camp of Al-Taqaddum, where the 2d Forward Support Battalion was stationed.

For this mission, the brigade fell under the direct command not of the 2d Infantry Division, but rather under a Marine division. For the first six months while in Ramadi, the BCT fell under the 1st Marine Division. For the second half of the deployment, they were attached to the 2nd Marine Division. While the Marines do not wear unit patches on their uniforms, the units of the 2d BCT involved are authorized to now wear any of the following combat patches: the 2nd Infantry Division patch, the 1st Marine Division unit patch or the 2nd Marine Division unit patch. The 2d Brigade Combat Team was in action in the city of Ramadi for many events, including the Iraqi national elections of January 2005. While the voting was accomplished and little to no violence was seen within the city, few voters participated (estimated to be in the 700 person range for the eastern half of the city, according to 2nd BCT officials).

The 2d BCT also built several new camps within the city. For security reasons, many are left unverified, however ones that can be confirmed include Camps Trotter and Corregidor built to ease the burden on the accommodations at Combat Outpost.

In July 2005, the brigade began to get relieved by units of the Army National Guard, as well as the 3d Infantry Division of the Regular Army. Six months into the deployment, the units of the 2d BCT were given word that they would not be returning to South Korea but, rather, to Fort Carson, Colorado in an effort to restructure the Army and house more soldiers on American soil.

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. 46 soldiers from the brigade were killed during the deployment.

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 Thus the division will be credited with the 17th and 18th Distinguished Service Cross awardings since 1975.

The 2nd Infantry Division's 4th Brigade Combat Team deployed to Iraq in the fall of 2009.

3rd Brigade deployed to Iraq 4 August 2009 for the brigade's third deployment to Iraq, the most of any Stryker Brigade Combat Team (SBCT).

War in Afghanistan
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. 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.

3rd SBCT deployed in December 2011 and served in Afghanistan for one-year. 16 soldiers from the brigade lost their lives during the deployment. They were joined by their sister Stryker brigade, the 2nd SBCT in the spring 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.

Rogue "kill team" criminal charges
During the summer of 2010, the U.S. military charged five members of the 3rd Platoon, Bravo Company, 2nd Battalion, 1st Infantry Regiment with the formation of a "kill team", which staged three separate murders of Afghan civilians in Kandahar province. In addition, seven soldiers were also charged with crimes including hashish use, impeding an investigation and attacking a whistleblowing soldier who alerted MPs during an initially unrelated investigation into hashish use by members of the 3rd Platoon. The alleged ringleader was Staff Sergeant Calvin Gibbs.
 * On 15 January 2010, Gul Mudin was killed "by means of throwing a fragmentary grenade at him and shooting him with a rifle," an action carried out by SPC Jeremy Morlock and PFC Andrew Holmes under the direction of Gibbs. Morlock allegedly told Holmes, age 19 and on his first tour of duty, that the killing was carried out for fun.
 * On 22 February, Gibbs and SPC Michael S. Wagnon allegedly shot the second victim, Marach Agha, and placed a Kalashnikov next to the body to justify the killing.
 * On 2 May, Mullah Adadhdad was killed after being shot and attacked with a grenade. SPC Adam C. Winfield and Gibbs were allegedly the perpetrators.

Christopher Winfield, the father of platoon member SPC Adam Winfield, attempted to alert the Army of the kill team's existence after his son explained the situation from Afghanistan via a Facebook chat. In response to the news from his son, Winfield called the Army inspector general's 24-hour hotline, the office of Sen. Bill Nelson (D-Fla.), and a sergeant at Joint Base Lewis-McChord who told him to call the Army Criminal Investigation Division. He then contacted the Fort Lewis command center and spoke to a sergeant on duty who agreed that SPC Winfield was in potential danger but that he had to report the crime to his superiors before the Army could take action.
