The 1st Infantry Division is a combined arms division of the United States Army, and is the oldest continuously serving division in the Regular Army. [5] It has seen continuous service since its organization in 1917 during World War I. [6] It was officially nicknamed "The Big Red One" (abbreviated "BRO" [2] ) after its shoulder patch [6] and is also nicknamed "The Fighting First." [6] The division has also received troop monikers of "The Big Dead One" and "The Bloody First" as puns on the respective officially sanctioned nicknames. [7] It is currently based at Fort Riley, Kansas.


World War I

The First Expeditionary Division, later designated the 1st Infantry Division, was constituted on 24 May 1917, in the Regular Army, and was organized on 8 June 1917, at Fort Jay, on Governors Island in New York harbor under the command of Brigadier General William L. Sibert, from Army units then in service on the Mexico–United States border and at various Army posts throughout the United States. The original table of organization and equipment (TO&E) included two organic infantry brigades of two infantry regiments each, one engineer battalion; one signal battalion; one trench mortar battery; one field artillery brigade of three field artillery regiments; one air squadron; and a full division train. The total authorized strength of this TO&E was 18,919 officers and enlisted men. George S. Patton, who served as the first headquarters commandant for the American Expeditionary Forces, oversaw much of the arrangements for the movement of the 1st Division to France, and their organization in-country. Frank W. Coe, who later served as Chief of Coast Artillery, was the division's first chief of staff.

The first units sailed from New York City and Hoboken, New Jersey, on 14 June 1917. [8] Throughout the remainder of the year, the rest of the division followed, landing at St. Nazaire, France, and Liverpool, England. After a brief stay in rest camps, the troops in England proceeded to France, landing at Le Havre. The last unit arrived in St. Nazaire 22 December. Upon arrival in France, the division, less its artillery, was assembled in the First (Gondrecourt) training area, and the artillery was at Le Valdahon.

On 4 July, the 2nd Battalion, 16th Infantry, [9] paraded through the streets of Paris to bolster the sagging French spirits. An apocryphal story holds that at Lafayette's tomb, to the delight of the attending Parisians, Captain C.E. Stanton of the division's 16th Infantry Regiment stepped forward and declared, "Lafayette, nous sommes ici! [Lafayette, we are here!]" Two days later, 6 July, Headquarters, First Expeditionary Division was redesignated as Headquarters, First Division, American Expeditionary Forces.

On 8 August 1917, the 1st Division adopted the "square" Table of Organization and Equipment (TO&E), which specified two organic infantry brigades of two infantry regiments each; one engineer regiment; one signal battalion; one machine gun battalion; one field artillery brigade of three field artillery regiments, and a complete division train. The total authorized strength of this new TO&E was 27,120 officers and enlisted men.

On the morning of 23 October, the first American shell of the war was fired toward German lines by a First Division artillery unit. Two days later, the 2nd Battalion of the 16th Infantry suffered the first American casualties of the war.

By April 1918, the German Army had pushed to within 40 miles (64 km) of Paris. In reaction to this thrust, the division moved into the Picardy Sector to bolster the exhausted French First Army. To the division's front lay the small village of Cantigny, situated on the high ground overlooking a forested countryside. The 28th Infantry Regiment [10] attacked the town, and within 45 minutes captured it along with 250 German soldiers. It was the first American victory of the war. The 28th was thereafter named the "Black Lions of Cantigny." [10]

Soissons was taken by the 1st Division in July 1918. The Soissons victory was costly – 700 men were killed or wounded. (One of them, Private Francis Lupo of Cincinnati, was missing in action for 85 years, until his remains were discovered on the former battlefield in 2003). [11] The 1st Division took part in the first offensive by an American army in the war, and helped to clear the Saint-Mihiel salient by fighting continuously from 11 to 13 September 1918. The last major World War I battle was fought in the Meuse-Argonne Forest. The division advanced a total of seven kilometers and defeated, in whole or part, eight German divisions. This victory was mainly due to the efforts of George C. Marshall, who began the war as the division's Deputy Chief of Staff before being elevated to G-3 for the entire AEF in July 1918. Combat operations ended with the implementation of the terms of the Armistice on 11 November 1918. At the time the division was at Sedan, the farthest American penetration of the war, and was the first to cross the Rhine into occupied Germany.

By the end of the war, the division had suffered 4,964 killed in action, 17,201 wounded in action, and 1,056 missing or died of wounds. Five division soldiers received Medals of Honor.

The division's dog-mascot was a mixed breed terrier known as Rags. Rags was adopted by the division in 1918 and remained its mascot until his death in 1936. [12] Rags achieved notoriety and celebrity as a war dog, after saving many lives in the crucial Argonne Campaign by delivering a vital message despite being bombed and gassed.

Interwar period

The 1st Division returned to the continental U.S. in September 1919, demobilized its war-time TO&E at Camp Zachary Taylor at Louisville, Kentucky, and then returned to New York, with its headquarters located at Fort Hamilton in Brooklyn.

On 7 October 1920, the 1st Division organized under the peacetime TO&E, which included two organic infantry brigades of two infantry regiments each, one engineer regiment; one observation squadron; one field artillery brigade of two field artillery regiments; one medical regiment; one division quartermaster train; and a special troops command replacing the remainder of the division train. The total authorized strength of this TO&E was 19,385. 1st Division was one of three infantry divisions and one cavalry division that was authorized to remain at full peacetime strength. It was the only Regular Army division assigned to the Second Corps Area, which also included the 27th Infantry Division of the New York National Guard; the 44th Infantry Division of the New Jersey, New York, and Delaware National Guards; the 21st Cavalry Division of the New York, Pennsylvania, Rhode Island, and New Jersey National Guards; and the 77th, 78th, and 98th Infantry Divisions and the 61st Cavalry Division of the Organized Reserves. This was the organization that existed in the Second Corps Area for the duration of the Interbellum period.

1st Division adopted a new peacetime TO&E in preparation for war on 8 January 1940, which included three infantry regiments, one military police company, one engineer battalion, one signal company, one light field artillery regiment of three field artillery battalions and one medium field artillery regiment of two field artillery battalions, one medical battalion, and one quartermaster battalion. The authorized strength of this TO&E was 9,057 officers and enlisted men. 1st Infantry Division reorganized again on 1 November 1940 to a new TO&E, which added a reconnaissance troop, and organized the two field artillery regiments into a division artillery command, and beefed up the strength to a total authorized strength of 15,245 officers and enlisted men.

Shortly after the German invasion of Poland, beginning World War II in Europe, the 1st Infantry Division, under Major General Walter Short, was moved to Fort Benning, Georgia, on 19 November 1939 where it supported the U.S. Army Infantry School as part of American mobilization preparations. It then moved to the Sabine Parish, Louisiana area on 11 May 1940 to participate in the Louisiana Maneuvers. The division next relocated to Fort Hamilton, Brooklyn on 5 June 1940, where it spent over six months before moving to Fort Devens, Massachusetts, on 4 February 1941. As part of its training that year, the division participated in both Carolina Maneuvers of October and November before returning to Fort Devens, Massachusetts on 6 December 1941.

A day later, on 7 December 1941, the Japanese attacked Pearl Harbor and, four days later, Germany declared war on the United States, thus bringing the United States into the conflict. The division was ordered to Camp Blanding, Florida, as quickly as trains could be gathered and winter weather permitted, and arrived on 21 February 1942. The division, now under Major General Donald C. Cubbison, was there reorganized and refurbished with new equipment, being re-designated as the 1st Infantry Division on 15 May 1942. Within a week, the division was returned to its former post at Fort Benning, Georgia, from where it was expedited on 21 June 1942 to Indiantown Gap Military Reservation for wartime overseas deployment final preparation. The division, now under the command of Major General Terry Allen, a distinguished World War I veteran, departed the New York Port of Embarkation on 1 August 1942, arrived in Beaminster in south-west England about a week later, and departed 22 October 1942 for the combat amphibious assault of North Africa. [14] :75, 622

As part of II Corps, the division landed in Oran, Algeria on 8 November 1942 as part of Operation Torch, the Allied invasion of French North Africa. [15] Elements of the division then took part in combat at Maktar, Tebourba, Medjez el Bab, the Battle of Kasserine Pass (where American forces were pushed back), and Gafsa. It then led the Allied assault in brutal fighting at El Guettar, Béja, and Mateur. The 1st Infantry Division was in combat in the Tunisian Campaign from 21 January 1943 to 9 May 1943, helping secure Tunisia. The campaign ended just days later, with the surrender of almost 250,000 Axis soldiers. After months of nearly continuous fighting, the division had a short rest before training for the next operation.

In July 1943, the division took part in the Allied invasion of Sicily, codenamed Operation Husky, still under the command of Major General Allen. Lieutenant General George S. Patton, commanding the U.S. Seventh Army, specifically requested the division as part of his forces for the invasion of Sicily. It was still assigned to the II Corps. In Sicily the 1st Division saw heavy action when making amphibious landings opposed by Italian and German tanks at the Battle of Gela. The 1st Division then moved up through the center of Sicily, slogging it out through the mountains along with the 45th Infantry Division. In these mountains, the division saw some of the heaviest fighting in the entire Sicilian campaign at the Battle of Troina; some units losing more than half their strength in assaulting the mountain town. On 7 August 1943, Major General Allen was relieved of his command by Lieutenant General Omar Bradley, then commanding the II Corps. Allen was replaced by Major General Clarence R. Huebner who was, like Allen, a decorated veteran of World War I who had served with the 1st Infantry Division throughout the war.

When that campaign was over, the division returned to England, arriving there on 5 November 1943 [14] :622 to prepare for the eventual invasion of Normandy. [6] The 1st Infantry Division and one regimental combat team from the 29th Infantry Division comprised the first wave of troops that assaulted German Army defenses on Omaha Beach on D-Day. [6] [16] The division had to run 300 yards to get to the bluffs, with some of the division's units suffering 30 percent casualties in the first hour of the assault, [17] and secured Formigny and Caumont in the beachhead by the end of the day. The division followed up the Saint-Lô break-through with an attack on Marigny, 27 July 1944.

The division then drove across France in a continuous offensive. It took large numbers of prisoners during the Battle of the Mons Pocket, and reached the German border at Aachen in September. The division laid siege to Aachen, taking the city after a direct assault on 21 October 1944. [6] The 1st Division then attacked east of Aachen through the Hürtgen Forest, driving to the Ruhr, and was moved to a rear area 7 December 1944 for refitting and rest following 6 months of combat. When the German Wacht Am Rhein offensive (commonly called the Battle of the Bulge) was launched on 16 December 1944, [6] the division was quickly moved to the Ardennes front. Fighting continuously from 17 December 1944 to 28 January 1945, the division helped to blunt and reverse the German offensive. Thereupon, the division, now commanded by Major General Clift Andrus, attacked and again breached the Siegfried Line, fought across the Ruhr, 23 February 1945, and drove on to the Rhine, crossing at the Remagen bridgehead, 15–16 March. The division broke out of the bridgehead, took part in the encirclement of the Ruhr Pocket, captured Paderborn, pushed through the Harz Mountains, and was in Czechoslovakia, fighting at Kynšperk nad Ohří, Prameny, and Mnichov (Domažlice District) when the war in Europe ended. Sixteen members of the division were awarded the Medal of Honor during World War II.

Cold War

Korean War

During the Korean War, the Big Red One was assigned to occupation duty in Germany, while acting as a strategic deterrent against Soviet designs on Europe. 1st Infantry Division troops secured the Nuremberg War Crimes Trials and later transported seven convicted Nazi war criminals to Spandau Prison in Berlin.

In 1955, the division colors left Germany and were relocated to Fort Riley, Kansas. [6]


Following its return from Germany, the 1st Infantry Division established headquarters at Fort Riley, Kansas. Its troops reorganized and trained for war at Fort Riley and at other posts. In 1962 and 1963, four 1st Infantry Division Pentomic battle groups (2nd Battle Group, 12th Infantry; 1st Battle Group, 13th Infantry; 1st Battle Group, 28th Infantry; and 2d Battle Group, 26th Infantry) rotated, in turn, to West Berlin, Germany to augment the U.S. Army's Berlin Brigade during an international crisis initiated by construction of the Berlin Wall. These "Long Thrust Operations" were the most significant deployments conducted by 1st Infantry Division troops during the Cold War, placing Big Red One troops in confrontation with hostile communist forces.

From President Kennedy's approval on 25 May 1961, the Army divisions began to convert to the "Reorganization Objective Army Division 1965" (ROAD) structure in early 1962. [19] While the bulk of the division was moved to Fort Riley in April 1970 (the colors returning to Kansas from Vietnam) replacing the inactivated 24th Infantry Division, its 3d Brigade, the Division Forward replacement component of REFORGER for the inactivated 24th Infantry Division, a mixture of cavalry and infantry, was forward-deployed to Germany. The brigade was initially stationed at Sheridan Kaserne, Augsburg, later moving to Cooke Barracks in Göppingen, with four battalions (two infantry, two armor) and the 1st Squadron, 4th Cavalry stationed in Stuttgart/Boeblingen (Panzer Kaserne) and the field artillery battalion in Neu Ulm (Wiley Kaserne) with the 1st Battalion, 26th Infantry in Göppingen and the 3d Battalion, 63d Armor in Augsburg. The Division Forward was inactivated on 15 August 1991 and the Big Red One became a two-brigade division with an assigned National Guard "roundout" brigade.

Vietnam War

The division fought in the Vietnam War from 1965 to 1970. [6] Arriving in July 1965, the division began combat operations within two weeks. By the end of 1965 the division had participated in three major operations: Hump, Bushmaster 1 and Bushmaster II, under the command of MG Jonathan O. Seaman.

In 1966, the division took part in Operation Marauder, Operation Crimp II and Operation Rolling Stone, all in the early part of the year. In March, Major General William E. DePuy took command. [20] In June and July the division took part in the battles of Ap Tau O, Srok Dong and Minh Thanh Road. In November 1966, the division participated in Operation Attleboro.

1967 saw the division in Operation Cedar Falls, Operation Junction City, Operation Manhattan, Operation Billings, and Operation Shenandoah II. MG John H. Hay assumed command in February. On 17 June 1967, during Operation Billings, the division suffered 185 casualties, 35 killed and 150 wounded in the battle of Xom Bo II. [21] Three months later on 17 October 1967, the 1st I.D suffered heavy casualties at the Battle of Ong Thanh with 58 killed.

The division was involved in the Tet Offensive of 1968, securing the massive Tan Son Nhut Air Base. In March, MG Keith L. Ware took command. That same month the division took part in Operation Quyet Thang ("Resolve to Win") and in April the division participated in the largest operation of the Vietnam War, Operation Toan Thang ("Certain Victory"). On 13 September, the division commander, MG Ware, was killed in action when his command helicopter was shot down by enemy anti-aircraft fire. [22] MG Orwin C. Talbott moved up from his position of assistant division commander to assume command of the division.

In the first half of 1969, The Big Red One conducted reconnaissance-in-force and ambush operations, including a multi-divisional operation, Atlas Wedge. The last part of the year saw the division take part in Dong Tien ("Progress Together") operations. These operations were intended to assist South Vietnamese forces to take a more active role in combat. In August, MG A. E. Milloy took command of the 1st I.D. while the division took part in battles along National Highway 13, known as "Thunder Road" to the end of the year.

In January 1970 it was announced that the division would return to Fort Riley. [6] The division officially departed South Vietnam on 7 April 1970, when the division commander Brigadier General John Q. Henion, left Bien Hoa Air Base and returned the colors to Fort Riley. [23] 11 members of the division were awarded the Medal of Honor. During its involvement in the Vietnam war, the division lost 6,146 killed in action, with a further 16,019 wounded. Twenty of its number were taken as prisoners-of-war.

The division participated in REFORGER (Return of Forces in Germany) in all years. REFORGER was the largest set of NATO ground maneuvers since the end of World War II. [24] The group performed surveillance on the border of Czechoslovakia and Germany during the Cold War.

Post-Cold War era

First Gulf War

The division, commanded by Major General Thomas G. Rhame, also participated in Operation Desert Storm. The division's two maneuver brigades from Fort Riley were rounded out by the addition of two tank battalions (2nd and 3rd, 66th Armor), an infantry battalion (1-41st Infantry), and a field artillery battalion (4-3 FA) from 2nd Armored Division (Forward) in Germany. The division played a significant role in the Battle of Norfolk. [25] Specific combat arms and combat support units of the 3rd Battalion, 37th Armor and others were responsible for the initial breach of the Iraqi defenses providing subsequent passages for the rest of VII Corps, consequently rolling over the Iraqi 26th Infantry Division and taking 2,600 prisoners of war. The division continued with the subsequent 260-kilometre (160 mi) long assault on Iraqi-held territory over 100 hours, engaging eleven Iraqi divisions, destroying 550 tanks, 480 armored personnel carriers and taking 11,400 prisoners. 1st Infantry Division Artillery, including 4-3 FA battalion, was decisive during combat operations performing multiple raids and fire missions. These combat operations resulted in the destruction of 50 enemy tanks, 139 APCs, 30 air defense systems, 152 artillery pieces, 27 missile launchers, 108 mortars, and 548 wheeled vehicles, 61 trench lines and bunker positions, 92 dug in and open infantry targets, and 34 logistical sites. [26] By the early morning of 28 February 1991, the division had taken position along the "Highway of Death", preventing any Iraqi retreat. The division's HHC, Alpha, Bravo, Charlie and Delta 3/37 Armor, HHC, Alpha, Bravo, Charlie and Delta 4/37 Armor, and 1st Squadron, 4th Cavalry Regiment (1/4 CAV), was then tasked with securing town of Safwan, Iraq, and the airfield there where the Iraqis were later forced to sign the surrender agreement.

Valorous Unit citation:

For extraordinary heroism during ground combat operations in Operation Desert Storm from 24 February 1991 through 4 March 1991. Organized as Task Force 3/37th Armor, the Unit was composed of HHC, B, and C Companies, 3/37th Armor; A and D Company, Second Battalion, Sixteenth Infantry; First Platoon of B Company and Second Platoon of C Company, Second Battalion, Third Air Defense Artillery; C Company, First Engineer Battalion; and Ground Surveillance Radar Team B, One Hundred and First Military Intelligence Battalion. As part of the First Infantry Division (Mechanized) and VII Corps main effort, Task Forces 3/37th Armor, 2/16th infantry and 4/37th armor breached the Iraqi defense on 24 February 1991, clearing four passage lanes and expanding the gap under direct enemy fire. The task force then attacked 300 kilometres (190 mi) across southern Iraq into northern Kuwait, severing Iraqi lines of communication, and then drove north once again in the middle of the night (with primitive GPS),into Iraq to assist in the seizure of the airfield at the City of Safwan, Iraq the next morning and the securing of that airfield for the Coalition Forces-Iraqi Cease-Fire negotiations or "peace talks". During the operation, over fifty enemy combat vehicles were destroyed and over 1700 prisoners were captured. Throughout the Ground War, the soldiers performed with marked distinction under difficult and hazardous conditions. Their gallantry, determination, and Esprit de Corps guaranteed victory and maintained the finest traditions of the United States Army. [27]

There was also the "bulldozer assault", wherein the 1st and 2nd Brigades from the 1st Infantry Division (Mechanized) used mine plows mounted on tanks and combat earthmovers to bury Iraqi soldiers defending the fortified "Saddam Line." While approximately 2,000 men surrendered, escaping death, one newspaper story reported that U.S. commanders estimated thousands of Iraqi soldiers had been buried alive during the two-day assault over period 24–25 February 1991. [28]

In 1996 the division colors were relocated to the German city of Würzburg (replacing the 3rd Infantry Division, which had relocated to Fort Stewart, GA). The division would remain in Germany until 2006, when the colors were struck and moved (again) to Fort Riley, Kansas.

They were involved in the infamous Battle of Bari Alai, where 3 American soldiers and 2 Latvian soldiers were killed. The battle lasted over the course of 4 days where the fatigued soldiers of Charlie Troop and Hatchet Troop were continuously harassed by Taliban fighters after retaking the observation post. 6-4 Cavalry had the most casualties of the brigade with the exception of the 1st Battalion, 26th Infantry Regiment, who were continuously engaged with the Taliban in the Korengal Valley. CNN branded the brigade "The Dying Duke" because of the brutality and high casualty rate of the unit in their time in theater. Main focuses of the brigade and PRT were to protect population centers such as Jalalabad and Asadabad and help develop the local economy through the construction of roads, and provide security while doing so. The brigade returned to Ft. Hood, Texas in July 2009 after a year of combat in which they recorded over 2000 firefights, over 3000 enemy killed, over 1000 bombs dropped, 26,000 rounds of artillery fire and over 500 Purple Hearts awarded.

They were later joined by 1–5 Field Artillery in northern Iraq in late spring 2011.

2nd Heavy Brigade Combat Team deployed to Baghdad, Iraq in November 2010 in an advise and assist role as part of Operation New Dawn under the command of COL Paul T. Calvert. The brigade HQ was located at Victory Base Complex, where it was co-located within the USD-C Division HQ building and shared the same TOC. This unique C2 relationship earned the brigade the moniker of the "Luckiest Brigade in the Army" from the USD-C commander. The brigade was placed under USD-C (initially 1st AD, then 25th Infantry Division after Dec 2011) and was single-handedly responsible for the entire province of Baghdad.

The Special Troops Battalion, commanded by LTC Shilisa Geter, was located at VBC (Victory Base Complex) and partnered with the Baghdad Police Directorate. Meanwhile, due to the drawdown of US forces and the redeployment of theater-level sustainment brigades, the 299th BSB, commanded by LTC Dale Farrand, assumed the area support mission for all DOD and DOS elements within the province of Baghdad in addition to supporting the Dagger Brigade.

Significant events during this deployment included the resumption of attacks by the Sadrist movement and other Iranian-backed militia, the subsequent operations that stopped those attacks, the rearward passage of lines of USD-North as they redeployed through Baghdad, the organization and training of divisional field artillery regiments for the IA divisions, the fielding of M1 tanks for the 9th IA Division, and the hand-over of all US facilities within Baghdad to the Government of Iraq or elements of the US State Department. During this deployment the brigade simultaneously trained ISF units to the point of conducting Iraqi-led battalion CALFEXs, advised ISF units as they conducted hundreds of Iraqi-led raids which disrupted the attacks of Iranian-backed militia, while also conducting unilateral and combined force protection operations to ensure the security of US bases and redeploying US forces. The brigade experienced nine KIAs during this deployment, the majority of which resulted from a single IRAM attack (improvised rocket-assisted munition) conducted against JSS Loyalty by Iranian-backed militia on 6 June 2011. The brigade departed Iraq in November 2011 after having turned the majority of the city of Baghdad over to complete Iraqi control.

[32] The brigade conducted Operations Tofan I and II. Tofan I's mission was to disrupt insurgent safe havens in the Musa Khel region of Khowst Province, improve the ability for the government to reach the people there and gather intelligence for planning future operations. [33] Tofan II's mission was to establish contact with the insurgents, disrupt their logistics, and reduce any material or moral support from the local population. Movement to the extremely remote area, which featured narrow or non-existent roads set among mountains, included mounted and dismounted soldiers who also had to be aware of the need to control the key terrain features around Suri Kheyl. [34]

Afghanistan 2012–2013

The 1st Infantry Division headquarters deployed to Bagram, Afghanistan on 19 April 2012 as part of Operation Enduring Freedom XIII after receiving responsibility for Regional Command (East)(RC(E)) from 1st Cavalry Division.

During the division's tenure in Afghanistan, the division oversaw a transition of authority to the Afghan National Security Forces (ANSF)201st Corps north of Kabul and had prepared the ANSF 203rd Corps to assume full security responsibility south of Kabul prior to transitioning RC(E) to 101st Airborne Division (AASLT).

The 4th IBCT deployed to Afghanistan in May 2012 for a 9-month deployment. The brigade operated in Ghazni and Paktika provinces in eastern Afghanistan. [36] Dragon Brigade concluded its deployment in February 2013, transitioning oversight of Ghazni province to 1st Brigade, 10th Mountain Division and Paktika province to 2nd Brigade, 10th Mountain Division and full security responsibility for those provinces to 3rd and 2nd Brigades, ANSF 203rd Corps, respectively. [37]

Operation Inherent Resolve

In response to the growing ISIL threat the Department of Defense announced on 25 September 2014 that approximately 500 soldiers from 1st Infantry Division Headquarters will be deployed to Iraq with the task of assisting Iraqi Security Forces. This will be the first Division HQ deployed in Iraq since withdrawal back in 2011. Among the soldiers sent over approximately 200 will be stationed in Baghdad, where they will make up close to half of US troops deployed. [38]

In mid-October 2016 the US Army announced it will deploy about 500 soldiers from the 1st Infantry Division Headquarters to Iraq in the fall of 2016. Troops will assume the role of Combined Joint Forces Land Component Command-Iraq in support of Operation Inherent Resolve. [39]

In late July 2016, the U.S. Army announced that it will send 800 soldiers from 1st Combat Aviation Brigade, 1st Infantry Division, to Afghanistan to support Operation Freedom's Sentinel – the U.S. counter-terrorism operation against the remnants of al-Qaeda, ISIS–K and other terror groups. The brigade will deploy with its AH-64 Apache attack helicopters and UH-60 Black Hawk utility helicopters sometime before October 2016. [40]

Operation Atlantic Resolve

In April 2017, Military.com reported that approximately 4,000 soldiers from the 2nd Armored Brigade Combat Team, 1st Infantry Division will deploy to Europe as part of Operation Atlantic Resolve, replacing the 3rd Armored BCT, 4th Infantry Division in a regular rotation of forces. [41] The unit deployed in September 2017 and redeployed in June 2018, serving throughout Eastern Europe conducting readiness and inter-operability training with NATO Allies to assure U.S. Allies and deter aggression.

The shoulder sleeve insignia (SSI) worn on a unit member's UCP Army Combat Uniform

No credible source states how the insignia of the 1st Infantry Division originated in World War I. There are two theories as to how the idea of the patch came about. The first theory states that the 1st Division supply trucks were manufactured in England. To make sure the 1st Division's trucks were not confused with other allies, the drivers would paint a huge "1" on the side of each truck. Later, the division engineers would go even farther and put a red number one on their sleeves. [42]

The second theory claims that a general of the division decided the unit should have a shoulder insignia. He decided to cut a red numeral "1" from his flannel underwear. When he showed his prototype to his men, one lieutenant said, "the general's underwear is showing!" Offended, the general challenged the young lieutenant to come up with something better. So, the young officer cut a piece of gray cloth from the uniform of a captured soldier, and placed the red "1" on top. [42]



The 1st Infantry Division Band (abbreviated as the 1ID Band and often known as the Big Red One Band) is the musical ambassador for the division that performs for military ceremonies at Fort Riley and the surrounding communities in the Midwest. The 38-member band contains the Concert Wind Ensemble, the Marching Band, a Seated Ceremonial Band as well as other specialized ensembles. [43] The band was notably involved in the Thunder Road incident in Vietnam, during which Major General John Hay ordered the band to march down "Thunder Road", for one mile while playing the Colonel Bogey March. [44] The road, which was critical to the division's operations, was under the control of a North Vietnamese Army regiment. Confused by the action, the regiment withdrew from the area, with the band fulfilling a remarkable combat mission without firing a shot. [45] In 2008, A parachutist injured three members of the band after crashing into them following getting off course during military review. [46]


Toast of the Army,
Favorite Son! Hail to the brave Big Red One!
Always the first to thirst for a fight.
No foe shall challenge our right to victory.
We take the field, A grand sight to see.
Pride of the Infantry.
Soldiers of a great division,
Courage is our tradition,
Forward the Big Red One!

According to the 1st Infantry Division history, the song was composed in 1943 by Captain Donald T. Kellett, who retired after a 30-year career as a colonel and died in 1991. Later revised from "Men of a great division" to "Soldiers of a great division". [47]
