The1st Cavalry Division ("First Team")[1] is acombined armsdivision and is one of the most decorated combat divisions of theUnited States Army.[3] It is based atFort Hood,Texas.[4] It was formed in 1921 and served duringWorld War II, theKorean War, theVietnam War, thePersian Gulf War, with theStabilization Force inBosnia and Herzegovina, theIraq War, theWar in Afghanistan as well asOperation Freedom's Sentinel andOperation Inherent Resolve. As of July 2023, the 1st Cavalry Division is subordinate to theIII Armored Corps and is commanded byMajor General Thomas M. Feltey.[citation needed]
The unit is unique in that it has served as acavalry division, aninfantry division, anair assault division and anarmored division during its existence.[citation needed]
The history of the 1st Cavalry Division began in 1921, after the Army established a permanent cavalry divisiontable of organization and equipment on 4 April 1921. It authorized asquare division organization of 7,463 officers and men, organized as follows:[5]
On 20 August 1921, theWar Department constituted the 1st and2nd Cavalry Divisions in theRegular Army to meet partial mobilization requirements, authorizing the establishment of the 1st Cavalry Division under the newTO&E on 31 August 1921. Since the 1st Cavalry Division was to be organized from existing units, the division headquarters was activated on 13 September 1921, even though all of the division's subordinate units did not arrive until 1922.[citation needed]
The 1st Cavalry Division was allotted to the EighthCorps Area and assigned to theThird Army. The division headquarters and 2nd Cavalry Brigade were located atFort Bliss, Texas, while the 1st Cavalry Brigade was stationed atCamp Harry J. Jones inDouglas, Arizona. The headquarters facilities used by the 1st Cavalry Division were those previously vacated by the 8th Brigade when it was commanded by MGJohn J. Pershing in 1916, and the wartime15th Cavalry Division, which had existed at Fort Bliss between 10 December 1917 and 12 May 1918.[citation needed]
The 1st, 7th, and8th Cavalry Regiments had previously been assigned to the wartime15th Cavalry Division until they were returned to the Eighth Corps Area troop list on 12 May 1918. The 1st Cavalry Regiment remained assigned until it was transferred to the 1st Cavalry Division on 20 August 1921. The 7th, 8th, and 10th Cavalry Regiments were transferred on 13 September 1921, although the assignment of the10th Cavalry Regiment to the 1st Cavalry Division was controversial because the transfer violated theJim Crow laws.[citation needed] This controversy continued until 18 December 1922, when the 5th Cavalry Regiment, then on the VIII Corps Area Troop List, swapped places with the 10th Cavalry Regiment.[citation needed]
In 1923, the 1st Cavalry Division held division maneuvers for the first time, intending to hold them annually thereafter. However, financial constraints made that impossible. Only in 1927, through the generosity of a few ranchers who provided free land, was the division able to conduct such exercises again. In 1928 Major GeneralHerbert B. Crosby, Chief of Cavalry, faced with personnel cuts, reorganized the cavalry regiments, which in turn reduced the size of the 1st Cavalry Division. Crosby's goal was to decrease overhead while maintaining or increasing firepower in the regiments. After the reorganization, each cavalry regiment consisted of a headquarters and headquarters troop, a machine gun troop, a medical and chaplain element, and two squadrons, each with a headquarters element and two line troops. The cavalry brigades' machine gun squadrons were inactivated, while the responsibility for training and employing machine guns fell to the regimental commanders, as in the infantry.[citation needed]
At about the same time, Crosby cut the cavalry regiment, and the army staff, seeking to increase the usefulness of the wartime cavalry division, published new tables of organization for an even larger unit. The new structure increased the size of the signal troop (177), expanded the medical unit to a squadron (233), and endorsed Crosby's movement of the machine gun units from the brigades to the regiments (2x176). A divisional aviation section, anarmored car squadron (278), and a tank company (155) were added, thefield artillery battalion was expanded to a regiment (1,717), and divisional strength rose to 9,595.[citation needed]
With the arrival of the 1930s, serious work started on the testing and refining of new equipment and TO&Es for a mechanized and motorized army. To facilitate this, the 1st Cavalry Division traded the 1st Cavalry Regiment, which was in the process of being reorganized as a separate mechanized unit, for the 12th Cavalry Regiment from the 2nd Cavalry Division on 3 January 1933.[6] Taking into account recommendations from the VIII Corps Area, theArmy War College, and theCommand and General Staff School, the board developed a new smaller triangular cavalry division, which the 1st Cavalry Division evaluated during maneuvers atToyahvale, Texas, in 1938. Like the 1937 infantry division test, the maneuvers concentrated on the divisional cavalry regiments around which all other units were to be organized.
Following the test, a board of 1st Cavalry Division officers, headed byBrigadier GeneralKenyon A. Joyce, rejected the three-regiment division and recommended retention of the two-brigade (four-regiment) organization. The latter configuration allowed the division to deploy easily in two columns, which was accepted as standardcavalry tactics. However, the board advocated reorganizing the cavalry regiment along triangular lines, which would give it a headquarters and headquarters troop, a machine gun squadron with special weapons and machine gun troops, and three rifle squadrons, each with one machine gun and three rifle troops. No significant change was made in the field artillery, but the test showed that the engineering element should remain a squadron to provide the divisional elements greater mobility on the battlefield and that the special troops idea should be extended to include the division headquarters, signal, and ordnance troops; quartermaster, medical, engineer, reconnaissance, and observation squadrons; and a chemical warfare detachment. One headquarters would assume responsibility for the administration and disciplinary control of these forces.[citation needed]
Although the study did not lead to a general reorganization of the cavalry division, the wartime cavalry regiment was restructured, effective 1 December 1938, to consist of a headquarters and headquarters troop, machine gun and special weapons troops, and three squadrons of three rifle troops each. The special troops remained as structured in 1928, and no observation squadron or chemical detachment found a place in the division. With the paper changes in the cavalry divisions and other minor adjustments, the strength of a wartime divisional rose to 10,680.[citation needed]
In order to prepare for war service, 1st Cavalry Division participated in the following maneuvers:
The division was composed of the following units:[7]
With theattack on Pearl Harbor on 7 December 1941, the "great laboratory" phase for developing and testing organizations, about which Marshall wrote in the summer of 1941, closed, but the War Department still had not developed ideal infantry, cavalry, armored, and motorized divisions. In 1942 it again revised the divisions based on experiences gained during the great GHQ maneuvers of the previous year. As in the past, the reorganizations ranged from minor adjustments to wholesale changes.[citation needed]
1st Cavalry Division retained its square configuration after the 1941 maneuvers, but with modifications. The division lost its antitank troop, the brigades their weapons troops, and the regiments their machine gun and special weapons troops. These changes brought no decrease in divisional firepower, but placed most weapons within the cavalry troops. The number of .50-caliber machine guns was increased almost threefold. In the reconnaissance squadron, the motorcycle and armored car troops were eliminated, leaving the squadron with one support troop and three reconnaissance troops equipped with light tanks. These changes increased the division from 11,676 to 12,112 officers and enlisted men.[citation needed]
The last of the 1st Cavalry Division's mounted units permanently retired their horses and converted to infantry formations on 28 February 1943. However, a mounted special ceremonial unit known as the Horse Platoon – later, the Horse Cavalry Detachment – was established within the division in January 1972. Its ongoing purpose is to represent the traditions and heritage of the American horse cavalry at military ceremonies and public events.[8]

Although originally part of the III Corps (which eventually participated in theEuropean Theater), while training in the United States, most of the 1st Cavalry Division arrived in Australia as shown above, continued its training atStrathpine,Queensland, until 26 July, then moved toNew Guinea to stage for the Admiralties campaign 22–27 February 1944. The division experienced its first combat in theAdmiralty Islands, units landing atLos Negros on 29 February 1944.Momote airstrip was secured against great odds. Attacks by theJapanese were thrown back, and the enemy force surrounded by the end of March. Nearby islands were taken in April and May. The division next took part in the invasion ofLeyte, on 20 October 1944, capturedTacloban and the adjacent airstrip, advanced along the north coast, and secured Leyte Valley, with elements landing on and securingSamar Island. Moving down Ormoc Valley (in Leyte) and across the Ormoc plain, the division reached the west coast of Leyte on 1 January 1945.[citation needed]
The division then invadedLuzon, landing in theLingayen Gulf area on 27 January 1945, and fought its way as a "flying column" toManila by 3 February 1945. More than 3,000 civilian prisoners at theUniversity of Santo Tomas, including more than 60 US Army nurses (some of the "Angels of Bataan andCorregidor") were liberated,[9] and the 1st Cavalry then advanced east of Manila by the middle of February before the city was cleared. On 20 February the division was assigned the mission of seizing and securing crossings over theMarikina River and securing theTagaytay-Antipolo Line. After being relieved on 12 March in the Antipolo area during the middle of theBattle of Wawa Dam, elements pushed south intoBatangas and provinces of theBicol Region together with recognized guerrillas. They mopped up the remaining pockets of resistance in these areas in small unit actions. Resistance was officially declared at an end on 1 July 1945.[citation needed]
The division left Luzon on 25 August 1945 foroccupation duty in Japan, arriving inYokohama on 2 September 1945 and enteringTokyo on 8 September, the first United States division to enter the Japanese capital. 101 unit was set up in May 1945 to search for the missing soldiers in the Second World War. The detachment consisted of two officers (Captain MacColeman andLieutenant Foley) and 15 enlisted members. The operation was successful, although it lasted three years. Occupation duty in Japan followed for the next five years.
On 25 June 1950,North KoreaattackedSouth Korea, and the 1st Cavalry Division was rushed toKorea to help shore up thePusan Perimeter,landing onPohang On 18 July 1950.[citation needed]
After theX Corps attack atIncheon, abreakout operation was launched at the Pusan Perimeter. The division then joined theUN counteroffensive that recaptured most of South Korea by the end of September. The UN offensive was continued northwards, pastSeoul, and across the38th Parallelinto North Korea on 1 October. The momentum of the attack was maintained, and the race to the North Korean capital,Pyongyang, ended on 19 October when elements of the division and theRepublic of Korea Army (ROK)1st Infantry Divisioncaptured the city. The advance continued, but against unexpectedly stiffening resistance. TheChinesePeople's Volunteer Army (PVA) entered the war on the side of North Korea, making theirfirst attacks in late October.[citation needed]
On 28 October 1950,Eighth Army commander GeneralWalton Walker relieved the 1st Cavalry Division of its security mission in Pyongyang. The division's new orders were to pass through the ROK 1st Division's lines atUnsan and attack toward theYalu River. Leading the way on the twenty-ninth, the 8th Cavalry Regiment departed Pyongyang and reached Yongsan-dong that evening. The 5th Cavalry Regiment arrived the next morning, with the mission to protect the 8th Cavalry Regiment's rear. With the arrival of the 8th Cavalry Regiment at Unsan on the 31st, the ROK 1st Division redeployed to positions northeast, east, and southeast of Unsan; the 8th Cavalry took up positions north, west, and south of the town. Meanwhile, the ROK 15th Regiment was desperately trying to hold its position east of the 8th Cavalry, across the Samt'an River.[citation needed]
During the afternoon of 1 November, thePVA attack north of Unsan gained strength against the ROK 15th Regiment and gradually extended to the right flank of the 1st Battalion, 8th Cavalry. At nightfall, the 1st Battalion controlled the northern approaches to the Samt'an River, except for portions of the ROK 15th Regiment's zone on the east side. The battalion's position on the left was weak; there were not enough soldiers to extend the defensive line to the main ridge leading into Unsan. This left a gap between the 1st and 2nd Battalions. East of the Samt'an the ROK 15th Regiment was under heavy attack, and shortly after midnight it no longer existed as a combat force. At 19:30 on 1 November, the PVA116th Division attacked the 1st Battalion, 8th Cavalry, all along its line. At 21:00 PVA troops found the weak link in the ridgeline and began moving through it and down the ridge behind the 2nd Battalion, penetrating its right flank and encircling its left. Now both the 1st and 2nd Battalions were engaged by the enemy on several sides. Around midnight, the 8th Cavalry received orders to withdraw southward to Ipsok. At 01:30 on 2 November, no PVA activity was reported in the 3rd Battalion's sector south of Unsan. But as the 8th Cavalry withdrew, all three battalions became trapped by roadblocks made by the PVA 347th Regiment, 116th Division south of Unsan during the early morning hours. Members of the 1st Battalion who were able to escape reached the Ipsok area. A head count showed the battalion had lost about 15 officers and 250 enlisted men. Members of the 2nd Battalion, for the most part, scattered into the hills. Many of them reached the ROK lines near Ipsok. Others met up with the 3rd Battalion, the hardest hit. Around 03:00 the PVA launched a surprise attack on the battalion command post. Hand-to-hand fighting ensued for about half an hour before the PVA was driven from the area. The disorganized members of the 3rd Battalion formed a core of resistance around three tanks on the valley floor and held off the PVA until daylight. By that time, only six officers and 200 enlisted men were still able to function. More than 170 were wounded, and the number of dead or missing were uncounted. Attempts by the 5th Cavalry to relieve the beleaguered battalion were unsuccessful, and the 3rd Battalion, 8th Cavalry, soon ceased to exist as an organized force.[11]
Following the battle, there were disparaging rumors about the 1st Cavalry Division's fighting abilities, including a folk song of the time called "The Bug-Out Ballad".[12] The series of engagements that were rumored to have given rise to the song were due (at least partly) to the myth that the division lost itsunit colors.[13] Other Army and Marine units disparagingly described the division shoulder insignia as representing 'The horse they never rode, the river they never crossed, and the yellow speaks for itself'. Another version goes: "The shield they never carried, the horse they never rode, the bridge they never crossed, the line they never held, and the yellow is the reason why."
The 1st Cavalry Division remained in the line until it was relieved by the45th Infantry Division from theOklahoma Army National Guard in January 1952. Following the relief, the division returned to Japan. The division returned to Korea in 1957, where it remained until 1965.
As a result of theHowze Board, helicopters were used inVietnam for reconnaissance, command and control, troop transport, attack gunships, aerial rocket artillery, medical evacuation, and supply.[14] It was a revolution in maneuver doctrine that freed the infantry from the limitations of terrain to attack the enemy at the time and place of its choosing.
The11th Airborne Division had been reactivated atFort Benning on 1 February 1963 and redesignated as the11th Air Assault Division (Test). In September 1963, Air Assault I exercises tested the Airmobility concept at the battalion level at Fort Stewart inGeorgia. Air Assault II, a much larger exercise, was conducted across two states in October 1964. The 11th Air Assault Division operated against the82nd Airborne Division and the 11th thoroughly dominated the exercise.[15]
When the test proved successful, the assets of the 11th Air Assault Division (Test), the 10th Air Transport Brigade, and the2nd Infantry Division were merged into a single unit. The colors and subordinate unit designations of the 1st Cavalry Division were transferred from its post in Korea. On 3 July 1965, the colors of the 11th Air Assault Division (Test) were cased and retired and the 1st Air Cavalry Division colors were moved onto the field at Doughboy Stadium and passed to the commander of the former 11th Air Assault Division, Major General Kinnard.[16] At the same time, the personnel and units of the 1st Cavalry Division that remained in Korea were reflagged as a new 2nd Infantry Division. On 29 July 1965, PresidentLyndon B. Johnson ordered the 1st Air Cavalry Division toVietnam.[17]: 30 [15][18][19]

Shortly thereafter, the division began deploying toCamp Radcliff,An Khe, Vietnam, in theCentral Highlands and was equipped with the newM16 rifle, theUH-1 troop carrier helicopter, UH-1C gunships, theCH-47 Chinook cargo helicopter, and the massiveCH-54 Skycrane cargo helicopter.[20] All aircraft carried insignia to indicate their battalion and company.[21]
The division's first major operation was to help relieve theSiege of Plei Me nearPleiku and the pursuit of the withdrawingPeople's Army of Vietnam (PAVN) which culminated in theBattle of Ia Drang, described in the bookWe Were Soldiers Once...And Young, was also the basis of the filmWe Were Soldiers. Because of that battle the division earned thePresidential Unit Citation (US), the first unit to receive such in the war. In 1966, the division attempted to root the communistViet Cong (VC) and PAVN out ofBình Định Province withOperation Masher,Operation Crazy Horse andOperation Thayer. 1967 was then spent conductingOperation Pershing, a large scale search and destroy operation of PAVN/VC base areas inII Corps in which 5,400 PAVN/VC soldiers were killed and 2,000 captured. InOperation Jeb Stuart, January 1968, the division moved north toCamp Evans, north ofHue and on to Landing Zones Sharon and Betty, south ofQuang Tri City, all in theI Corps Tactical Zone.[22]
In the early morning hours of 31 January 1968, the largest battle of the Vietnam War, theTet Offensive, was launched by 84,000 PAVN/VC soldiers acrossSouth Vietnam. In the division's area of operation, the PAVN/VC forcesseized most of the city of Huế. As the 3rd Brigade, 1st Cavalry Division, fought to cut off PAVN/VC reinforcements pouring intoHuế, atQuảng Trị, five battalions, most from the324th Division, attacked the city and LZ Betty (Headquarters 1st Brigade). To stop allied troops from intervening, three other PAVN/VC infantry battalions deployed as blocking forces, all supported by a 122mm-rocket battalion and two heavy-weapons companies armed with 82mm mortars and 75mm recoilless rifles. After intense fighting, 900 PAVN/VC soldiers were killed in and around Quảng Trị and LZ Betty. However, across South Vietnam, 1,000 Americans, 2,100 South Vietnamese, 14,000 civilians, and 32,000 PAVN/VC were killed.[22]
In March 1968 the division shifted forces toLZ Stud, the staging area forOperation Pegasus to break the siege of the Marine'sKhe Sanh Combat Base—the second largest battle of the war. All three brigades participated in this airmobile operation, along with a Marine armor thrust. US Air ForceB-52s alone dropped more than 75,000 tons of bombs on PAVN soldiers from the304th and325th Divisions encroaching the combat base in trenches. As these two elite enemy divisions, with history atDien Bien Phu and theIa Drang Valley, depleted, the division leapfrogged west, clearingRoute 9, until at 0:800 hours 8 April, the 2nd Battalion, 7th Cavalry, linked-up with Marines at the combat base, ending the 77-day siege.[22][23]
On 19 April 1968, as the 2nd Brigade continued pushing west to theLaotian border, the 1st and 3rd Brigades (about 11,000 men and 300 helicopters) swung southwest and air assaultedA Shau Valley, commencingOperation Delaware. The PAVN was a well-trained, equipped, and led force. They turned A Shau into a formidable sanctuary —complete withPT-76 tanks; powerful crew-served 37mm antiaircraft cannons, some radar controlled; twin-barreled 23mm cannons; and scores of 12.7mm heavy machine guns. Along-range penetration operation was launched by members of the Division'slong-range reconnaissance patrol (LRP) against the PAVN when they seized"Signal Hill"—the name attributed to the peak ofDong Re Lao Mountain, a densely forested 4,879 feet (1,487 m) mountain midway in the valley—so the 1st and 3rd Brigades, slugging it out hidden deep behind the mountains, could communicate with Camp Evans near the coast or with approaching aircraft.[24][25]
Despite hundreds of B-52 and jet air strikes, the PAVN forces shot down aC-130, aCH-54, twoCH-47s and nearly two dozen UH-1s. Many more were lost in accidents or damaged by ground fire. The division also suffered more than 100 dead and 530 wounded in the operation. Bad weather aggravated the loss by causing delays in troop movements, allowing a substantial number of PAVN to escape to safety in Laos. Still, the PAVN lost more than 800 dead, a tank, 70 trucks, two bulldozers, 30 flamethrowers, thousands of rifles and machine guns, and dozens of antiaircraft cannons. They also lost tons of ammunition, explosives, medical supplies and foodstuffs.[24]
In mid-May 1968 Operation Delaware ended, however, the division continued tactical operations in I Corps as well as local pacification and "medcap" (medical outreach programs to local Vietnamese). In the autumn of 1968, the division relocated south toPhước Vĩnh Base Camp northeast ofSaigon, at theIII Corps Tactical Zone.[22] In May 1970, the division participated in theCambodian Incursion, withdrawing from Cambodia on 29 June. Thereafter, the division took a defensive posture while US troops withdrawals continued from Vietnam. On 29 April 1971 the bulk of the division was withdrawn to Fort Hood, Texas, but its 3rd Brigade remained as one of the final two major US ground combat units in Vietnam, departing 29 June 1972. However, its 1st Battalion,7th Cavalry, Task Force Garry Owen, remained another two months.[26]
In the Vietnam War, the division suffered more casualties than any other U.S. Army division: 5,444 men killed in action and 26,592 wounded in action.[22][27][28]
When the 1st Cavalry Division (Airmobile) departed Vietnam, its colors were retained by reflagging the existing1st Armored Division at Fort Hood as the "new" 1st Cavalry Division, configured as an armored division. Concurrently, the colors of the 1st Armored Division were transferred to Germany where the4th Armored Division was reflagged as the 1st Armored Division.
In the aftermath of Vietnam, the 1st Cavalry Division was converted from an airmobile light infantry role into a triple capabilities (TRICAP) division. The unit received an infusion of mechanized infantry and artillery, to make it capable of missions needing three types of troops;armored, airmobility and air cavalry.[29]
In the post-Vietnam era, morale in the US Army waned. In response, the Department of the Army released a morale–enhancing order in 1973 permitting local commanders to encourage morale-enhancing uniform distinctions. Consequently, many units embraced the wear of various military berets.[31][32][33][34] The 1st Cavalry Division's use of various colored berets started in 1971 with the TRICAP experiment: black for armor, light–blue forinfantry, red forartillery, andkelly–green for support.[29][34] The division eventually settled on the use of black berets for all 1st Cavalry soldiers and continued wearing them until the Army's morale enhancing order ended in 1979.[29][34][32][33]
However, the TRICAP concept was short-lived, and by 1975, the division was reorganized under the Round-Out Division concept, with two active duty armored brigades and one National Guard armored brigade - theMississippi Army National Guard's155th Armored Brigade from 1984 to 1991.[35]
The division participated in numerousREFORGER exercises, and was used to test new doctrinal concepts and equipment, including theXM-1 tank. The unit assignment and structure changed significantly, notably when 1st Battalion,9th Cavalry was inactivated. The 13th Signal Battalion fielded mobile subscriber equipment (MSE), a secure digital communications system for corps and below units.

1st Cavalry Division, Fort Hood (Texas)[36] (Operation Reforger unit.POMCUS materiel depots inBelgium (Grobbendonk,Zutendaal) and theNetherlands (Brunssum,Eygelshoven) and ammunition depot in Zutendaal)[37]By October 1986 all heavy army and national guard divisions, including the 1st Cavalry Division, had transitioned to theArmy of Excellence J-seriesTOE.[59] Thus the division's tank battalions fielded 58M1A1 Abramsmain battle tanks, 6M3 Bradley cavalry fighting vehicles and 6M106A2 mortar carriers.[60] The two tank battalions of the 155th Armored Brigade were also equipped with M1A1 Abrams tanks.[61] The division's and 155th brigade's mechanized battalions fielded 54M2 Bradleyinfantry fighting vehicles, 12M901 ITV anti-tank vehicles, 6 M3 Bradley cavalry fighting vehicles, 6 M106A2 mortar carriers.[62][63][64]
The authorized strength for an armored J-Series division was 17,027 men,[65] 348 M1A1 Abramsmain battle tanks, 316 cavalry/infantry fighting vehicles, 72M109 155 mmself-propelled howitzers, 9M270 Multiple Launch Rocket Systems, 12M110 203 mm self-propelled howitzers (transferred in 1986 to field artillery brigades at corps level),[66][41] 50 to 44 attack helicopters (50 for an allAH-1S Cobra combat aviation brigade, 44 for an all AH-64 Apache combat aviation brigade), 38 to 28 utility helicopters (38 if the Assault Aviation Company was equipped with UH-1H helicopters, 28 if the Assault Aviation Company was equipped withUH-60A Black Hawk helicopters; in the first case 2 were assigned to the aviation intermediate maintenance company as reserve), and 54OH-58 Kiowa observation helicopters (4 assigned to divisional Aviation Office).[67] The divisional air defense artillery battalion was to be equipped with 18 MIM-72 Chaparral and 36M247 Sergeant York (DIVAD) systems,[67] but with the cancelation of the York air defense battalions retained a mix ofMIM-72 Chaparral,M163 Vulcan andFIM-92 Stinger systems, until theAN/TWQ-1 Avenger could be fielded, with the 1st Cavalry Division's 4th Battalion, 5th Air Defense Artillery receiving the first systems in 1989.[53]
The 1st Cavalry next fought as a heavy division, duringOperation Desert Storm[68] in January and February 1991. It participated in theBattle of Norfolk. The 1st Cavalry Division deployed in October 1990 as part ofXVIII Corps. The division's 'round-out' formation, the 155th Armored Brigade was not deployed. It was planned to augment the division by attaching the Tiger Brigade from the2nd Armored Division, but that brigade was attached to the1st Marine Expeditionary Force (1st &2nd Marine Divisions) to add heavy armor support to that force. Consequently, the 1st Cavalry Division was assigned the role ofCENTCOM's reserve. During the Ground war, was assigned toVII Corps and was crucial in the movement of ground forces to the Kuwaiti and west Saudi Arabian theaters by making two assaults into Iraqi held territory with the division's Black Jack Brigade moving north drawing Iraqi divisions out ofKuwait to support the Iraqi units defending inIraq. This movement was led by the 1st Battalion, 5th Cavalry, from theWadi Al-Batin to just north ofBasra through several Iraqi divisions before stopping. The assault byM1 Abrams main battle tanks,M2 Bradleyinfantry fighting vehicles, and other support vehicles moved much faster than was thought possible, catching the Iraqi Army off guard.
The 13th Signal Battalion was the first unit in the U.S. Army to deploy mobile subscriber equipment (MSE) into combat.[citation needed] Installing, operating, and maintaining communications equipment to support a communications network spanning over 280 kilometers, the 13th Signal Battalion again provided the division's communications. The 13th Signal Battalion was the first unit in the U.S. Army to provide digital communications inWest Asia. It was a gateway link from the Port of Dammam to the U.S. Army XVIII Airborne Corps Headquarters.
After the division returned from Kuwait, the 1st "Tiger" Brigade, 2nd Armored Division was reflagged as the 3rd Brigade, 1st Cavalry Division (separate lineage).[69] In response to the continued hostile movements by theIraqi Armed Forces after Desert Storm, theU.S. Department of Defense ordered successive Operation Intrinsic Action deployments by combat brigades and special forces units to the Iraq/Kuwait border. The 1st Cavalry's three brigades contributed heavily to the decade-long deployments from 1992 to 2002.[citation needed]
The 1st Cavalry Division took control of the U.S.peacekeeping contingent inBosnia-Herzegovina with approximately 6,900 personnel on 20 June 1998, as part of the multinationalStabilization Force (SFOR). The 1st Brigade served for RotationSFOR 4. 2nd Brigade served for Rotation SFOR 5. The 2nd Brigade was alerted for action during theRussian move from Bosnia to thePristina International Airport in June 1999, but no action was ultimately taken after consultation at the highest levels inNATO. In August 1999, the10th Mountain Division took over operations in theTuzla/Multinational Division North area.
Elements of the division arrived inWashington, D.C., shortly after the11 September attacks.
In October 2001 an advance party of a division brigade combat team was deployed to theIraq/Kuwait border. Some divisional units participated in the initial2003 invasion of Iraq.[70] The division in its entirety deployed to Iraq in January 2004, sending an initial detachment of the 9th Cavalry Regiment into combat in September 2003. The 1st Cavalry relieved the 1st Armored Division inBaghdad. Among its subordinate formations were:Louisiana's256th Infantry Brigade; Arkansas'39th Infantry Brigade; element of A Company, 28th Signal Battalion; elements of Washington's81st Armored Brigade; and the 2d Battalion, 162nd Infantry (Oregon Army National Guard), and Company E (Air Traffic Control Services), 126th Aviation, MA ARNG. After spending more than a year in Iraq, it redeployed back to the US by April 2005. It was relieved by the3rd Infantry Division. Division Artillery (DIVARTY) was organized as the 5th BCT. It contained HHB, DIVARTY; 1–7 CAV; 1–8 CAV; 1–21 FA; and the 515th FSB (Provisional). The division fought in many key battles against insurgents, including theSecond Battle of Fallujah in 2004, where the 2nd Brigade Combat Team engaged in house-to-house intenseurban combat to root out enemy cells in the city. During its OIF2 deployment, the division assigned and attached personnel numbered approximately 40,000. 168 personnel were killed in action, with approximately 1,500 wounded.
The division assumed duties as Headquarters,Multi-National Division – Baghdad from November 2006 to December 2007. 4th Brigade Combat Team, activated in 2005, arrived inNinawa Governorate in October and November 2006. However, 2–12 Cavalry was detached, deployed to Baghdad to augment the division efforts there.
The 3d Brigade Combat Team, "Greywolf", deployed to theDiyala Province in September 2006 and fought in theBattle of Baqubah as a part of theIraq War troop surge of 2007.
The division assumed duties as the Headquarters, Multi-National Division – Baghdad Jan 2009– Jan 2010. The deployment was extended by 23 days past the one year mark.
The 4th Brigade Combat Team "Long Knife" deployed toMosul,Nineva Province, October 2006 to January 2008 and again September 2010 to September 2011.
In November 2001, elements of the 1st Cavalry Division (3d Platoon, 545th MP CO, originally assigned to 2d Brigade "BlackJack" 1st Cav) deployed toBagram Airfield,Afghanistan as part ofOperation Enduring Freedom – Afghanistan.
In May 2011, the division headquarters deployed in support ofOperation Enduring Freedom and assumed command ofRegional Command East, replacing the101st Airborne Division (Air Assault). The 1st Infantry Division HQ took command of RC-East on 19 April 2012.
In June 2014, the division headquarters returned to Afghanistan and assumed command ofRegional Command South, replacing the4th Infantry Division.
In October 2014, the division flag returned to Fort Hood, leaving its Deputy Commanding General behind as the new Train Advise Assist Command South.
Operation Enduring Freedom – Afghanistan (OEF-A) ended in late 2014.[71]
After the completion of Operation Enduring Freedom – Afghanistan, the new US deployment to Afghanistan was known asOperation Freedom's Sentinel.[71]
In June 2015, the division element in TAAC South was relieved by an element from the7th Infantry Division Headquarters.
In September 2016, the 1st Cavalry Division Headquarters deployed again to Afghanistan, this time with the 1st Cavalry Division Sustainment Brigade alongside it.[72][73] The headquarters served as the United States Forces – Afghanistan National Support Element, and was also responsible for Bagram Airfield, the largest US military base in Afghanistan. It supported forces serving in the United States'Operation Freedom's Sentinel and NATO'sResolute Support Mission, enabling both the international effort to train, advise, and assist the Afghan National Defense and Security Forces and the counterterrorism fight. The 1st Cavalry Division Sustainment Brigade also supported both Operation Freedom's Sentinel and Resolute Support and was the Army's only deployed active dutySustainment Brigade until US forces withdrew in 2021.
The division's 3d BCT deployed in February 2017 to Kuwait, and elements of 3ABCT supported operations in Iraq to retake Mosul from ISIS.

Theshoulder sleeve insignia was originally approved 3 January 1921, with several variations in colors of the bend and horse's head to reflect the subordinate elements of the division. The design was authorized for wear by all subordinate elements of the division on 11 December 1934, and previous authorization for the variations was canceled. The insignia is worn subdued on field uniforms after experience in the Vietnam War, where the gold was too conspicuous. Normally, the gold is changed to the base color of the uniform to subdue it.[87] With the retirement of the green "Class A" uniform in October 2015, only the subdued version of the SSI is worn, on the ACU's left sleeve.
It consists on a yellow, triangularNormanshield with rounded corners 5.25 inches (133 mm) in height overall, a black diagonal stripe extends over the shield from upper left to lower right, and in the upper right a black horse's head cuts off diagonally at the neck, all within a 0.125-in green border.
Yellow was chosen because it is the traditional cavalry color, and the horse's head refer to the division's original cavalry structure. Black, symbolic of iron, alludes to the transition to tanks and armor. The black diagonal stripe represents a swordbaldric and is a mark of military honor; it also implies movement "up the field" and thus symbolizes aggressive elan and attack. The one diagonalbend and the one horse's head also allude to the division's numerical designation.
Description: A metal and enameled device, 1 inch in height overall, consisting of a gold-colored Normanshield with a black horse's headcouped in sinisterchief, and a black bendcharged with two five-pointed stars. Properly: Or, on a bend sable two stars of five points Or, in chief sinister a sable couped horse head, a border vert
Symbolism: The device is a miniature reproduction of the 1st Cavalry Division's shoulder sleeve insignia with the addition of two five-pointed stars. The Division Commander and the Division Staff wore the distinctive insignia design from 1922 to 1934 as a shoulder sleeve insignia.
Background: The distinctive unit insignia was approved 25 August 1965.
The flag of the 1st Cavalry Division is a white field with the distinctive yellow triangular Norman shield with rounded corners, a black diagonal stripe extending over the shield from upper left to lower right and in the upper right a silhouetted horse's head cut off diagonally at the neck with a green border.[88]
