The '''9th Infantry Division''' (nicknamed "Old Reliables") is an inactive infantry division of the [[United States Army]]. It was formed as the 9th Division during [[World War I]], but never deployed overseas. In later years it was an important unit of the U.S. Army during [[World War II]] and the [[Vietnam War]]. It was also activated as a peacetime readiness unit from 1947 to 1962 at [[Fort Dix]], New Jersey as a Training Division, [[West Germany]], and [[Fort Carson]], Colorado as a Full Combat Status Division, and from 1972 to 1991 as an active-duty infantry division at [[Fort Lewis (Washington)|Fort Lewis]], Washington. The division was inactivated in December 1991.

==Insignia==
The [[shoulder sleeve insignia]] is an octofoil resembling a heraldic design given to the ninth son of a family. This represents the son as a circle in the middle with eight brothers around him.<ref>{{cite web|url=http://9thinfdivsociety.org/ |title=9th Infantry Division categories |publisher=9thinfdivsociety.org |date=15 July 1947 |access-date=22 August 2013}}</ref> The blue represents the infantry, the red the artillery, with the white completing the colors of the flag of the United States of America.

==World War I==

The 9th Division was part of a group of six divisions (9th-14th) that the [[United States Department of War|War Department]] directed to be formed in mid-1918 from [[Regular Army (United States)|Regular Army]] troops augmented by [[Selective Service Act of 1917|draftees]]. It was anticipated that the divisions' training would take four months, to be completed by the end of November 1918.<ref>{{cite book |date=1988|title=Order of Battle of the United States Land Forces in the World War |volume=3, Part 2|location=Washington, D.C. |publisher=Center of Military History, United States Army |pages=637}}</ref> 

The 9th Division was organized from July to September 1918 at Camp Sheridan, near [[Montgomery, Alabama]]. At the end of July, the strength of the division was approximately 8,000 officers and men, while during August, draftees sent from [[Camp Hancock (Georgia)|Camp Hancock]], [[Georgia (U.S. state)|Georgia]], [[Fort George G. Meade|Camp Meade]], [[Maryland]], [[Camp Zachary Taylor]] and [[Fort Thomas, Kentucky|Fort Thomas]], [[Kentucky]], [[Camp Upton]] and [[Fort Slocum]], [[New York (state)|New York]], Camp Travis, [[Texas]], and other stations brought the strength to about 22,000. Peak strength was reached during September, with 25,000 officers and men. Systematic training began during August. On 28 October 1918, the division's advance detachment moved to [[Camp Mills]], New York, preparatory to movement overseas. After the signing of the [[Armistice of 11 November 1918|armistice with Germany]], all training was suspended and the advance detachment returned to Camp Sheridan. Demobilization of all emergency period personnel and units except the 45th and 46th Infantry was ordered on 17 January 1919. Demobilization was completed on 15 February 1919.<ref>{{cite book |date=1988|title=Order of Battle of the United States Land Forces in the World War |volume=3, Part 2|location=Washington, D.C. |publisher=Center of Military History, United States Army |pages=642–43}}</ref>

==Interwar period==

The 9th Division was reconstituted on 24 March 1923, allotted to the First [[Corps Area]] for mobilization responsibility, and assigned to the [[I Corps (United States)|I Corps]]. [[Fort Devens|Camp Devens]], [[Massachusetts]], was designated as the mobilization and training station for the division upon reactivation. The 18th Infantry Brigade and additional active and inactive elements were assigned to the division on 24 March 1923. The division's inactive units were assigned to active associate units for mobilization purposes. During the period 1923–39, the 9th Division was represented in the active Army by the 18th Infantry Brigade and other assorted divisional elements that formed the base force from which the remainder of the division would be reactivated in the event of war. The division headquarters was organized on 28 July 1926 as a Regular Army Inactive (RAI) unit with [[United States Army Reserve|Organized Reserve]] personnel at the [[South Boston Army Base|Army Base]], [[Boston, Massachusetts]]. In 1926-27, the active associate concept was abandoned and many of the division's inactive elements were organized as RAI units by mid-1927 in the First and Second Corps Areas. The active elements of the division maintained habitual training relationships with divisional RAI units, as well as those of the I Corps, [[XI Corps (United States)|XI Corps]], and the [[76th Infantry Division (United States)|76th]], [[94th Infantry Division (United States)|94th]], and [[97th Infantry Division (United States)|97th Divisions]]. The RAI and Reserve units often trained with the active elements of the division during summer training camps usually conducted at Camp Devens and [[Fort McKinley (Maine)|Fort McKinley]], [[Maine]]. 

The 18th Infantry Brigade's [[5th Infantry Regiment (United States)|5th]] and [[13th Infantry Regiment (United States)|13th Infantry Regiment]]s additionally supported the Reserve units' conduct of the [[Citizens Military Training Camp]]s also held at Camp Devens and Fort McKinley. When funds were available, the 18th Infantry Brigade and the division's other active elements, which included the 9th Tank Company, 9th Ordnance Company, 9th Quartermaster Regiment, and [[25th Field Artillery Regiment (United States)|25th Field Artillery Regiment]], held maneuvers and command post exercises at Camp Devens, during which the division headquarters was occasionally formed in a provisional status. The division headquarters was also provisionally formed in 1939 for the First Army maneuvers in upstate New York. Under the new "triangular" tables of organization, the 9th Division was reactivated, less Reserve personnel, on 1 August 1940 at [[Fort Bragg]], [[North Carolina]], and assigned to the I Corps. Between August and November, the division was increased to a strength of 6,000, and to 8,000 men by January 1941. During January, around 4,500 selectees also arrived, chiefly coming from Camp Upton and Fort Dix. Over the next three months, a further 2,000 were assigned, chiefly from Fort Devens and Fort Dix, allowing the division to reach its war strength of 14,000. The division participated in the Carolina Maneuvers from September–November 1941.{{sfn|Clay|2010a|p=217-218}}

=== Combat chronicle ===
The 9th Infantry Division was among the first U.S. combat units to engage in offensive ground operations during World War II. (The others were the [[32nd Infantry Division (United States)|32nd]] and the [[41st Infantry Division (United States)|41st]] in the Pacific on [[New Guinea campaign|New Guinea]], [[Evans Carlson#Carlson's Raiders|Carlson's Raiders]] on [[Makin Island raid|Makin Island]], the [[1st Marine Division (United States)|1st Marine]], and the
[[23rd Infantry Division (United States)|Americal]] on [[Guadalcanal campaign|Guadalcanal]], and, alongside the 9th in [[Operation Torch|North Africa]], were the [[1st Infantry Division (United States)|1st Infantry]], [[3rd Infantry Division (United States)|3rd Infantry]], [[34th Infantry Division (United States) |34th Infantry]] and the [[2nd Armored Division (United States)|2nd Armored]] Divisions.) The 9th saw its first combat on 8 November 1942, when its elements landed at [[Algiers]], [[Safi, Morocco|Safi]], and [[Port Lyautey]], with the taking of Safi by the 3rd Battalion of the 47th Infantry Regiment standing as the first liberation of a city from Axis control in World War II.

With the collapse of French resistance on 11 November 1942, the division patrolled the Spanish Moroccan border. The 9th returned to Tunisia in February and engaged in small defensive actions and patrol activity. On 28 March 1943 it launched an attack in southern Tunisia and fought its way north into [[Bizerte]], 7 May. In August, the&nbsp;9th landed at [[Palermo]], [[Sicily]], and took part in the capture of [[Randazzo]] and [[Messina]].

Sent to England for further training, the division landed on [[Utah Beach]] on 10 June 1944 ([[D-day]] plus 4), cut off the [[Cotentin Peninsula]], drove on to [[Cherbourg Harbour]] and penetrated the port's heavy defenses.

Following a brief rest in July, the division took part in the [[Saint-Lô|St. Lo]] break-through and in August helped close the [[Falaise pocket|Falaise Gap]]. Turning east, the 9th crossed the [[Marne River|Marne]], 28 August, swept through [[Saarlautern]],<ref>{{cite video |year=1944 |title=Video: American Sub Rescues Airmen (1944) |url=https://archive.org/details/gov.archives.arc.39150 |publisher=[[Universal Newsreel]] |access-date=21 February 2012}}</ref> and in November and December held defensive positions from [[Monschau]] to [[Hellenthal|Losheim]].

Moving north to [[Eschweiler|Bergrath]], Germany, it launched an attack toward the [[Roer]] river, 10 December, taking [[Düren|Echtz and Schlich]]. From mid-December through January 1945, the division held defensive positions from [[Monschau|Kalterherberg]] to [[Bütgenbach|Elsenborn]]. On 30 January the division jumped off from Monschau in a drive across the Roer and to the [[Rhine]], crossing at [[Remagen]], 7 March.

After breaking out of the Remagen bridgehead, the 9th assisted in the sealing and clearing of the [[Ruhr Pocket]], then moved 150&nbsp;miles&nbsp;(240&nbsp;km) east to [[Nordhausen, Thuringia|Nordhausen]], where it assisted in the liberation of the [[Mittelbau-Dora concentration camp]], and attacked in the [[Harz Mountains]], 14–20 April. On 21 April the Division relieved the [[U.S. 3rd Armored Division|3d Armored Division]] along the [[Mulde River]], near [[Dessau]], and held that line until [[VE-day]].

After the war, the Division moved south to Ingolstadt. The Division assumed control of the Dachau Concentration Camp in early July.

== Vietnam War ==
The 9th Division was reactivated on 1 February 1966, and arrived in [[South Vietnam]] on 16 December 1966 from [[Fort Riley]], Kansas. On deployment the division was assigned to the [[III Corps (South Vietnam)|III Corps]] Tactical Zone of Vietnam where it commenced operations in [[Tiền Giang Province|Dinh Tuong]] and [[Long An Province]]s (6 January-31 May 1967) in [[Operation Palm Beach]]. Its area of operations was in the rivers and canals of the [[Mekong Delta]] from 1967 to 1972. Operating deep within the [[Viet Cong]] (VC)–controlled Delta, the Division was charged with protecting the area and its population against VC insurgents and ensuring the success of the South Vietnamese government's pacification program. Faced with unrelenting physical hardships, a tenacious enemy and the region's rugged terrain, the Division established strategies and quantifiable goals for completing their mission.<ref>Hunt Jr, Ira [https://muse.jhu.edu/book/633 "The 9th Infantry Division In Vietnam"] 2010.

From 1967 on, the 2d Brigade of the division was the Army contingent of the [[Mobile Riverine Force]] (MRF). This brigade lived on the ships of Navy Task Force 117, and were transported on their infantry missions throughout the Mekong Delta on [[Armored Troop Carrier (LCM)|Tango boats]] (converted [[landing craft]]) supported by various other armored boats. The MRF was often anchored near the South Vietnamese city of [[Mỹ Tho]], or near the Division's [[Đồng Tâm Base Camp]] and they conducted operations in coordination with the Navy SEAL teams, the South Vietnamese Marines, units of the ARVN [[7th Division (South Vietnam)|7th Division]] and River Assault Groups. Following the [[Tet Offensive]] in 1968, General Westmoreland stated that the Division and the MRF saved the Delta region from falling to the [[People's Army of Vietnam]] forces. In 1969, the division also operated throughout [[IV Corps (South Vietnam)|IV Corps]].<ref>{{cite web |url=https://warontherocks.com/2018/01/tet-navy/ |title=Defending the Mekong Delta: Tet and the Legacy of the Brown-Water Navy |first=John Darrell | last=Sherwood |date=31 January 2018 |website=War on the Rocks |access-date=16 March 2019 }}</ref><ref>{{cite book|author=William B.

=== 9th Infantry Division (Motorized) ===
[[File:US Navy 020413-N-5362A-013 U.S. Navy SEALs (SEa, Air, Land) operate Desert Patrol Vehicles (DPV) while preparing for an upcoming mission.jpg|thumb|left|U.S. [[Navy SEAL]]s operate Desert Patrol Vehicles (DPV), the successor to the Fast Attack Vehicle pioneered by the 9th ID (Motorized).]]

In 1980, the United States "recognized the military's inability to project forces swiftly to trouble-spots in the world with the capability of defeating armored forces of the Soviet Union or its surrogates." This inability was especially highlighted for the SE Asia and Middle East areas. In response, the army set about creating a new formation that would be set apart from the pending "Infantry Division 86" design. The formation would need to be highly mobile on a tactical and strategic level. From 1983, the division served as the High-Technology Test-Bed (HTTB) for the army to pursue this concept. The division was given the leeway to experiment, design, and finalize the design of the needed formstion. Initially described as a high technology light Division, the term eventually settled upon and to highlight the highly mobile nature was motorized division.{{sfn|"Motorized Experience of the 9th Infantry Division"|page=2663-4}} The motorized infantry division was to be equipped with enhanced technology to give it deployability and fire power and fill the gap between light and heavy divisions. The idea was to create a lighter version of the armored and mechanized divisions, which could be deployed easily by aircraft, while providing more firepower than a light infantry division.<ref name="McGrath">{{cite book |last1=McGrath |first1=John J. |title=The Brigade: A History, Its Organization and Employment in the US Army |date=2004 |publisher=Combat Studies Institute Press |location=Fort Leavenworth, Kansas |url=https://www.armyupress.army.mil/Portals/7/combat-studies-institute/csi-books/Brigade-AHistory.pdf |archive-url=https://web.archive.org/web/20180216085009/http://www.armyupress.army.mil/Portals/7/combat-studies-institute/csi-books/Brigade-AHistory.pdf |url-status=dead |archive-date=16 February 2018 |access-date=11 June 2020}}</ref>

Initially the vision was to create three motorized brigades with three new types of infantry battalion:<ref name="Excellence">{{cite web |last1=Romjue |first1=John L. |title=The Army of Excellence |url=https://history.army.mil/html/books/069/69-4-1/cmhPub_69-4-1.pdf |archive-url=https://web.archive.org/web/20150921142305/http://www.history.army.mil/html/books/069/69-4-1/cmhPub_69-4-1.pdf |url-status=dead |archive-date=21 September 2015 |publisher=US Army Center of Military History |access-date=21 June 2020}}</ref><ref name="Corps">{{cite web |title=Fort Lewis and Yakima Firing Center: Environmental Impact Statement |year = 1983|url=https://books.google.com/books?id=EfI3AQAAMAAJ |publisher=US Army Corps of Engineers |access-date=21 June 2020}}</ref>
* Light Attack Battalion
* Combined Arms Battalion Light
* Combined Arms Battalion Heavy

The light attack battalions utilized the Fast Attack Vehicles (FAV - later re-designated the [[Desert Patrol Vehicle]]), essentially a [[Volkswagen]]-engined dune buggy with either a 40 mm [[Mk 19 grenade launcher]] or 12.7 mm [[M2 Browning machine gun]]. The FAV was designed to provide highly mobile firepower that could attack the flanks of heavier mechanized units. Some variants also mounted [[BGM-71 TOW|TOW missiles]]. All of these weapons systems were attached to the FAV by a mount designed to break away if the vehicle rolled over, which they were prone to do. The FAVs were problematic at best and were eventually replaced by various versions of the [[Humvee]]/HMMWV light truck.<ref name=the-mighty-buggies>{{cite web |last1=Trevithick|first1=Joe |title=The U.S. Army had a whole battalion of armed dune buggies |url=http://www.wearethemighty.com/articles/the-u-s-army-had-a-whole-battalion-of-armed-dune-buggies |publisher=War is Boring |access-date=23 August 2016 |date=22 August 2016 |via=We are The Mighty.com}}</ref><ref name="Excellence"/><ref name="Corps"/>

The combined arms battalions were organized as a mix of assault gun companies and light motorized infantry companies, with the heavy battalions fielding two assault gun companies and one light motorized infantry company, while the ratio was reversed in the light battalions. The assault gun companies were to be equipped with the [[Armored Gun System]] (AGS), but because of delays in the AGS program they were initially equipped with M901 ITVs Improved Tow Vehicles, then [[M551 Sheridan]] [[light tank]]s and later with Humvees with TOW missiles or Mk 19 grenade launchers. Light motorized infantry companies were equipped with Humvees mounting a Mk 19 grenade launcher. Each combined arms battalion also fielded a combat support company equipped with mortars, scouts, and an anti-armor platoon slated to be equipped with Humvees mounting a ground version of the [[AGM-114 Hellfire|Hellfire]] missile. As this Hellfire version never entered service, the platoons were later also equipped with Humvees with TOW missiles.<ref name="McGrath"/><ref name="Excellence"/><ref name="Corps"/>

The division's first and third brigade were to field one of each of the three new battalions, while the second brigade would field three combined arms battalions heavy. The third brigade was to field one light and one heavy combined arms battalion and the 9th Cavalry Brigade two attack helicopter battalions, one combat support aviation battalion, and one cavalry reconnaissance squadron. The division artillery would consist of three battalions equipped with [[M198 howitzer|M198 155&nbsp;mm towed howitzers]], one light artillery rocket battalion with [[M102 howitzer|M102 105&nbsp;mm towed howitzers]] and [[M270 Multiple Launch Rocket System]]s, and one target acquisition battery. The division support command would field three forward support, one cavalry support and one main support battalion. However, because of the delay of the Armored Gun System the division did only activate four of the envisioned five combined arms battalions heavy and retained the 2nd Battalion, 77th Armor instead.

Parts of the division were organized at the end of the 1980s as follows:

In case of war with [[Warsaw Pact]] forces the division would have reinforced the [[Allied Forces Baltic Approaches]] Command defending Denmark. By 1984 the 9th Cavalry Brigade (Air Attack) was testing motorcycles for reconnaissance work in its reconnaissance squadron, the 3rd Squadron, [[5th Cavalry Regiment (United States)|5th Cavalry Regiment]].<ref>Marr and Kingsley, [https://static.dvidshub.net/media/pubs/pdf_34076.pdf New Roles for Combat Motorcycles], [[Armor Magazine]], September–October 1984, 33-36.</ref> And the 9th Infantry Division (MTZ) tested motorized infantry doctrine at the Yakima Firing Center in Eastern Washington, at the [[National Training Center]] at [[Fort Irwin]] California and in Korea during the annual [[Team Spirit]] exercise. While the motorized units performed well, they were vulnerable to heavier mechanized forces, particularly if forced to stand and fight. They were also extremely vulnerable to indirect artillery fire.{{sfn|"Motorized Experience of the 9th Infantry Division"|page=236}} 

On 1 April 1984, Echo Company of the 15th Engineer Battalion reorganized to form the 73rd Engineer Company (Assault Ribbon Bridge), which was assigned to I Corps, which in turn attached it as separate company to the 15th Engineer Battalion. With the switch from [[Combat Arms Regimental System]] to the [[United States Army Regimental System]] the division saw a few of its units reflagged or inactivated:

== Inactivation ==
The division was the first to undergo full inactivation following the end of the [[Cold War]]. Army leadership at first decided that inactivating units would turn in all of their equipment at "10/20" standard, i.e. in ready and reusable condition. The division struggled to meet this standard, which required both extensive work by the division's soldiers and high costs for repair parts. While the remaining 9th ID soldiers were ultimately successful, later inactivating units were not required to attain this goal.{{sfn|"Motorized Experience of the 9th Infantry Division"|pages=41, 53}}

The inactivation of the division began on 28 September 1990 with the inactivation of the 1st Brigade, 2nd Battalion, 23rd Infantry,<ref name="2-23 Infantry">{{cite web |title=2nd Battalion, 23rd Infantry - Lineage and Honors |url=https://history.army.mil/html/forcestruc/lineages/branches/inf/0023in002bn.htm |archive-url=https://web.archive.org/web/20080324112002/http://www.history.army.mil/html/forcestruc/lineages/branches/inf/0023in002bn.htm |url-status=dead |archive-date=24 March 2008 |publisher=US Army Center of Military History |access-date=21 June 2020}}</ref> and 4th Battalion, 23rd Infantry.<ref name="4-23 Infantry">{{cite web |title=4th Battalion, 23rd Infantry - Lineage and Honors |url=https://history.army.mil/html/forcestruc/lineages/branches/inf/0023in004bn.htm |archive-url=https://web.archive.org/web/20080324112007/http://www.history.army.mil/html/forcestruc/lineages/branches/inf/0023in004bn.htm |url-status=dead |archive-date=24 March 2008 |publisher=US Army Center of Military History |access-date=21 June 2020}}</ref> The 1st Battalion, 84th Field Artillery inactivated on 15 January 1991.

The division was identified as the second-highest priority inactive division in the [[United States Army Center of Military History]]'s lineage scheme due to its numerous accolades and long history. All of the division's flags and heraldic items were moved to the [[National Infantry Museum]] at [[Fort Benning]], Georgia following its inactivation.{{sfn|McKenney|1997|p=21}} Should the U.S. Army decide to activate more divisions in the future, the center stated its activation recommendations would be the 9th Infantry Division, then the [[24th Infantry Division (United States)|24th Infantry Division]], the [[5th Infantry Division (United States)|5th Infantry Division]], and the [[2nd Armored Division (United States)|2nd Armored Division]].{{sfn|McKenney|1997|p=22}} The [[7th Infantry Division (United States)|7th Infantry Division]], previously inactivated, resumed service as an administrative headquarters at [[Joint Base Lewis–McChord]] in 2012.
