The 84th Training Command ("Railsplitters"[1]) is a formation of the United States Army. During World War I it was designated the 84th Division, American Expeditionary Forces; during World War II it was known as the 84th Infantry Division. From 1946 to 1952, the division was a part of the United States Army Reserve as the 84th Airborne Division. In 1959, the division was reorganized and redesignated once more as the 84th Division. The division was headquartered in Milwaukee in command of over 4,100 soldiers divided into eight brigades—including an ROTC brigade—spread throughout seven states.

Changes to the U.S. Army Reserve organizations from 2005 until 2007 redesigned the unit as the 84th Training Command (Leader Readiness) and it was paired with the Army Reserve Readiness Training Center (ARRTC). The flag resided at Fort McCoy, Wisconsin. As a result of Base Realignment and Closure (BRAC) throughout the Army, the ARRTC was moved to Fort Knox, Kentucky. The 84th Training Command (LR) underwent a command-directed move to Fort Knox, Kentucky in advance of the ARRTC in September 2008. Since the move, the 84th Training Command and ARRTC split, leaving the ARRTC with leader readiness and training support. The 84th Training Command was re-designated once again to 84th Training Command (Unit Readiness).

In September 2010, the 84th was renamed 84th Training Command and began reorganization. The 84th mission currently supports three numbered and three named training divisions – The 78th Training Division (Ft. Dix, NJ), the 86th Training Division (Ft. McCoy, WI), and the 91st Training Division (Ft. Hunter Liggett, CA), Atlantic Training Division (Ft. Dix, NJ), Great Lakes Training Division (Arlington Heights, IL), Pacific Training Division (Camp Parks, Dublin, CA)

Tradition has it that the division traces its lineage to the Illinois militia company in which a young Captain Abraham Lincoln served during the Black Hawk War of 1832.[citation needed] The division patch was selected to honor this legacy and the division's origin in Illinois. For this reason, the alternative nickname of "Lincoln County" Division" has been used to denote the 84th.

World War I[edit]

The 84th Division trained at Camp Zachary Taylor during World War I. Troops from Indiana and Kentucky made up this division.

The division was activated in September 1917 at Camp Taylor, Kentucky. It was initially made up of enlisted draftees from Indiana and Kentucky (who chose the formation's distinctive patch and nickname, an allusion to Abraham Lincoln who grew up in those two states), with a cadre of Regular Army, Officers Reserve Corps, and National Army officers. Later groups of enlisted men assigned to the division to replace men transferred to other units came from Ohio, North Dakota, and Montana. The division remained in training at Camp Taylor until August 1918. It was deployed to France in October 1918 to serve as a training formation for replacements which would be sent to the Western Front. At the war's end, the formation was recalled home and, without having seen combat actions, inactivated in January 1919.

Its commanders included Brig. Gen. Wilber E. Wilder (25 August 1917), Maj. Gen. Harry C. Hale (6 October 1917), Brig. Gen. Wilber E. Wilder (26 November 1917), Brig. Gen. Wilber E. Wilder (15 December 1917), Maj. Gen. Harry C. Hale (1 March 1918), Maj. Gen. Harry C. Hale (5 June 1918), Maj. Gen. Harry C. Hale (21 July 1918), Brig. Gen. Wilber E. Wilder (18 October 1918), Maj. Gen. Harry C. Hale (31 October 1918).

Interwar period[edit]

The division was reconstituted in the Organized Reserve on 24 June 1921 and assigned to the state of Indiana. The headquarters was organized on 6 September 1921.

World War II[edit]

The 84th Infantry Division was ordered into active military service on 15 October 1942, at Camp Howze, Texas, about 60 miles north of Dallas. Then, it was composed of the 333rd, 334th and 335th Inf. Regts.; 325th, 326th, 327th and 909th FA Bns.; 309th Engr. Combat Bn.; 309th Med, Bn.; 84th Sig. Co.; 784th Ord. Light Maintenance Co.; 84th QM Co.; 84th Recon Troop. It embarked on 20 September 1944 and arrived in the United Kingdom on 1 October, for additional training. The division landed on Omaha Beach, 1–4 November 1944, and moved to the vicinity of Gulpen, the Netherlands, 5–12 November.

The division entered combat on 18 November with an attack on Geilenkirchen, Germany, (Operation Clipper) as part of the larger offensive in the Roer Valley, north of Aachen. Operating under the command of Lt-Gen Brian Horrocks the division was supported by British tanks of the Sherwood Rangers Yeomanry, specialist armoured units of 79th Armoured Division, and XXX Corps' artillery.[2][3][4] Taking Geilenkirchen on 19 November, the division pushed forward to take Beeck (Geilenkirchen) and Lindern (Geilenkirchen) in the face of heavy enemy resistance, 29 November.[5] After a short rest, the division returned to the fight, taking Wurm and Würm (Geilenkirchen), Mullendorf, 18 December, before moving to Belgium to help stem the German winter offensive (Battle of the Bulge).

On a break from the Potsdam Conference, President Harry S. Truman strides along inspecting a line of G.I.'s of the 84th Infantry Division at Weinheim (50 miles S of Frankfurt, Germany), July 26, 1945. Stood behind him is the division's commander, Major General Alexander R. Bolling.

Battling in snow, sleet, and rain, the division threw off German attacks, recaptured Verdenne, 24–28 December, took Beffe and Devantave (Rendeux), 4–6 January 1945, and seized La Roche, 11 January. By 16 January, the Bulge had been reduced. After a 5-day respite, the 84th resumed the offensive, taking Gouvy and Beho. On 7 February, the division assumed responsibility for the Roer River zone, between Linnich and Himmerich (near Heinsberg), and trained for the river crossing.

On 23 February 1945, the first day of Operation Grenade, the division cut across the Roer, took Boisheim and Dülken, 1 March, crossed the Niers on 2 March, took Krefeld, 3 March, and reached the Rhine by 5 March. One day before, the 'Krefeld-Uerdinger Brücke' was blown off by Wehrmacht soldiers.[6] The division trained along the west bank of the river in March.

After crossing the Rhine, 1 April, the division drove from Lembeck toward Bielefeld in conjunction with the 5th Armored Division, crossing the Weser River to capture Hanover, 10 April. By 13 April, it had reached the Elbe, and halted its advance, patrolling along the river. Soviet troops were contacted at Balow, 2 May 1945. The division remained on occupation duty in Germany after VE-day, returning to the United States on 19 January 1946 for demobilization. It was redesignated a reserve formation on 21 January 1946.

Troops of the 84th Infantry Division liberated two satellite camps of the Neuengamme Concentration Camp: Ahlem (a.k.a. Hannover-Ahlem), on 10 April 1945, and Salzwedel, on 14 April 1945. As such, the 84th is officially recognized as a "Liberating Unit" by both the U.S. Army's Center of Military History and the Holocaust Memorial Museum.[7]


The 84th returned to the US in January 1946 and was inactivated at Camp Kilmer, New Jersey on January 21, 1946

Cold War to present[edit]

Following the conclusion of World War II, the division was made part of the Army Reserve. In January 1946, it was redesignated the 84th Airborne Division and headquartered out of Wisconsin. In 1947, it was designated as the Army's Airborne Reserve Command. Five years later, in 1952, the division was reorganized again, this time as a training division composed of three regiments—the 274th, 334th, and 339th. Throughout the 1950s, the division would continue its conversion to a training formation, changing its subordinate unit makeup from regiments to brigades and support groups.

On 24 January 1991, elements of the 84th Division (Training) were activated and mobilized for support roles in Operation Desert Storm. Less than three months later, on 22 March 1991, the elements were returned home. In 1993, reorganization within the Army Reserve brought about the merger between the 84th and the 85th Division (Training). The move expanded the 84th Division's area of command to include the rest of Wisconsin and Illinois, as well as all of Missouri and Iowa. Soon after, in June 1994, units from the 84th participated in peacekeeping operations as part of the multinational observer force in the Sinai, Egypt, and remained there until July 1995.

In April 1995, the formation was once more redesignated, this time as an institutional training division. This change brought with it command of units and training in the state of Nebraska. In August 1995, army reorganization further expanded the 84th's range of authority to command the fourteen U.S. Army Reserve Forces Schools in Region E—Wisconsin, Michigan, Minnesota, Illinois, Indiana, and Ohio.

In October 2004, the 84th Division (Institutional Training) underwent a major transformation. All eight brigades realigned under the 100th Division and the Headquarters and Division Band combined with the Army Reserve Readiness Training Center (ARRTC) located at Fort McCoy, Wis., to create the 84th U.S. Army Reserve Readiness Training Command (84th USARRTC). The expertise and resources from the two units gave the 84th USARRTC an edge on the type and amount of training opportunities offered. The three Army Reserve NCO academies were also realigned under the new 84th USARRTC.

In October 2006, the 84th USARRTC underwent another major transformation as 12 brigades from the Army Reserve's Institutional Training Divisions realigned under the command. The brigades were responsible for Officer Education System (OES) training, such as the Combined Arms Exercise (CAX) and Intermediate Level Education (ILE), and Senior Reserve Officer Training Corps (SROTC) support to universities across the country.

In February 2007, the 84th USARRTC was renamed the 84th Training Command (Leader Readiness) in response to the unit's transformation under the Army Reserve's Decision Point 74. The 84th Training Command had exercise command and control over three professional development brigades, one schools brigade, one training development brigade, the 84th Division Band, and eventually the Small Arms Readiness Group.

In September 2008, the 84th Training Command relocated from Milwaukee, Wisconsin and Fort McCoy, Wisconsin to Fort Knox, Kentucky.

In October 2009, the focus of the 84th Training Command shifted from leader readiness to unit readiness. The Army Reserve Readiness Training Center and the three U.S. Army Reserve NCO Academies moved from the umbrella of the 84th and became the 83rd USARRTC which reported directly to the U.S. Army Reserve Command.

In October 2010, the 84th Training Command reorganized to align with the transformation of the Army Reserve. The 84th Training Command is the executing agent of the U.S. Army Reserve's Combat Support Training Programs which includes Warrior Exercises (WAREX), Combat Support Training Exercises (CSTX). The 84th Training Command provides multiple collective training opportunities which prepare units for operational deployments worldwide.
