84th Training Command

and Kentucky made up this division. The division was activated in September 1917 at Camp Zachary 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, including Laurence Halstead as chief of staff. 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).

The 84th Division headquarters arrived at the Port of Hoboken, New Jersey, aboard the USS Wilhelmina on 19 January 1919 after four months of overseas service and was demobilized on 26 July 1919 at Camp Zachary Taylor, Kentucky. It was reconstituted in the Organized Reserve on 24 June 1921, allotted to the Fifth Corps Area, and assigned to the XV Corps. The division was further allotted to Indiana as its home area. The division headquarters was organized on 6 September 1921 at room 408 in the Federal Building in Indianapolis. The headquarters was relocated in August 1922 to 24 East Michigan Street and moved again in 1928 to the Meridian Life Building. The headquarters was moved twice more before World War II: first to the Chamber of Commerce Building in 1933; and finally back to the Federal Building in 1937. It remained there until activated for World War II. Though the designated mobilization and training station for the division was Camp Knox, Kentucky, and some of the division's training occurred there, much of the training activities for the division headquarters and its subordinate units transpired in other locations as well. For example, the headquarters occasionally trained with the staff of the 10th Infantry Brigade, 5th Division, at Fort Benjamin Harrison, Indiana. The infantry regiments of the division held their summer training primarily with the units of the 10th Infantry Brigade at Fort Thomas, Kentucky, or Fort Benjamin Harrison, but some years they went to Camp Knox. For some years, the 167th and 168th Infantry Brigades and their subordinate units conducted camp at the Culver Military Academy in Culver, Indiana. Other units, such as the special troops, artillery, engineers, aviation, medical, and quartermaster trained at various posts in the Fifth Corps Area, usually with similar active units of the 5th Division. For example, the division's artillery trained with the 5th Division artillery units stationed at Camp Knox; the 309th Engineer Regiment usually trained at Fort Benjamin Harrison; the 309th Medical Regiment trained at Camp Knox; and the 309th Observation Squadron trained with the 88th Observation Squadron at Wright Field, Ohio. In addition to the unit training camps, the infantry regiments of the division rotated responsibility for conducting the infantry Citizens Military Training Camps held at Fort Thomas and Camp Knox each year. On a number of occasions, the division participated in various Fifth Corps Area or Second Army command post exercises in conjunction with other Regular Army, National Guard, and Organized Reserve units. Unlike the Regular and Guard units in the First Corps Area, the 84th Division did not participate in the Fifth Corps Area maneuvers and the Second Army maneuvers of 1936, 1940, and 1941 as an organized unit due to lack of enlisted personnel and equipment. Instead, the officers and a few enlisted reservists were assigned to Regular and Guard units to fill vacant slots and bring the units up to war strength for the exercises. Additionally, some were assigned duties as umpires or as support personnel. ==World War II==

Before Organized Reserve infantry divisions were ordered into active military service, they were reorganized on paper as "triangular" divisions under the 1940 tables of organization. The headquarters companies of the two infantry brigades were consolidated into the division's cavalry reconnaissance troop, and one infantry regiment was removed by inactivation. The field artillery brigade headquarters and headquarters battery became the headquarters and headquarters battery of the division artillery. Its three field artillery regiments were reorganized into four battalions; one battalion was taken from each of the two 75 mm gun regiments to form two 105 mm howitzer battalions, the brigade's ammunition train was reorganized as the third 105 mm howitzer battalion, and the 155 mm howitzer battalion was formed from the 155 mm howitzer regiment. The engineer, medical, and quartermaster regiments were reorganized into battalions. In 1942, divisional quartermaster battalions were split into ordnance light maintenance companies and quartermaster companies, and the division's headquarters and military police company, which had previously been a combined unit, was split. The 84th Infantry Division was ordered into active military service on 15 October 1942, at Camp Howze, Texas, about 60 miles north of Dallas. 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. 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. 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). , 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. 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.

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 airborne reserve command for the Army. Five years later, on 1 March 1952, the division was reorganized again, this time as the 84th Infantry Division composed of three regiments—the 274th, 334th, and 339th. In 1959, the division became the 84th Training Division, changing its subordinate units 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. == Organization ==

The 84th Training Command is a subordinate functional command of the United States Army Reserve Command.
