The 3rd Brigade, 75th Division is a mission command training brigade assigned to the 75th Division (Mission Command Training). It is based at Fort Sheridan Illinois.

The 3rd Brigade, 75th Division (Mission Command Training) was first constituted on 24 December 1942 in the Army of the United States as the 275th Engineer Combat Battalion and activated on 15 April 1943 at Fort Leonard Wood, Missouri. During the Second World War, the Battalion participated in 3 campaigns in the European Theater of Operations: Rhineland, Ardennes-Alsace, and Central Europe. After the end of the Second World War, the Battalion was inactivated on 14 November 1945 at Camp Patrick Henry, Virginia.

The unit was allotted on 21 February 1952 to the Organized Reserve Corps and activated on 1 March 1952 with Headquarters at Shreveport, Louisiana. The Organized Reserve Corps was redesignated on 9 July 1952 as the Army Reserve and the Battalion remained a part of the organization. The unit was reorganized and redesignated on 6 April 1953 as the 275th Engineer Battalion and inactivated on 24 June 1954 at Shreveport, Louisiana.

Headquarters, 275th Engineer Battalion was consolidated on 17 October 1999 with Headquarters, 3rd Brigade, 75th Division (Exercise), which had been activated on 1 October 1993 at Fort Worth, Texas. The consolidated unit was reorganized and redesignated as Headquarters, 3rd Brigade, 75th Division (Training Support) and allotted to the Regular Army at Fort Riley, Kansas. The remainder of 275th Engineer Battalion was concurrently disbanded.

The Brigade's mission was to provide training support to Combat Support-Combat Service Support (CS-CSS) Reserve Component units in Kansas, Nebraska, Iowa, and Missouri and Army Aviation Reserve Component units in the Fifth US Army Area of Responsibility to attain and sustain individual and collective pre-mobilization readiness. On order, the Brigade would provide Military Support to Civil Authorities (MSCA) in FEMA Region VII. It could assess and/or assist mobilization readiness on selected units as directed. It could also, on order, execute the Mobilization Assistance Team (MAT) mission.

The 3rd Brigade, 75th Division (Training Support) was a training support brigade formed under the tri-component concept for Actice Component/Reserve Component support. By the early 2000s, the Brigade consisted of 5 training support battalions and one logistics support battalion spread across 4 states. 2nd Battalion (Aviation), 291st Regiment was also located at Fort Riley, while 2nd Battalion (CS-CSS), 383rd Regiment was located at Fort Leavenworth, Kansas. 1st Battalion (Aviation), 291st Regiment was located at Fort Hood, Texas. 1st Battalion, (CS-CSS), 383rd Regiment was located in Des Moines, Iowa. 3rd Battalion (Logistics Support), 382nd Regiment and 3rd Battalion (CS-CSS), 383rd Regiment were both located in Missouri, at Fort Leonard Wood and in St. Louis respectively. Two of the Brigade's assigned battalions provided support and assistance to aviation units throughout the Fifth US Army area and the remaining 3 provide support and assistance to CS-CSS units in Kansas, Iowa, Missouri and Nebraska.

In 2000 2nd, 3rd, and 4th Brigades, 75th Division provided training support and mobilization assistance for a client base composed of 298 Priority and 643 Traditional units throughout the US Army Reserve and Army National Guard.

The Army's transformation in the 2000s necessitated restructuring the roles and missions of First US Army and Fifth US Army to support reserve component modularity and the Army Force Generation process known as Army Force Generation (ARFORGEN). First US Army's training mission expanded on 16 January 2006 to include training, readiness oversight and mobilization for US Army Reserve and National Guard units throughout the continental United States and two US territories. The transition of the expanded geographic mission began in mid-December 2005 with the transfer of authority between First US Army and Fifth US Army for the Western United States. Previously, First Army trained, mobilized and deployed US Army Reserve and National Guard units in the eastern United States, Puerto Rico and the US Virgin Islands. The 75th Division was assigned directly to US Army Reserve Command as a training command.

Though its subordinate units were reassigned to elements of First US Army, 3rd Brigade, 75th Division remained active, reorienting along with the rest of the Division to the Mission Command Training role. The Brigade was subsequently relocated to Fort Sheridan, Illinois.
