3rd Brigade, 78th Division (Training Support)
The 3rd Brigade, 78th Division (Training Support) was inactivated in 2009 as part of the reorganization of the 78th Division (Training Support) to the 78th Training Brigade.
3rd Brigade, 78th Division (Training Support) was located in Devens, Massachusetts, approximately one hour west of Boston. The Brigade provided a Tri-Component structure (Active, Reserve and National Guard) for training support assistance and evaluations for National Guard and Reserve Units throughout New England.
The 3rd Brigade, 78th Division (Training Support) was first constituted on 5 August 1917 in the National Army as the 303rd Engineers and assigned to the 78th Division. The unit was organized in September 1917 at Camp Dix, New Jersey. The 303rd Engineers participated in 3 campaigns during the Great War as part of the 78th Division: St. Mihiel, Meuse-Argonne, and Lorraine 1918. After the war, the unit was demobilized on 12 June 1919 at Camp Dix, New Jersey.
The unit was reconstituted on 24 June 1921 in the Organized Reserves as the 303rd Engineers and assigned to the 78th Division (later redesignated as 78th Infantry Division). It was organized in November 1921 with Headquarters at Paterson, New Jersey. The unit was reorganized and redesignated (less 2nd Battalion) on 20 February 1942 as the 303rd Engineer Battalion. 2nd Battalion, 303rd Engineers thereafter had a separate lineage. The Battalion was ordered into active military service on 15 August 1942 and reorganized at Camp Butner, North Carolina. It was concurrently redesignated as the 303rd Engineer Combat Battalion. Deployed to the European Theater of Operations during World War II, the Battalion participated in 3 campaigns: Rhineland, Ardennes-Alsace, and Central Europe. After the war it was inactivated on 13 June 1946 in Germany.
The 303rd Engineer Combat Battalion was reactivated on 21 February 1947 at Newark, New Jersey. The unit was reorganized and redesignated on 15 December 1952 as the 303rd Engineer Battalion. During this period, the Organized Reserves was redesignated on 25 March 1948 as the Organized Reserve Corps, which was in turn redesignated on 9 July 1952 as the Army Reserve. The Battalion remained a part of this organization throughout the redesignations. The Battalion's Headquarters' location was changed on 1 June 1954 to East Orange, New Jersey and again on 9 January 1959 to Newark, New Jersey. The unit was disbanded entirely (less Companies A and B) on 1 May 1959 at Newark, New Jersey. Companies A and B, 303rd Engineer Battalion thereafter had separate lineages.
Headquarters, 303rd Engineer Battalion was reconstituted on 24 November 1967 in the Army Reserve as Headquarters, 3rd Brigade, 78th Division (Training) and activated on 31 January 1968 at Kearny, New Jersey. The Brigade was inactivated on 30 June 1973 at Kearny, New Jersey.
The unit was redesignated on 1 October 1993 as Headquarters, 3d Brigade, 78th Division (Exercise), and activated at Fort Devens, Massachusetts.
The unit was reorganized and redesignated on 17 October 1999 as Headquarters, 3rd Brigade, 78th Division (Training Support) and allotted to the Regular Army at Devens, Massachusetts. On 14 September 1999, 3rd Support Brigade (Training Support) began the process of reflagging as 3rd Brigade, 78th Division (Training Support). This unit had been reactivated on 30 October 1997 to take the place of the Readiness Group Devens, which had existed since General Order 339, Headquarters, United States Continental Army Command, dated 21 June 1973 had directed the organization of US Army Readiness Region III, effective 1 July 1973. Organization of the Army Readiness Regions and their subordinate Readiness Groups was a historic first. Never before had a single organization been responsible for providing assistance to both the Army Reserve and Army National Guard. Prior to 1985, the title of commander was not authorized. On 18 January 1985, the title of commander was approved and Colonel Jamo Powell became the first to hold that position.
Operations Desert Shield and Desert Storm provided the opportunity for Readiness Group Devens to perform it's wartime mission of activating a Mobilization Assistance Team. The Group ultimately was responsible for preparing over 3,500 Reserve Component soldiers in over 35 designated units for deployment. Acronyms, methodology, doctrine, mission priorities and organizational structures had evolved over time. This function remained largely unchanged through the reflagging of the unit to the 3rd Support Brigade and then to 3rd Brigade, 78th Divison (Training Support). This Brigade's mission was to provide assistance and instruction to Reserve Component units throughout the New England region, whether assisting in the deployment of Reserve Component units to locations like Bosnia in support of Operation Joint Endeavor, or providing humanitarian assistance and disaster relief to the 6 New England States.
