Organizational Summary:

The 27th Brigade Support Battalion was activated on 18 October 2005 and receives its lineage from the 27th Main/Maintenance Support Battalion that was constituted on 01 September 1921 in the regular Army as the 27th Ordnance Company as an element of the newly formed 1st Cavalry Division. Activated 20 days later at Ft. Bliss, Texas, the 27th Ordnance Company’s mission was to provide furrier and blacksmith support for the horses and equipment of the division.

On 02 March 1943, the 27th Ordnance Company was reorganized and redesignated the 27th Ordnance Medium Maintenance Company. Thereafter, the unit proceeded to the Southwest Pacific Theater with the 1st Cavalry Division where it established a reputation for professionalism in its duty performance. On 25 March 1949, the company was again reorganized and redesignated as the Headquarters and Headquarters Detachment, 27th Ordnance Battalion, with the remainder of the battalion reorganized concurrently.

During the Korean War, the battalion was redesignated as the 27th Maintenance Battalion. It was reorganized with the Division in 1965 as part of the first airmobile division. Shortly thereafter, it was deployed to Vietnam and served six years with the Division in the Vietnam Conflict. There it earned the Vietnamese Civil Action Honor Medal, and the Meritorious Unit Commendation and Streamer, among many others.

The 27th Maintenance Battalion had maintained its dedicated and professional support to the First Team willingly for almost 64 years before being deactivated and reorganized into the 4th Main Support Battalion on 20 June 1985. Elements of the 15th Medical Battalion and the 15th Supply and Transport Battalion were concurrently reorganized into this new battalion. Although shortly lived, the 4th Main Support Battalion quickly established itself as a dedicated and successful support unit in its superior support of the 1st Cavalry Division at numerous field exercises and several National Training Center Rotations at Ft. Irwin, California. On 01 May 1987, the battalion was reinstated as the 27th Main Support Battalion, assuming its colors and carrying on its proud tradition of the past.

In August 1990, the 1st Cavalry Division was alerted for deployment to Southwest Asia as part of the joint forces participating in Operations Desert Shield. The focus at the time was the defense of Saudi Arabia against potential Iraqi attack. Arriving in Saudi Arabia in September 1990, the 27th Support Battalion moved to Northern Saudi Arabia, West of Hafar Al Batin. At the start of the ground war, a heavy forward support team moved into Iraq and set up operations and logistical release point near the Kuwaiti border.

On 18 October 2005, the 27th Main Support Battalion was redesignated and activated as the 27th Brigade Support Battalion, 4th Brigade, 1st Cavalry Division at Ft. Bliss, Texas under the Army's modularity transformation reorganization. The Battalion now provides all logistical support to combat units assigned to the 4th Brigade Combat Team.

In March 2008, the 4th Brigade Combat Team (Cobras) from the 4th Infantry Division became the 4th Brigade Combat Team, 1st Cavalry Division on Cooper Field on Ft. Hood, Texas. The former Longknife Brigade reflagged to the 1st Armored Division. From June 2008 to June 2009, the battalion deployed to southern Iraq as part of the 4th Brigade Combat Team, 1st Cavalry Division's support to Operation IRAQI FREEDOM 08-10.
