## Heraldry

The 3rd Brigade is a subordinate component of the 1st Cavalry Division and wears the same shoulder sleeve insignia.

## Initial organization

The 3rd Brigade, 1st Cavalry Division was first constituted on 29 August 1917. It was organized in December 1917 as Headquarters, 3rd Brigade, an element of the 15th Cavalry Division. The brigade demobilized on 15 July 1919. The brigade was reconstituted on 10 August 1921, joining the newly constituted 1st Cavalry Division. Never officially reorganized, the Brigade remained on inactive status until its activation on 15 October 1940.

## World War II

The brigade was converted and redesignated as HHC, 9th Armored Division Trains, and the unit deployed to the European Theater where it received campaign participation credit for the operations in Rhineland, Ardennes-Alsace, and Central Europe. The unit was awarded two Meritorious Unit Commendations with streamers embroidered Europe 1944 and Europe 1945. Following World War II, the unit returned to the United States and was inactivated.

## South Korea

The brigade remained inactive until 15 July 1963, when it was relieved from assignment to the 9th Armored Division, converted and redesignated as HHC, 3rd Brigade, 1st Cavalry Division. The brigade was activated on 1 September 1963, with the Division on station in Korea at the Korean Demilitarized Zone.

## Vietnam War

In July 1965, the division colors moved to Fort Benning and underwent reorganization as an airmobile unit. No soldiers moved, and the soldiers remaining in Korea put on the patch of the 2nd Infantry Division. The brigade was filled with soldiers from the 2nd Infantry Division and the 11th Airborne Division.
The 3rd Brigade, 1st Cavalry Division (Airmoble) sailed from Charleston, South Carolina to Qui Nhơn, Republic of Vietnam on 17 September 1965. The first major action undertaken by the brigade began on 10 October 1965, and was followed by participation in the Battle of Ia Drang (14 November, 15,17) officially known as the Pleiku Campaign. The 1st Cavalry Division (Airmobile) received the Presidential Unit Citation for the period 23 October to 26 November 1965.
While the rest of the division left South Vietnam at the end of April 1971, the 3rd Brigade was formed into a separate unit and assumed operational control of the old 1st Cavalry Division area of operations in South Vietnam until 1972.
On 20 June 1972 in a ceremony attended by COMUSMACV General Creighton Abrams the brigade stood down and left South Vietnam for Fort Hood, Texas, to rejoin the 1st Cavalry Division. When its colors arrived at Fort Hood on 29 June 1972, the unit officially became the "Greywolf" Brigade, named after General George Crook, considered the U.S. Army's greatest Indian fighter. The brigade underwent a change from an airmobile configuration to an infantry brigade (heavy or mechanized infantry). The "Greywolf" Brigade remained with the division until its inactivation in 1980.
The 3rd Brigade was composed of the following elements:
* HHC, 3d Brigade
* 1st Battalion, 7th Cavalry
* 2nd Battalion, 7th Cavalry
* 5th Battalion, 7th Cavalry (added while the unit was in South Vietnam)
* F Troop, 9th Cavalry

## Post Operation Desert Storm

The brigade remained on the inactive roles until 21 May 1991, when the 1st "Tiger" Brigade, 2nd Armored Division was redesignated as the 3rd "GREYWOLF" Brigade, 1st Cavalry Division. Since that time, the brigade has participated in several National Training Center rotations, deployed task force sized elements to Kuwait, and in September 1996, conducted the first post- Desert Storm, no-notice, brigade-sized deployment to Kuwait in support of Operation Desert Strike.

While serving as the main regional force for Coalition efforts in the area it fell under the command of Multi-National Division-North (MND-N). During the 2006–2008 tour MND-N was commanded by the 25th Infantry Division and based out of COB Speicher in Tikrit. The brigade was a part of the controversial theater "extension" that increased all combat tours to 15 months. This pushed their re-deployment home from theater to December 2007.

The primary mission of the brigade was to continue to improve Iraqi Army and Police forces through an Advise and Assist mission. Their secondary mission was to conduct route security missions to assist in maintaining open ground lines of communication. Both missions would support the United States military forces eventual departure from Iraq in December 2011. On 17 December 2011, Greywolf's Special Troops Battalion was the last combat unit to redeploy from the war-torn nation, thus ending America's 9-year long war.
