The 3rd Brigade Combat Team, 10th Mountain Division (LI), preserves the highest possible decisive action readiness in order to protect our nation and its vital strategic interests. We remain “Ready Now and Relevant Tomorrow.”
The 3rd Brigade Combat Team, 10th Mountain Division (LI) was established Sept. 16, 2004, at Fort Drum, New York.
The 1st Battalion, 32nd Infantry Regiment; 2nd Battalion, 87th Infantry Regiment; 4th Battalion, 25th Artillery Regiment; 3rd Squadron, 71st Cavalry Regiment; 710th Brigade Support Battalion; and 3rd Brigade Special Troops Battalion were brought together to form the Spartans of the 3rd Brigade Combat Team, 10th Mountain Division (LI). They served in both the Regional Command East and the Regional Command South areas of responsibility in Afghanistan.
In February 2006, the brigade deployed to Afghanistan in support of Operation Enduring Freedom VII and VIII, where they fought the Taliban in the mountainous terrain of the Afghan-Pakistani border.
In January 2009, Soldiers of the Spartan Brigade deployed again to Afghanistan, returning to RC-East, where they were tasked with providing security for the Logar and Wardak provinces as well as the southern entrance to the country’s capital.
In March 2011, the Spartan Brigade found itself called upon to deploy to Afghanistan again. The 3rd BCT Soldiers were sent to Kandahar Province, the RC-South area of responsibility. The brigade was responsible for opening 22 schools and three medical clinics, as well as securing and refurbishing more than 50 kilometers of Highway 1, the national highway for southern Afghanistan.
In October 2013, the Spartan Brigade embarked on its final deployment to Afghanistan. The 3rd BCT deployed once again to Regional Command East, but this time as an advise and assist brigade.
In August 2014, the brigade inactivated most of its elements at Fort Drum and reactivated in February 2015 at Fort Polk, Louisiana, using the assets of the 4th Brigade Combat Team ("Patriots"), 10th Mountain Division (LI).
In October 2015, the Patriot Brigade deployed to Afghanistan in support of Operation Resolute Support. Brigade Soldiers worked closely with the Afghan army, air force, and police forces while focusing on advise and assist missions in an effort to combat the insurgency. They returned to Fort Polk in June 2016.
While participating in the Army’s Associated Unit pilot program, the Patriot Brigade became associated with the 36th Infantry Division, Texas National Guard in September 2016. Soldiers’ shoulder sleeve insignia, unit placards, and official correspondence were switched from the 10th Mountain Division insignia to the 36th Infantry insignia, known as the “Texas T.” The pilot program was set to endure until September 2019 when an assessment will be made on how the program could expand.
In August 2017, the unit deployed to the Republic of Iraq in support of Operation Inherent Resolve. Members of the brigade teamed with multiple nations and the 1st Armored Brigade of Fort Bliss, Texas, to eradicate ISIS forces within the northern Iraqi desert and surrounding areas. After redeploying to Fort Polk in June 2018, the unit prepared to stand as a quick reactionary force for incidents that might occur around the globe.
