The history of the 45th Brigade Combat Team can be traced back to 1890 with the formation of the Militia of the Territory of Oklahoma.[3] That militia was mobilized in 1898 during the Spanish–American War but never deployed. In 1916 the First Oklahoma Infantry Regiment deployed for border security duty during the Mexican Border Conflict. In 1917, the First Oklahoma Infantry Regiment, reassigned as part of the 142nd Infantry Regiment of the 36th Division fought in the final month of World War I.[3]

On 19 October 1920, the Oklahoma State militia was organized as part of the 45th Infantry Division along with troops from Arizona, Colorado, and New Mexico.[5] The division was organized and federally recognized as a US Army unit on 3 August 1923 in Oklahoma City, Oklahoma.[2] Prior to World War II, the division was called on many times to maintain order in times of disaster and to keep peace during periods of political unrest. Oklahoma Governor John C. Walton used division troops to prevent the State Legislature from meeting when they were preparing to impeach him in 1923. Governor William H. Murray called out the guard several times during the depression to close banks, distribute food and once to force the State of Texas to keep open a free bridge over the Red River which Texas intended to collect tolls for, even after federal courts ordered the bridge not be opened.

The division would go on to see combat in World War II.[3] The division was active for over five years, participating in eight campaigns, four amphibious assaults, for a total of 511 days of combat.[3] Following World War II the division became an all-Oklahoma organization. In 1950, the division was also called into service during the Korean War, as one of four national guard divisions active during the war. The Division participated in four campaigns and sustained continuous combat operations for 429 days.[3]

In 1968, the division was disbanded and the 45th Infantry Brigade (Separate) was formed in its place.[6] The 45th Brigade assumed all of the 45th Division's lineage and campaign participation credit, including its shoulder sleeve insignia featuring a Thunderbird, a common Native American symbol, as a tribute to the south-western United States region which had a large population of Native Americans.[7] The brigade also assumed the division's nickname, "Thunderbirds".[1] The division's three subordinate brigades were disbanded as a part of the organization, and were not affiliated with the 45th Infantry Brigade (Separate).[8] The brigade's headquarters was subsequently relocated to Edmond, Oklahoma.[6] In 1971 the brigade received its distinctive unit insignia.[7]

The brigade did not participate in any overseas combat operations through the 1970s or 1980s, as the size of the active duty force negated the need for National Guard formations to be deployed during the relatively small contingencies of that period. However, the 45th did participate in REFORGER (Certain Strike) in September 1987.[9] The brigade was primarily used to train active duty units and other general peacetime missions within the United States.[3] In 1991, the brigade became affiliated with the 1st Cavalry Division, providing training services for the division soldiers.[10]

In 1994, the brigade was selected as one of fifteen "enhanced" separate brigades of the Army National Guard, featuring authorization to recruit 10% above required manning levels, a requirement to attend one of the Combat Training Centers not less than once every eight years, and ready to deploy within 90 days in case of emergencies.[3][11] In 1997, the brigade was integrated under the command structure of the 7th Infantry Division (which also included the 39th Infantry Brigade-Arkansas and the 41st Infantry Brigade-Oregon) allowing the 7th Infantry Division to provide training assistance and support for the brigade's activities should it be deployed, and potentially command and control when deployed, but that was never tested.[10] In 1996, the brigade's garrison was relocated back to Oklahoma City.[5]

In 1999, approximately 250 soldiers of the brigade were deployed to Bosnia in support of NATO forces seeking to stabilize the country in the wake of the Bosnian War. Soldiers of the brigade were among the first National Guard units to see front-line patrolling duty in the conflict, a job held exclusively by active duty units until that time.[12]

The brigade trained for a rotation in the Joint Readiness Training Center at Fort Polk, Louisiana throughout 2000 and 2001, before deploying to the center in June 2002.[10] The brigade received praise from the JRTC exercise commander, 7th Infantry Brigade Commander, Major General Edward Soriano, and the United States Army Chief of Staff, General Eric Shinseki, as performing the mission better than many brigades before it.[10] The 45th Infantry Brigade's performance at the Joint Readiness Training Center laid the groundwork for securing the first national guard infantry brigade deployment to a combat zone since the Korean War.

In January 2003, components of the 45th Infantry Brigade were deployed to Saudi Arabia and Kuwait. Approximately 230 light infantry soldiers from A Company and B Company, 1st Battalion, 179th Infantry Regiment composed Task Force Ironhorse under the United States Army Central Command (ARCENT).[13][14] Their primary mission leading up to the invasion of Iraq was to provide security for Patriot missile sites defending the respective countries from impending SCUD missile attacks.[14] In March 2003, Company A was ordered from the area in and around Riyadh to the northern border cities of Tabuk and Arar, Saudi Arabia in defense of Iraqi retaliation and security of strategically redeployed Patriot Missile sites. Company B was ordered to advance into Iraq from the Kuwaiti border to provide security for ammo caches and forward operating Patriot missile sites. Task Force Ironhorse was the first deployment of Oklahoma National Guard infantry soldiers to a combat zone since the Korean War (members of the Oklahoma National Guard deployed during Desert Storm as Field Artillery units). Task Force Ironhorse completed their mission and returned in August 2003.

On 19 September 2003, the 45th Infantry Brigade, under the command of Brigadier General Thomas P. Mancino, was mobilized to deploy to Afghanistan in support of Operation Enduring Freedom, assuming command of Task Force Phoenix II from 2nd Brigade, 10th Mountain Division.[10] The initial training for the mission was located at Fort Carson, Colorado. Task Force Phoenix II consisted of the Headquarters and Headquarters Company (HHC), C/1-179 Infantry Battalion for convoy and base security, HHC/700th Support Battalion for base support and convoy missions, the 136th Regional Training Institute of the Texas National Guard, 3 embedded training teams (ETT's). The 1st ETT was composed of officers, NCO's and soldiers from the 1–179 Infantry Battalion headquartered in Stillwater, Oklahoma. The 2nd ETT was composed of officers, NCO's and soldiers from the Vermont National Guard and the 3rd ETT was composed of officers, NCO's and soldiers from the South Carolina National Guard. In April 2004, 350 soldiers from the brigade's 1st Battalion, 279th Infantry Regiment also deployed to Joint Task Force Phoenix.[15] The mission of Task Force Phoenix II was to 1) Embed training teams into the Afghan National Army to provide training assistance, mission support, and administrative pay support 2) Assume the duties of the Office of Military Cooperation-Afghanistan (OMC-A) 3) Establish the Kabul Military Training Center (KMTC) 4) Mentor the Central Corps Commander and Command Group 5) Establish and maintain postal operations for the eastern sector 6) Conduct convoy resupply missions and 7) Establish the Afghan National Army Supply Depot. During this rotation, the brigade grew the size of the Afghan National Army to over 14,000 as well as fielding a corps-sized force ahead of schedule.[16] In August 2004, the brigade was replaced in this mission by the 76th Infantry Brigade, and subsequently returned home to the United States.[16]

In March 2006, the 1–180th Cavalry (still infantry in '06) deployed as part of Task Force Phoenix V. They were attached to the 41st BCT (Oregon ARNG). They returned in June 2007. In April 2007, the brigade was alerted that it could be deployed to Iraq in support of Operation Iraqi Freedom by the end of the year. Four months later they were alerted that they would be heading to Iraq in 2008.[17] The brigade mobilized in October of that year and trained in infantry techniques at army posts in Oklahoma and Arkansas. The 39th Infantry Brigade was also alerted for deployment during this time[17] and deployed to Iraq in late 2007.[18] During its rotation, the brigade was charged with turning over military facilities and Forward Operating Bases to the Iraqi Army as well as the Iraqi Police Force. The brigade returned to the United States in October 2008.[18]

In October 2007, the 45th Infantry Brigade Combat Team deployed to Iraq in support of Operation Iraqi Freedom under the command of Brigadier General General Myles L. Deering for a one-year deployment.

The 45th IBCT deployed to Afghanistan in 2011 and reunited with the 201st Corps of the ANA, as partners this time, in combined combat operations against insurgent forces in Eastern Afghanistan[19] suffering the loss of 14 Soldiers[20] but making significant progress in disrupting and destroying insurgent operations while continuing to mentor the ANA and progressively handing off security missions to them. The full brigade mobilized in April 2011, but a late change in the mission diverted the 180th Cavalry and 160th Field Artillery to separate missions to support Iraq operations from Kuwait. The brigades deployment is covered in the 2016 documentary Citizen Soldier.[21]

Additionally, elements of the 45th Brigade have deployed to Egypt (1–180th Infantry Multinational Force and Observers (MFO)), Kuwait (245th Military Intelligence Co OIF), and for separate rotations to Iraq (245th Engineer Co OIF) and Afghanistan (1–180th Infantry Task Force Phoenix V).

On 1 September 2005, the 45th Infantry Brigade, under the command of Brigadier General Myles L. Deering, was mobilized to deploy to New Orleans, Louisiana in support of Hurricane Katrina disaster relief efforts. Within hours, the 45th Infantry Brigade was given the designation "Task Force Oklahoma" and additional units were assigned from the Oklahoma National Guard to the task force. The first units assigned to Task Force Oklahoma (1345 Transportation Company and HHB/1-171 Field Artillery Battalion) arrived in New Orleans within 24 hours of Hurricane Katrina making landfall on 30 August 2005. The rest of the brigade, from Oklahoma, made it to New Orleans, via ground convoy, through Texas on 31 August 2005. Other units arrived via ground convoy or through the air, landing at Belle Chasse Naval Air Station

The 1345th Transportation Company and the 1st Battalion, 171st Field Artillery were among the first military units to arrive in New Orleans and stage out of the Morial Convention Center and the Louisiana Superdome. The task force headquarters was established at the Wal-Mart parking lot at 1901 Tchoupitoulas Street and street by street search and rescue operations began in earnest on 1 September 2005. At the time, this was the largest mobilization and deployment of the 45th since 1950. The 45th Infantry Brigade was eventually relieved of its responsibilities in New Orleans and returned to Oklahoma on 15 October 2005.
