45th Infantry Brigade Combat Team ( United States ) The 45th Infantry Brigade Combat Team ( " Thunderbird " ) is a modular infantry brigade combat team of the United States Army headquartered in Norman , Oklahoma . It is a part of the Oklahoma Army National Guard . Formed from elements of the disbanded 45th Infantry Division which saw action during World War II and the Korean War , along with the 45th Field Artillery Group ( today ' s 45th Fires Brigade ) and 90th Troop Command , the 45th Infantry Brigade was activated in 1968 and assigned to training duties for active duty army units until 1994 when the 45th was selected as one of 15 " enhanced brigades " . The brigade deployed as part of the UN peacekeeping force in the wake of the Bosnian War , with C Company , 1 - 179th Infantry being among the first National Guard units to see duty there . In 2003 , A Co 1 - 179 deployed to Saudi Arabia while B 1 - 179 deployed to Kuwait to provide security for Patriot missile sites . During the invasion of Iraq , B Co 1 - 179 pushed North of Baghdad establishing a foothold in Taji Iraq . Later that year , the 45th deployed to Afghanistan to train soldiers of the Afghan National Army which was followed by a deployment to Iraq to assist in the turning over of American military bases to Iraqi forces . A second brigade deployment to Afghanistan in 2011 assigned the brigade to full - spectrum operations for the first time since the 1950s . The brigade received all heraldry , lineage and honors from the 45th Infantry Division , including its shoulder sleeve insignia and campaign streamers for combat in World War II and Korea . It has since received several of its own decorations for participation in the subsequent conflicts . Organization . The brigade is a subordinate unit of the Oklahoma Army National Guard , headquartered in Norman , OK . The brigade commands six battalion s . These units are the 1st Squadron , 180th Cavalry Regiment , 700th Brigade Support Battalion , 1st Battalion , 179th Infantry Regiment , 1st Battalion , 160th Field Artillery Regiment , 1st Battalion , 279th Infantry Regiment , and 45th Brigade Special Troops Battalion . 45th Infantry Division . 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 . 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 . On 19 October 1920 , the Oklahoma State militia was organized as the 45th Infantry Division of the Oklahoma Army National Guard and organized with troops from Arizona , Colorado , New Mexico , and Oklahoma . The division was organized and federally recognized as a US Army unit on 3 August 1923 in Oklahoma City , Oklahoma . 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 as one of four national guard divisions active during the war . The division was active for over five years , participating in eight campaigns , four amphibious assault s , for a total of 511 days of combat . Following World War II the division became an all - Oklahoma organization . In 1950 , the division was also called into service during the Korean War , participating in four campaigns and fighting for 429 days . Cold War years . In 1968 , the division was disbanded and the 45th Infantry Brigade ( Separate ) was formed in its place . 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 . The brigade also assumed the division ' s nickname , " Thunderbirds " . The division ' s three subordinate brigades were disbanded as a part of the organization , and were not affiliated with the 45th Infantry Brigade ( Separate ) . The brigade ' s headquarters was subsequently relocated to Edmond , Oklahoma . In 1971 the brigade received its distinctive unit insignia . The brigade did not participate in any overseas 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 . Instead , the brigade was used to train active duty units , and other general peacetime missions within the United States . In 1991 , the brigade became affiliated with the 1st Cavalry Division , providing training services for the division soldiers . Desert Storm . On 19 September 1990 the 2120ths Supply and Service Company located in Wewoka , Oklahoma was called up for active duty in support of Desert Shield . This was the first of fourteen units from the 45th called up in support of the action . Many of the units were sent to Saudi Arabia to provide support for the regular army in Desert Shield and Desert Storm . Enhanced brigade . 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 and 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 . In 1997 , the brigade was integrated under the command structure of the 7th Infantry Division , allowing the 7th Division to provide oversight and support for the brigade ' s activities should it be deployed , and potentially command and control when deployed , but that was never tested . In 1996 , the brigade ' s garrison was relocated back to Oklahoma City . In 2000 – 2001 several hundred 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 . 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 throughout 2002 and early 2003 . The brigade received praise from center commanders as performing the mission better than many brigades before it . After its rotation , the brigade trained the 39th Infantry Brigade of the Arkansas Army National Guard , which saw the next rotation in the JRTC . The 39th Brigade was also under the command of the 7th Infantry Division . Iraq and Afghanistan . 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 comprised Task Force Ironhorse under the United States Army Central Command ( ARCENT ) . 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 . 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 soldiers to a combat zone since the Korean War . Task Force Ironhorse completed their mission and returned in August 2003 . A Company , 1 / 179 Infantry was the last mission - oriented light infantry unit from the United States to set foot in Saudi Arabia . In fall of 2003 , the 45th Infantry Brigade was deployed to Afghanistan in support of Operation Enduring Freedom , assuming command of Task Force Phoenix II from 2nd Brigade , 10th Mountain Division . The purpose of the soldiers ' deployment was to assist in training Afghan security forces . Over the next few years , soldiers of the 45th Infantry Brigade , including its Headquarters and Headquarters Company , would deploy in support of this mission . In April 2004 , 350 soldiers from the brigade ' s 1st Battalion , 279th Infantry Regiment also deployed to Joint Task Force Phoenix . 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 . In August 2004 , the brigade was replaced in this mission by the 76th Infantry Brigade , and subsequently returned home to the United States . The brigade spent three years back home , and in that time transformed into an infantry Brigade Combat Team as a part of a new transformation plan for the Army . In March 2006 , the 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 . 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 and deployed to Iraq in late 2007 . 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 . 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 suffering the loss of 14 Soldiers but making significant pregress in disrupting and destroying insurgnet 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 . 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 ) as well as various homeland security missions . Honors . The brigade received all of the honors previously accorded to the 45th Infantry Division , including its campaign streamers , which give credit for participation in combat . Additionally , several of these streamers contain the Arrowhead device , signifying the division ' s participation in amphibious assault s .
