The 45th Infantry Division was an infantry division of the United States Army, part of the Oklahoma Army National Guard, from 1920 to 1968. Headquartered mostly in Oklahoma City, the guardsmen fought in both World War II and the Korean War. They trace their lineage from frontier militias that operated in the Southwestern United States throughout the late 1800s.
The 45th Infantry Division guardsmen saw no major action until they became one of the first National Guard units activated in World War II in 1941. They took part in intense fighting during the invasion of Sicily and the attack on Salerno in the 1943 Italian Campaign. Slowly advancing through Italy, they fought in Anzio and in Monte Cassino. After landing in France during Operation Dragoon, they joined the 1945 drive into Germany that ended the War in Europe.
After brief inactivation and subsequent reorganization as a unit restricted to Oklahomans, the division returned to duty in 1951 for the Korean War. It joined the United Nations troops on the front lines during the stalemate of the second half of the war, with constant, low-level fighting and trench warfare against the People's Volunteer Army of China that produced little gain for either side. The division remained on the front lines in such engagements as Old Baldy Hill and Hill Eerie until the end of the war, returning to the U.S. in 1954.
The division remained a National Guard formation until its inactivation in 1968 as part of a downsizing of the Guard. Several units were activated to replace the division and carry on its lineage. Over the course of its history, the 45th Infantry Division sustained over 25,000 battle casualties, and its men were awarded nine Medals of Honor, twelve campaign streamers, the Croix de Guerre and the Republic of Korea Presidential Unit Citation.

With the outbreak of World War I, troops of the National Guard were formed into the units which exist today, with the Colorado Guard forming the 157th Infantry Regiment, the Arizona Guard forming the 158th Infantry Regiment, and the New Mexico Guard forming the 120th Engineer Regiment. These units were attached to the 40th Infantry Division and deployed to France where they were used as "depot" forces to provide replacements for front-line units. They returned home at the end of the war. The Oklahoma Guard units that would later become the 179th Infantry Regiment and 180th Infantry Regiment were assigned to the 36th Infantry Division and would earn a combat participation credit during the Meuse-Argonne Campaign (26 September – 11 November 1918) in France as the 142nd Infantry.
1923–1940 "Square" Organization 
On 19 October 1920, the Oklahoma State militia was organized as the 45th Infantry Division of the Oklahoma Army National Guard, and manned with troops from Arizona, Colorado, New Mexico, and Oklahoma. The division was formed and federally recognized as a National Guard unit on 3 August 1923 in Oklahoma City, Oklahoma. It was assigned the 89th Infantry Brigade of the Colorado and Arizona National Guards, and the 90th Infantry Brigade of the Oklahoma National Guard. As a consequence of these militia roots, when the division was properly organized, many of its members were marksmen and outdoorsmen from the remote frontier regions of the Southwestern United States. The division's first commander was Major General Baird H. Markham.
The 45th Infantry Division engaged in regular drills but no major events in its first few years, though the division's Colorado elements were called in to help quell a large coal mining strike. The onset of the Great Depression in the 1930s severely curtailed its funding for training and equipment. Major General Roy Hoffman took command in 1931, followed by Alexander M. Tuthill, Alexander E. McPherren in 1935, and William S. Key in 1936. In 1937, the division's troops were once again called up, this time to help manage a locust plague affecting Colorado.
The division's original shoulder sleeve insignia, approved in August 1924, featured a swastika, a common Native American symbol, as a tribute to the Southwestern United States region which had a large population of Native Americans. However, with the rise of the Nazi Party in Germany, with its infamous swastika symbol, the 45th Division stopped using the insignia. Following a long process of submissions for new designs, a new shoulder sleeve insignia, designed by a Carnegie, Oklahoma native named Woody Big Bow, featuring the Thunderbird, another Native American symbol, was approved in 1939.
In August 1941, the 45th Infantry Division took part in the Louisiana Maneuvers, the largest peacetime exercises in U.S. military history. It was assigned to VIII Corps with the 2nd Infantry Division and the 36th Infantry Division, camped near Pitkin, Louisiana. Still operating with outmoded equipment from World War I, the division did not perform well during these exercises. With poor weather and bad equipment, the undertrained 45th Infantry Division was criticized by officers who considered it "feeble". In spite of these deficiencies, less than one month later, the men were recalled to the active duty force, much to their chagrin, because of concerns of an impending U.S. entry into World War II.
World War II
On 16 September 1941, the 45th Infantry Division was federalized from state control into the regular army force. It was one of four National Guard divisions to be federalized, alongside the 30th Infantry Division, the 41st Infantry Division and the 44th Infantry Division, originally for a one-year period. Its men immediately began basic combat training at Fort Sill, Oklahoma. Throughout 1942, it continued this training at Camp Barkeley, Texas, before moving to Fort Devens, Massachusetts, to undergo amphibious assault training in preparation for an invasion of Italy. It then moved to Pine Camp, New York briefly for winter warfare training, but was hampered by continuously poor weather. In January 1943 it moved to Fort Pickett, Virginia, for its final training. The division moved to the Hampton Roads Port of Embarkation embarkation's Camp Patrick Henry to await combat loading on the transports.
The division's two combat commands, the 89th and 90th Brigades, were not activated, as the Army favored smaller and more versatile regimental commands for the new conflict. The 45th Infantry Division was instead based around the 157th, 179th, and 180th Infantry Regiments. Also assigned to the division were the 158th, 160th, 171st, and 189th Field Artillery Battalions, the 45th Signal Company, the 700th Ordnance Company, the 45th Quartermaster Company, the 45th Reconnaissance Troop, the 120th Engineer Combat Battalion, and the 120th Medical Battalion.
1942–1963 "Triangular" Organization
The division sailed from the Hampton Roads Port of Embarkation for the Mediterranean region on 8 June 1943, combat loaded aboard thirteen attack transports and five cargo attack vessels as convoy UGF-9 headed by the communications ship USS Ancon. By the time the 45th Division landed in North Africa on 22 June 1943, the Allies had largely secured the African theater. As a result, the division was not sent into combat upon arrival and instead commenced training at Arzew, French Morocco, in preparation for the invasion of Sicily. Allied intelligence estimated that the island was defended by approximately 230,000 troops, the majority of which were drawn mostly from weak Italian formations and two German divisions which had been reconstituted after being destroyed earlier. Against this, the Allies planned to land 180,000 troops, including the 45th Division, which was assigned to II Corps of the U.S. Seventh Army, under General George Patton, for the operation.
The division was subsequently assigned a lead role in the amphibious assault on Sicily, coming ashore on 10 July. Landing near Scoglitti, the southernmost U.S. objective on the island, the division advanced north on the U.S. force's eastern flank. After initially encountering resistance from armor of the German Herman Goering Division, the division advanced, supported by paratroopers of the 82nd Airborne Division who landed inland on 11 July. The 82nd paratroopers, conducting their first combat jump of the war, then set up to protect the 45th's flank against German counterattack, but without weapons to counter heavy armor, the paratroopers had to rely on support from U.S. armored units to repulse the German Tiger I tanks. As the division advanced towards its main objective to capture the airfields at Biscari and Comiso, German forces pushed back. For most of the first two weeks while the division moved slowly north, it encountered only light resistance from Italian forces fighting delaying actions. Italian and German forces resisted fiercely at Motta Hill on 26 July, however, and for four days the 45th Infantry Division was held up there. After this, division was allocated to drive towards Messina, being ordered by General Patton to cover the distance as quickly as possible. It spent a few days in that city, but on 1 August, the division was withdrawn from the front line for rest and rear-guard patrol duty, after which the division was assigned to VI Corps of the U.S. Fifth Army, under Mark Clark, in preparation for the invasion of mainland Italy.
On 3 September, Italy surrendered to the Allied powers. Hoping to occupy as much of the country as possible before the German Army could react, the U.S. Fifth Army prepared to attack Salerno. On 10 September 1943, the division conducted its second landing at Agropoli and Paestum with the 36th Infantry Division, on the southernmost beaches of the attack. Opposing them were elements of the German 29th Panzergrenadier Division and XVI Panzer Corps. Against stiff resistance, the 45th pushed to the Calore River after a week of heavy fighting. The Fifth Army was battered and pushed back by German forces until 20 September, when Allied forces were finally able to break out and establish a more secure beachhead. On 3 November it crossed the Volturno River and took Venafro. The division had great difficulty moving across the rivers and through the mountainous terrain, and the advance was slow. After linking up with the British Eighth Army, which had advanced from the south, the combined force, under the 15th Army Group, was stalled when it reached the Gustav Line. Until 9 January 1944, the division inched forward into the mountains reaching St. Elia, north of Cassino, before moving to a rest area.
Allied forces conducted a frontal assault on the Gustav Line stronghold at Monte Cassino, and VI Corps, British 1st Infantry Division included, was assigned to Operation Shingle, detached from the 15th Army Group to land behind enemy lines at Anzio on 22 January 1944. For this mission, CCA (Combat Command A) of the 1st Armored Division was attached to the 45th Infantry Division. Landing on schedule, VI Corps surprised the Germans, but Major General John P. Lucas's decision to consolidate the beachhead instead of attacking gave the Germans time to bring the LXXVI Panzer Corps forward to oppose the landings.
One regiment of the 45th (the 179th) went ashore with the landings. In company with the British 1st Division, they advanced north along the Anzio-Albano road and captured the Aprilia "factory", but encountered heavy resistance from German armored units a few miles further on. Lucas then ordered the rest of the division ahore. The 45th Division was deployed on the southeastern side of the beachhead, along the lower Mussolini Canal.
On 30 January 1944, when VI Corps advanced from the beaches, it encountered heavy resistance and took heavy casualties. VI Corps was stopped at the "Pimlott Line" (the perimeter of the beachhead), and the fight became a battle of attrition.
The first major German counterattack came in early February, was against British 1st Division. Two regiments of the 45th (the 179th and 157th) were sent to the Aprilia sector to reinforce the British. The 179th Infantry and a tank battalion of CCA tried to recapture Aprilia but were repulsed. Lucas then moved the rest of the 45th Division to the left-center of the perimeter, at Aprilia and along the west branch of the Mussolini Canal. For the next four months the 45th Infantry Division was mostly stuck in place, holding its ground during repeated German counterattacks, and subjected to bombardment from aircraft and artillery.
On 16 February, a major German attack struck the 45th, and nearly broke through the 179th Infantry on 18 February. Lucas sent famed Ranger leader Colonel William O. Darby to assume command of the 157th, and the Germans were repulsed.
On 23 May, VI Corps went on the offensive, breaking out of the beachhead to the northeast, with the 45th Division forming the left half of the attack. By 31 May, the German defenses were shattered, and the 45th Division turned northwest, toward the Alban Hills and Rome. On 4 June the 45th crossed the Tiber River below Rome, and entered the city along with other VI Corps troops. Men of the 45th Division were the first Allied troops to reach the Vatican.
On 16 June, the 45th Division withdrew for rest in preparation for other operations. At this time, VI Corps was attached to the Seventh United States Army, Sixth United States Army Group. The 45th, 36th, and 3rd Infantry divisions were pulled from the line in Italy in preparation for Operation Dragoon (formerly Anvil), the invasion of southern France. Dragoon was originally planned to coincide with the Normandy landings in the north, but was delayed until August because of a shortage of landing craft.
France and Germany
The 45th Infantry Division participated in its fourth assault landing during Operation Dragoon on 15 August 1944, at St. Maxime, in Southern France. The division landed its 157th and 180th regimental combat teams and captured the heights of the Chaines de Mar before meeting the 1st Special Service Force. The German Army, reeling from the Battle of Normandy, pulled back after a short fight, part of an overall German withdrawal to the east following the landings. Soldiers of the 45th Infantry Division engaged the dispersed forces of German Army Group G, suffering very few casualties. The Seventh Army, along with Free French forces, were able to advance north quickly. By 12 September, the Seventh Army linked up with the Third United States Army, advancing from Normandy, joining the two forces at Dijon. Against slight opposition, it spearheaded the drive for the Belfort Gap. The 45th Infantry Division took the strongly defended city of Epinal on 24 September. The division was then reassigned to V Corps for its next advance. On 30 September the division crossed the Moselle River and entered the western foothills of the Vosges, taking Rambervillers. It would remain in the area for a month waiting for other units to catch up before crossing the Mortagne River on 23 October. The division remained on the line with the Sixth United States Army Group, the southernmost of three Army Groups advancing through France.
After the crossing was complete, the division was relieved from V Corps and assigned to XV Corps. The division was allowed a one-month rest, resuming its advance on 25 November, attacking the forts north of Mutzig. These forts had been designed by Kaiser Wilhelm II in 1893 to block access to the plain of Alsace. The 45th Division next crossed the Zintzel River before pushing through the Maginot defenses. During this time much of the division's artillery assets were attached to the 44th Infantry Division to provide additional support. The 45th Infantry Division was reassigned to VI Corps on New Year's Day. From 2 January 1945, the division fought defensively along the German border, withdrawing to the Moder River. It sent half of its artillery to support the 70th Infantry Division. On 17 February the division was pulled off the line for rest and training. Once this rest period was complete, the division was assigned to XV Corps for the final push into German territory. The 45th moved north to the Sarreguemines area and smashed through the Siegfried Line, on 17 March taking Homburg on the 21st and crossing the Rhine between Worms and Hamm on the 26th. The advance continued, with Aschaffenburg falling on 3 April, and Nuremberg on the 20th. The division crossed the Danube River on 27 April, and liberated 32,000 captives of the Dachau concentration camp on 29 April 1945. The division captured Munich during the next two days, occupying the city until V-E Day and the surrender of Germany. During the next month, the division remained in Munich and set up collection points and camps for the massive numbers of surrendering troops of the German armies. The number of POWs taken by the 45th Division during its almost two years of fighting totalled 124,840 men. The division was then slated to move to the Pacific theater of operations to participate in the invasion of mainland Japan on the island of Honshu, but these plans were scrubbed before the division could depart after the surrender of Japan, on V-J Day.
After the war, courts-martial were convened to investigate possible war crimes by members of the division. In the first case, dubbed the Biscari massacre, American troops from C Company, 180th Infantry Regiment, were alleged to have shot 74 Italian and two German prisoners in Acate in July 1943 following the capture of an airfield in the area. Patton asked General Omar Bradley to get the case dismissed to prevent bad press, but Bradley refused. A non-commissioned officer later confessed to the crimes and was found guilty, but an officer who claimed he had only been following orders was acquitted.
In a second incident, the Army considered court-martialling several officers of the 157th Infantry Regiment under Lieutenant Colonel Felix L. Sparks after servicemen were accused of massacring German soldiers who were surrendering at the Dachau concentration camp in 1945. Some of the German troops were camp guards; the others were sick and wounded troops from a nearby hospital. The soldiers of the 45th Division who liberated the camp were outraged at the malnourishment and maltreatment of the 32,000 prisoners they liberated, some barely alive, and all victims of the Holocaust. After entering the camp, the soldiers found boxcars filled with dead bodies of prisoners who had succumbed to starvation or last-minute executions, and in rooms adjacent to gas chambers they found naked bodies piled from the floor to the ceiling. The cremation ovens, which were still in operation when the soldiers arrived, contained bodies and skeletons as well. Some of the victims apparently had died only hours before the 45th Division entered the camp, while many others lay where they had died in states of decomposition that overwhelmed the soldiers' senses. Accounts conflict over what happened and over how many German troops were killed. After investigating the incident, the Army considered court-martialling several officers involved, but Patton successfully intervened. Seventh Army was being disbanded and Patton had been appointed Military Governor of Bavaria, placing the matter in his hands. Some veterans of the 45th Infantry Division have said that only 30 to 50 German soldiers were killed and that very few were killed trying to surrender, while others have admitted to killing or refusing to treat wounded German guards.

During World War II, the 45th Division fought in 511 days of combat. Nine soldiers were awarded the Medal of Honor during their service with the 45th Infantry Division: Van T. Barfoot, Ernest Childers, Almond E. Fisher, William J. Johnston, Salvador J. Lara, Jack C. Montgomery, James D. Slaton, Jack Treadwell, and Edward G. Wilkin. Soldiers of the division also received 61 Distinguished Service Crosses, three Distinguished Service Medals, 1,848 Silver Star Medals, 38 Legion of Merit medals, 59 Soldier's Medals, 5,744 Bronze Star Medals, and 52 Air Medals. The division received seven distinguished unit citations and eight campaign streamers during the conflict. The division suffered 3,650 killed in action, 13,729 wounded in action, 3,615 missing in action, 266 captured, and 41,647 non-battle casualties for a total of 62,907 casualties during the war.
Most of the division returned to New York in September 1945, and from there went to Camp Bowie, Texas. On 7 December 1945, the division was deactivated from the active duty force and its members reassigned to other Army units. The following year, on 10 September 1946, the 45th Infantry Division was reconstituted as a National Guard unit. Instead of comprising units from several states, the post-war 45th was an all-Oklahoma organization. During this time the division was also reorganized and as a part of this process the 157th Infantry was removed from the division's order of battle and replaced with the 279th Infantry Regiment.
During this time, the U.S. Army underwent a drastic reduction in size. At the end of World War II, it contained 89 divisions, but by 1950, there were just 10 active divisions in the force, along with a few reserve divisions such as the 45th Infantry Division which were combat-ineffective. The division retained many of its best officers as senior commanders as the force downsized, and it enjoyed a good relationship with its community. The 45th in this time was regarded as one of the better-trained National Guard divisions. Regardless, by mid-1950 the division had only 8,413 troops, less than 45 percent[n 1] of its full-strength authorization. Only 10 percent of the division's officers and 5 percent of its enlisted men had combat experience with the division from World War II.
At the outbreak of the Korean War in June 1950, the U.S. Army looked to expand its force again to prepare for major conflict. After the North Korean People's Army invaded the Republic of Korea four understrength U.S. divisions on occupation duty in Japan were rushed to South Korea to stand alongside the Republic of Korea Army. These were the 7th Infantry Division, the 1st Cavalry Division, the 24th Infantry Division, and the 25th Infantry Division, which were all under the control of the Eighth United States Army. Due to drastic reductions in U.S. military spending following the end of World War II, these divisions were equipped with worn-out or obsolete weaponry and suffered from a shortage of anti-armor weapons capable of penetrating the hulls of the North Korean T-34 tanks.
Initially, the division was used to provide a pool of reinforcements for the divisions which had been sent to the Korean War theater, and in January 1951 it provided 650 enlisted fillers for overseas service. Later that month, it was given 4,006 new recruits for its three infantry regiments and artillery assets, and each unit created a 14-week training program to prepare these new soldiers for combat. Because of heavy casualties and slow reinforcement rates, the Army looked to the National Guard to provide additional units to relieve the beleaguered Eighth Army. At the time, the 45th Infantry Division was comprised overwhelmingly of high school students or recent graduates and only about 60 percent of its divisional troops had conducted training and drills with the division for a year or more. Additionally, only about 20 percent of its personnel had prior experience of military service from World War II. Nevertheless, the division was one of four National Guard divisions identified as being among the most prepared for combat based on the effectiveness of its equipment, training, and leadership. As a result, in February 1951, the 45th Infantry Division was alerted that it would sail for Japan.
In preparation for the deployment, the division was sent to Fort Polk, Louisiana, to begin training and to fill its ranks. After its basic training was complete, the division was sent to Japan in April 1951 for advanced training and to act as a reserve force for the Eighth United States Army, then fighting in Korea. The involvement of the National Guard in the fighting in Korea was further expanded when the 40th Infantry Division of the California Army National Guard received warning orders for deployment as well.
On 1 September 1951, the 45th Infantry Division was activated as the first National Guard division to be deployed to the Far East theater since World War II. Nevertheless, it was not deployed to Korea until December 1951, when its advanced training was complete. Following its arrival, the division moved to the front line to replace the 1st Cavalry Division, who were then delegated to the Far East reserve, having suffered over 16,000 casualties in less than 18 months of fighting.
Though the 45th remained de facto segregated as an all-white unit in 1950, individual unit commanders went to great lengths to integrate reinforcements from different areas and ethnicity into their units. By 1952, it was fully integrated. Additionally, in an effort to reduce the burden on the National Guard,[n 2] troops from the division were often replaced by enlisted and drafted soldiers from the active duty force. When it arrived in Korea, only half the division's manpower were National Guard troops, and over 4,500 guardsmen left between May and July 1952, continually replaced by more active duty troops, including an increasing number of African Americans. Though the division was no longer an "All-Oklahoma" unit, leaders opted to keep its designation as the 45th Infantry Division.[n 3]
By the time the division was in place, the battle lines on both sides had largely solidified, leaving the 45th Infantry Division in a stationary position as it conducted attacks and counterattacks for the same ground. The division was put under the command of Eighth Army's I Corps for most of the conflict. It was deployed around Chorwon and assigned to protect the key routes from that area into Seoul. The terrain was difficult and the weather was poor in the region. The division suffered its first casualty on 11 December 1951.
Initially, the division did not fare well, though it improved quickly. Its anti-aircraft and armor assets were used as mobile artillery, which continuously pounded Chinese positions. The 45th, in turn, was under constant artillery and mortar attack. It also conducted constant small-unit patrols along the border seeking to engage Chinese outposts or patrols. These small-unit actions made up the majority of the division's combat in Korea. Chinese troops were well dug-in and better trained than the troops of the inexperienced 45th, and it suffered casualties and frequently had to disengage when it was attacked.
In the division's first few months on the line, Chinese forces conducted three raids in its sector. In retaliation, the 245th Tank Battalion sent nine tanks to raid Agok. Two companies of Chinese forces ambushed and devastated a patrol from the 179th Infantry a short time later. In the spring, the division launched Operation Counter, which was an effort to establish 11 patrol bases around Old Baldy Hill. The division then defended the hill against a series of Chinese assaults from the Chinese 38th Army.
Final engagements and the end of the war
The 45th Infantry Division, along with the 7th Infantry Division, fought off repeated Chinese attacks all along the front line throughout 1952, and Chinese forces frequently attacked Old Baldy Hill into the fall of that year. Around that time, the 45th Infantry Division relinquished command of Old Baldy Hill to the 2nd Infantry Division. Almost immediately the Chinese launched a concentrated attack on the hill, overrunning the U.S. forces. Heavy rainstorms prevented the divisions from retaking the hill for around a month, and when it was finally retaken it was heavily fortified to prevent further attacks. The 245th Tank Battalion was sent to assault Chinese positions throughout late 1952, but most of the division held a stationary defensive line against the Chinese.
In early 1953, North Korean forces launched a large-scale attack against Hill 812, which was then under the control of K Company, 3rd Battalion, 179th Infantry. The ensuing Battle of Hill Eerie was one of a series of larger attacks by Chinese and North Korean forces which produced heavier fighting than the previous year had seen. These offensives were conducted largely in order to secure a better position during the ongoing truce negotiations. Chinese forces continued to mount concentrated attacks on the lines of the UN forces, including the 45th Infantry Division, but the division managed to hold most of its ground, remaining stationary until the end of the war in the summer of 1953.
During the Korean War the 45th Infantry Division suffered 4,004 casualties, consisting of 834 killed in action and 3,170 wounded in action. The division was awarded four campaign streamers and one Presidential Unit Citation. One soldier from the division, Charles George, was awarded the Medal of Honor while serving in Korea.
The division briefly patrolled the Korean Demilitarized Zone following the signing of the armistice ending the war, but most of its men returned home and reverted to National Guard status on 30 April 1954. Its colors were returned to Oklahoma on 25 September of that year, formally ending the division's presence in Korea.
The division remained as a unit of the Oklahoma National Guard, and participated in no major actions throughout the rest of the 1950s save regular weekend and summer training exercises. In 1963, the formation was reorganized in accordance with the Reorganization Objective Army Divisions plan, which saw the establishment of a 1st, 2nd and 3rd Brigade within the division. These brigades would see no major deployments or events, and were deactivated five years later in 1968. That same year, due to the perceived lack of need for so many large formations in the Army National Guard, the 45th Infantry Division was deactivated, as part of a larger move to reduce the number of Army National Guard divisions from 15 to eight, while increasing the number of separate brigades from seven to 18. In its place, the independent 45th Infantry Brigade (Separate) was established. The 45th Infantry Brigade received all of the 45th Division's lineage and heraldry, including its shoulder sleeve insignia. Also activated from division assets were the 45th Field Artillery Group, later redesignated the 45th Fires Brigade, and the 90th Troop Command.
The 45th Infantry Division was awarded eight campaign streamers and one unit award in World War II and four campaign streamers and one unit decoration in the Korean War, for a total of twelve campaign streamers and two unit decorations in its operational history.

- As of 1 August 1950, the division consisted of 698 commissioned officers, 64 warrant officers, and 7,651 enlisted men. Army doctrine dictated a fully manned infantry division at 910 officers, 132 warrant officers, and 17,460 enlisted men. The National Guard at the time was operating at a reduced authorization of 851 officers, 130 enlisted men, and 12,777 enlisted men. See Donnelly 2001, p. 92.
- Fearing political ramifications, Army leaders sought to prevent large numbers of casualties from any one state, and the 45th Infantry Division was an all-Oklahoma organization at the beginning of the war. See: Donnelly 2001, p. 122
- As a result of this effort, two 45th Infantry Division units existed between 1952 and 1953; the mostly Active-duty 45th Infantry Division (AUS) in Korea, and the National Guard 45th Infantry Division (NGUS) in Oklahoma. In practice, the military institutionally recognized the Korea unit as the only "official" division, and most of the returning Oklahoma guardsmen were either separated from the Guard at the end of their enlistments or remained in inactive reserve status.
