One of its first "official" engagements was during the Mexican-American War, where Missouri volunteers fought at the Battles of Embudo Pass and Taos and participated in the occupation of Chihuahua City.[1]
The Missouri National Guard though, officially traces its lineage to theMissouri State Militia, created in 1861 to counter Confederate guerrillas during theAmerican Civil War. Missouri units fought for both Union and Confederate causes. The Confederate1st Missouri Infantry Regiment, later part of the138th Infantry Regiment lineage, fought at Shiloh, Corinth, Iuka, Champion Hill, the Siege of Vicksburg, the Atlanta campaign, Franklin, and Nashville, among other engagements across the Western Theater.
The Missouri Army National Guard was formally organized in 1877. It was first mobilized in theSpanish–American War (1898), raising six volunteer infantry regiments, though none deployed overseas.
In 1916, Missouri Guardsmen were sent to the U.S.–Mexico border at Laredo, Texas during the Mexican Punitive Expedition.[1]

In the Pacific, Missouri units served in theAleutian Islands campaign, mainly the138th Infantry Regiment while other units fought atLeyte andOkinawa, mainly the110th Engineer Regiment. After the war's end, the unit was sent to perform occupation duty in Seoul, Korea. In Europe, the35th Infantry Division fought in the Invasion of Normandy and the Northern France, Rhineland, Ardennes-Alsace, and Central Europe campaigns.
The Missouri Air National Guard was established in 1947 and mobilized for service during the Korean War.[1]
Throughout the Cold War stages, the Missouri Guard was mainly stationed state side and helping with Missouri duties such as the 1922 Poplar Bluff railroad strike, the 1927 St. Louis tornado, and major flooding in 1951–1952 and 1993. Although not mobilized as full units for the Vietnam War, many Missouri Air Guard pilots served on active duty in Southeast Asia.[1]

The same company deployed in the Gulf War, operating EPW Camp 301 in Saudi Arabia.[1]
