The 140th Operations Group is a unit of the Colorado Air National Guard, stationed at Buckley Space Force Base, Aurora, Colorado. If activated to federal service, the group is gained by Air Combat Command of the United States Air Force.
The group was activated as the 370th Fighter Group and served in the European Theater of World War II where it earned two Distinguished Unit Citations and was awarded the Belgian Fourragere after being cited twice in the Order of the Day of the Belgian Army.
In 1946 the group, now redesignated the 140th Fighter Group, was one of the original twenty-seven regular Army Air Forces groups allotted to the National Guard. Since 1950 the group has controlled the operational squadrons of the 140th Wing, except for the period 1974–1993, when the group was inactive.
