In 1969, the division assumed responsibility for the air defense of Montana, North Dakota, South Dakota, Wyoming, and parts of Nebraska, Utah, Nevada, and Idaho. By 1973, this area included parts of Colorado, Kansas, Oklahoma, Texas, and New Mexico. Tactical units assigned to the 24th participated in numerous training exercises such as Feudal Indian, Vigilant Overview, and Feudal Keynote. Between 1969 and 1979, the division also controlled several radar squadrons. On 1 October 1979, the 24th Air Division became a component of Tactical Air Command, but remained stationed in Montana, and its mission continued to be one of equipping, administering, training, and providing combat ready air defense forces for the operational control of NORAD.

The knight's head in armor is symbolic of the personnel of the unit who stand alert, ever ready and maintain constant watch. The blue field not only symbolizes the sky, but space and the challenge of detecting and defending against threats from space. The stars on the field fo blue represent the 13 original colonies.
