The Combat Readiness Medal is an award of the United States Air Force which was first created in 1964. The original Combat Readiness Medal was an award senior to the Air Force Commendation Medal, and it was awarded for superior and meritorious duty to the United States Air Force. The award criteria for the medal were revised in 1967 and the Combat Readiness Medal adopted the designation as an achievement/service medal. Multiple presentations of the Combat Readiness Medal are authorized, with additional awards denoted by oak leaf clusters.
