Defense Meritorious Service Hat Pin
The Defense Meritorious Service Medal (DMSM) is an award presented in the name of the Secretary of Defense to members of the Armed Forces. It is the third-highest award that the Department of Defense issues, and is awarded to those who distinguish themselves though non-combat meritorious service or achievement, in a joint capacity. Created on November 3rd, 1977 by President Jimmy Carter's Executive Order 12019, it was first awarded to Major Terrell G Covington of the United States Army.
Similar to the Meritorious Service Medal, the DMSM is awarded for multi-service assignments, while the MSM is awarded for service to a specific branch. Subsequent awards are denoted by wearing a bronze Oak Leaf Cluster on the medal or service ribbon.
