Army Distinguished Service Medal

The Distinguished Service Medal (DSM) is a military award of the United States Army that is presented to any person who, while serving in any capacity with the United States military, has distinguished himself or herself by exceptionally meritorious service to the Government in a duty of great responsibility. The performance must be such as to merit recognition for service that is clearly exceptional. Exceptional performance of normal duty will not alone justify an award of this decoration.
Separate Distinguished Service Medals exist for the different branches of the military as well as a fifth version of the medal which is a senior award of the United States Department of Defense. The Army version of the Distinguished Service Medal is typically referred to simply as the "Distinguished Service Medal" while the other branches of service use the service name as a prefix.
