The Distinguished Service Medal (DSM) is a military decoration of the United States Army that is presented to soldiers who have distinguished themselves 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. The exceptional performance of normal duty will not alone justify an award of this decoration.
