Which of the following medals signifies service and sacrifice above and beyond the call of duty?

The Congressional Medal of Honor is the highest military decoration awarded by the United States government. It is specifically given to members of the armed forces for acts of valor that are performed conspicuously above and beyond the call of duty. This prestigious medal symbolizes exceptional bravery and selfless service, often in the face of extreme danger and adversity. Recipients of this honor demonstrate extraordinary courage, commitment, and sacrifice, which sets this medal apart from others that recognize excellence in service, but do not necessarily reach the same level of heroic action.

Other medals, such as the Distinguished Flying Cross, Silver Star, and Bronze Star, recognize commendable service and acts of heroism, but they do not carry the same weight and significance as the Congressional Medal of Honor when it comes to extraordinary service and sacrifice.
