Final answer:
The Silver Star is awarded to a person who shows gallantry in action while serving in the Navy or Marine Corps.
Step-by-step explanation:
The medal awarded to a person who, while serving in any capacity with the Navy or Marine Corps, is cited for gallantry in action that does not warrant a Medal of Honor or Navy Cross is the Silver Star.
The Silver Star is the third-highest military decoration for valor in the United States Armed Forces. It is awarded to members of the Navy, Marine Corps, and other branches of the military for acts of valor in combat.
For example, one notable recipient of the Silver Star is Guy Gabaldòn, a Marine who single-handedly captured hundreds of Japanese prisoners of war during the battle for Saipan in World War II.
