The Starfleet Medal of Valor was a prestigious decoration awarded to members of the United Federation of Planets.
It was created on reference stardate 1/9604 (circa 2254) by Starfleet Command and was awarded in peace or war time for actions beyond the call of duty. It was stylised set of stars with each representing one of the founding members of the Federations and were attached to a ribbon of diagonal blue and silver stripes.
Lieutenant Commander Marsha Mintaine of the USS Valkyrie was awarded this medal on stardate 2/9704 (circa 2355) for her appeasement of the hill tribes of planet Loris VIII. This was given even though she had faced considerable physical and emotional injury by the natives but her actions prevented the deaths of her fellow officers.
