Prior to World War II, the Medal of Honor could be awarded for actions not involving direct combat with the enemy; 193 men earned the medal in this way. Most of the peacetime medals were awarded to members of the United States Navy for their actions during boiler explosions, man-overboard incidents, and other hazards of naval service. Given in the list below are the place and date of each recipient's Medal of Honor action, as well as their rank at the time of the action.
