The Medal of Honor is the highest military award given by the U.S. Armed Forces. It was approved by Abraham Lincoln in 1862 and requires that the recipient engage in heroic military action against an enemy of the U.S. or foreign opposing force while serving with friendly forces. There are three guidelines for receiving the award, including engaging the enemy, being in a military conflict with an opposing foreign force, and serving with friendly forces not at war with the opposing armed force.
