Falling on a grenade is the deliberate act of using one's body to cover a live time-fused hand grenade, absorbing the explosion and fragmentation in an effort to save the lives of others nearby. Since this is almost universally fatal, it is considered an especially conspicuous and selfless act of individual sacrifice in wartime. In United States military history, more citations for the Medal of Honor, the country's highest military decoration, have been awarded for falling on grenades to save comrades than any other single act. In Israel, on the opening day of the October 7 attacks, 9 people threw themselves on grenades, most of them were civilians.
