Why were men shot at dawn by their own side?

Men were shot at dawn by their own side primarily as a form of military justice during World War I and World War II, often for offenses such as desertion, cowardice, or mutiny. Commanders believed that executing soldiers who abandoned their posts would serve as a deterrent to others and maintain discipline within the ranks. This grim practice also reflected the harsh realities of war, where maintaining order and morale was deemed crucial for success in the face of severe conditions. The tragic irony is that many of those executed were suffering from psychological trauma or the extreme stress of combat.
