Soldiers must engage without awaiting orders if anyone were to invade Danish territory, including US troops attempting to seize Greenland, according to a 1952 military directive that Denmark's Defence Ministry has confirmed remains in force.
The standing order requires Danish military personnel to "immediately take up the fight" against any attack on Danish territory without waiting for commands, even if commanders are unaware of a declaration of war, the Defence Command and Ministry told Danish newspaper Berlingske.
