The Swedish Civil Contingencies Agency (MSB) will issue a new pamphlet on public preparedness and security with guidelines to teach people how to behave in crisis situations, during terror attacks or in the event of war after a 57-year-long break.
"Everyone is obliged to contribute and everyone is needed" in the event of armed conflict sparking up in Sweden, it says, stating that "everyone who lives here and is between the ages of 16 and 70 can be called up to assist in various ways in the event of the threat".
The stark informational document is illustrated with pictures of sirens, warplanes and families fleeing from war.
"Even if Sweden is safer than most countries, threats do exist", said MSB head Dan Eliasson to journalists during a press conference.
It's published by the Swedish Civil Contingencies Agency and also warns the public that key supplies of food, medicine and gasoline could run short if the country were to enter a crisis.
Sweden has not been at war with another country for more than 200 years. "If Sweden is attacked by another country, we will never give up", the booklet says.
