Recent incursions into Swedish airspace and territorial waters by Russian planes and submarines has also contributed to a more-intense climate in the country.
On Monday, Prime Minister Stefan Lofven and Sweden's King Carl XVI Gustaf announced the first creation of a Swedish regiment since World War II, located on the island in "a clear signal" of Stockholm's priorities.
The booklet, produced by the Swedish Civil Contingencies Agency (MSB), advises Swedes to stock up on tinned food, bottled water and blankets in addition to planning how they would manage the supply of water, food, heat and communications when public services are not functioning as normal.
While the booklet doesn't specify where an attack might come from, Sweden and other countries in the region have been on high alert since Russian Federation annexed Ukraine's Crimea peninsula in March 2014.More news: Model 3 price hype helps Tesla shares bounce
The Swedish government made a decision to start increasing military spending from 2016, reversing years of declines.
The leaflet gives advice on how to take shelter, what information to trust and describes what an air raid warning sounds like.
In the event of a "heightened state of alert", the pamphlet emphasizes the expectation that everyone can be marshaled for Sweden's "total defense".

Elsewhere in the pamphlet, residents are told what to do in the event of a terror attack, with the booklet saying: "Put your mobile on silent and do not call anyone who may be in the danger area". If the network is overloaded, it may be hard for vital calls to get through.
"Society is vulnerable, so we need to prepare ourselves as individuals", said Dan Eliasson of the Swedish civil contingencies agency, which is in charge of the project. Updates were issued regularly to the general public until 1961, and then to local and national government officials until 1991. "If Sweden is attacked by another country, we will never give up", the booklet says.
"All information to the effect that resistance is to cease is false", it says.
In recent years there has been renewed discussion in Sweden about joining the North Atlantic Treaty Organisation alliance, and the country has reversed military spending cuts, conducting its largest military exercises in more than two decades in September.More news: Markets rise as Beijing and Washington avert trade war
