Neutral Sweden has launched its biggest war games in two decades with support from NATO countries, drilling 19,000 troops after years of spending cuts that have left the country fearful of Russia's growing military strength.
On the eve of Russia's biggest manoeuvres since 2013, which NATO says will be greater than the 13,000 troops Moscow says are involved, Sweden will simulate an attack from the east on the Baltic island of Gotland, near the Swedish mainland.
"The security situation has taken a turn for the worse," Micael Byden, the commander of the Swedish Armed Forces, said during a presentation of the three-week-long exercise. In 2010, Sweden ended a 109-year-old national tradition by abolishing its military draft, but brought it back this past March in response to a more dangerous neighborhood.
Sweden, like the Baltics, Poland and much of the West, has been deeply troubled by Vladimir Putin's 2014 annexation of Ukraine's Black Sea peninsula Crimea and its support for rebels in eastern Ukraine.
"Russia is the country that affects security in Europe right now with its actions - the annexation of the Crimea and continued battles in eastern Ukraine - so it is clear that we are watching very closely what Russia is doing," Byden said.
Around 1,500 troops from the United States, France, Norway and other NATO allies are taking part in the exercise dubbed Aurora.
Non-NATO member Sweden has decided to beef up its military after having let spending drop from over 2 percent of economic output in the early 1990s to around 1 percent, and is re-introducing conscription.
The armed forces, which at one point could mobilise more than 600,000, stand at just 20,000, with 22,000 more Home Guard volunteers.
NATO generals say the Aurora exercise is not a response to Russian exercises that start on Thursday.
But Byden, speaking as U.S. and French forces displayed mobile surface-to-air missile systems to be deployed during the exercise, stressed the importance of NATO for Sweden.
"We are a sovereign country that takes care of and is responsible for our safety. We do this together with others, ready to both support and receive help," he said.
The United States shipped vehicles by sea from Germany, while France brought others by train. They are to be moved via a classified route to Sweden's east coast for the exercise where U.S. attack helicopters will play the enemy during Aurora.
The government is determined to stick to the country's formal neutrality. Sweden has not fought a war since it clashed with Norway in 1814.
But like its non-NATO neighbour Finland, Sweden has been drawing closer to NATO, allowing closer cooperation with alliance troops, with a view to working together in the event of an armed conflict.
