Anxious Finns are learning how to survive in the wild in preparation for an invasion by their hostile neighbour

It is Friday night on a forested military base in western Finland. A group of women dressed in camouflage with matching purple beanie hats are sat in a dark tent discussing how their perspectives have changed since Russia’s full-scale invasion of Ukraine.

“I didn’t think it was a real threat that Russia would attack us,” says Sari, 42, who works in sales and lives in a nearby town. But then, she adds: “They attacked Ukraine. I saw that it is possible that we are next.”
