With the rain pouring down and the clouds low, there will be no Russian drones overflying his remote outpost in northern Ukraine, the last one before the frontier.Clutching a monocular and wearing a balaclava that only shows his eyes, the guard proudly shows off his NLAW anti-tank missile launcher.This is where Russia's 90th armored division swept in when the war started on February 24, cutting through Ukrainian territory like a knife through butter.But they were never able to take the city, repelled by fierce Ukrainian resistance even though it was regularly bombed.Inside the well-fortified dugout that was set up after the Russian pullback in April, a border guard in his 30s who goes by the nickname "Lynx" says he thinks there's a "50-50 chance" of a new Russian offensive."
