Less than three hours by tank across this flat terrain from the Russian border, NATO troops train for battle with the aim of avoiding war. We are here simply taking our part in NATO and we are delivering again NATO’s core business which is collective defense. You know, we’re here defensively but we’re here to fight and defend should the need arise. It’s a scenario that Europe fears could unfold in Estonia and other Baltic states, once part of the Soviet Union, now frontline NATO members. Russia’s 2014 annexation of Crimea rattled the alliance and it’s taking no chances. Estonia has welcomed the NATO deployment, officially known as its enhanced forward presence aimed at deterring Russia from repeating its invasion of Ukraine. 800 British troops make up the bulk of the thousand-strong battle group. These soldiers are just beginning a new six months tour. Estonia has spent a huge amount of money above and beyond their own defense budget to enable this NATO deployment.
