US officials have confirmed that Ukraine has begun using long-range missiles secretly shipped in recent weeks. They say the missiles were used for the first time in a strike on a Russian airfield in Crimea last week. The “Army Tactical Missile Systems” – or ATACMS – were part of a 300 million-dollar assistance package approved by the United States in March. The US supplied mid-range versions of the system last September. This latest batch can strike targets up to 300 kilometers away. What targets do these long-range ATACMS missiles bring within the range of the Ukrainian military?
