This is a significant blow for the Ukrainian military and the government in Kiev as it pursues what it calls its "anti-terror operation" in the east. Sloviansk has long been the epicentre of the heaviest fighting here, a town taken by the rebels early in this uprising.
Two other Ukrainian helicopters were downed there at the start of May: a reminder that Kiev is not simply facing an amateur group of fighters here.
This has been a week in which the conflict in eastern Ukraine has escalated. After Kiev launched an air-and-ground assault on separatist groups at Donetsk airport to retake control, the rebels have vowed to regroup.
They hold patches of land and are clearly equipped with significant weapons. When Ukraine's new President-elect, Petro Poroshenko, vows to crush what he calls the "terrorists" within "a few hours, rather than a few months", this latest loss of life illustrates the immense challenge he faces.
President Turchynov said the 14 dead included Gen Serhiy Kulchytskiy, head of combat and special training for Ukraine's National Guard.President Turchynov said the 14 dead included Gen Serhiy Kulchytskiy, head of combat and special training for Ukraine's National Guard.
