A video filmed by pro Russian militiamen at the Donetsk Airport in 2014 shows an incident in which the militants fire one a column of Ukrainian military vehicles with small arms and an anti material rifle, but at one point a tank fires back with accuracy and smokes their position.

The footage was taken while the Ukrainian forces were still in full control of the airport and the pro Russian mercenaries were just moving into conquer it. In this video they are seen in one of the outer maintenance buildings firing at vehicles hauling in supplies to the Ukrainian troops and evacuating wounded.

Eventually, one of the most brutal battles of modern combat occurred at the Donetsk Airport between September 2014 and January 2015. It became known as the 2nd Battle For Donetsk Airport and hundreds died on each side. Fighting was room to room and reportedly, militants were drilling holes in the floor so they could drop grenades down onto their enemies below them. In early 2015, the Ukrainian forces withdrew and the victory was given to the Russian-backed fighters.
