So this is completely terrifying. In a you will probably pee a little bit as you watch this GIF kind of way. In a holy crap wait a minute this isn't a video game right kind of way. No, no it is not. This is what it looks like to take a direct hit from a tank shell in real life. You can see it blast out of the barrel and head straight for your face.
The GIF shows what looks like a T-72 tank firing a tank shell at the camera. The video was uploaded by Lewaa al-Baraa and supposedly taken at Jobar (outside Damascus, Syria).
