I never saw anything incoming it just suddenly blew up. And who was the guy that ran away from near it later? I didn’t get that either, maybe there was an accident inside the tank and a shell exploded.

The lack of people and activity around the tanks makes me wonder if they were abandoned after they ran out of diesel and then blown up by the rebels.

After the first tank gets blown up, the track commander pops up out of the background tank and the foreground tank elevates its main gun, traverses left a bit, depresses the gun a bit then traverses left more. I think those tanks are live and not abandoned.
