What Planet Did This Tank Come From?

What Planet Did This Tank Come From?

There are no details of this tank, which could be from the Soviet Era. The picture finder says that some people suggested it’s a fog/smoke generator but, for its looks, it could be an armoured antimatter cannon.

Why a smoke/fog generator? The finder says it could be a water cannon for “burning oil wells”, but it may as well be a flamethrower. Whatever it is, it looks very menacing. Any idea of what this thing really is? If you have any clue, tell us in the comments. [DRB]
