That's what I'm betting too, the driver was asked to put it to the side so something esle could access the garage but they forgot that the cannon extends much further out than the rest of the tank.
I doubt its real. Look at the hole and the angle of the barrel. You would have to start with a lowered barrel and raise it while you drive trough to keep that hole so small.
It might have started with a lowered barrel and there might be a hidden girder under the barrel which raised the whole tank up as the barrel slid forward over that girder. The tank does look like it's leaning back on its suspension.
🤔. If he was driving towards the wall, there would be a larger hole starting from where the top of the gun barrel is. To get such a small hole in the wall as shown in the picture, the driver would have to intentionally articulate the barrels so it enters through the wall at the same position. This doesn't seem likely though, given the angle and position of the gun.
