Did you notice that the tank - immediately after being blown up by a battlefield-sized nuclear weapon - was filled with diesel, re-crewed, and used to tow its own trailer out of the radioactive zone back towards the depot?
I wonder if the RPG weld repair damage is still visible?
Looks like this tank has had several turrets throughout its career. I would guess that if the same turret was still on the tank that the scar would have been welded, ground and repainted. Might not very visible from the outside.
