This better quality footage explains a few things to me about why the tank acted like it did. I couldn't tell from the original footage that the front of the tank was what was getting its shit rocked by the autocannon fire. I doubt they had a single unbroken optic on that entire tank. So the driver was likely driving totally blind at the end.

Second, we saw that big bright explosion and it wasn't apparent what it was. I'm guessing it was a high explosive tank shell exploding in the barrel of the tank after the barrel was damaged or the Bradley pieced the barrel and the shell blew up inside the breech.
