Apos is the master of finding extraordinary videos on teh internets...:IS2:
Reminded me of driving a big Cat dozer in the '70's. Release the drive on the tread (pulling on the handle) and standing on the released treads brake pedal to turn. I thinke he needs to work on his gear changing though...

After a while, one learns the quirks of their individual machine and where its shift points (rpm vs speed vs gear) are by feel and sound.
Really cool video with lots of little nuances. Great find and post.
I noticed he turned the turret back around before re-entering his seat. I wonder if that was to put the barrel back to the front of if that was necessary to give him room to climb back in?
