Something goes flying to the left, too.I say this somewhat seriously, if you look at the upper/right of the screen at about the 8 or 9 sec mark, there is something flying across. I'm pretty sure that's the TC (tank commander). The shape is right. Unless there's a hatch cover or (as we call it) sponson cover roughly that shape.
I thought maybe a piece of the skirt, the armor covering the track, road wheels and idler arms. But I don't think the Russian tanks have that large of panels on the skirt. Plus, unless it was a mine just inside thw track on that side, it wouldn't fly off in that direction.
