Sorry, wasnt the Bradly blowing up, the building blowing up throws off his aim.

If you watch the original version, a Bradley is pushing that position they are shooting at, Hind comes around and as soon as the AT guy was going to shoot, blew up the Bradley and the blast wave throws off his aim.

I have always wondered why the american's were firing on what must have been their own position at the beginning of the clip (otherwise what was the hind attacking?).

and dead
