Looks like that guy gets one through the chest and a quick
follow-up head shot.

Frame by frame there's one (tracer, pretty large calibre) round from the
front that exits in the middle of his lower back, he falls over, gets a
rifle bullet through the head from the same direction as the first shot
and and finally a tracer round through the chest which comes from the
left side and that knocks him completely down.

The bullet tracks are all quite clear on frame-by-frame.
