5.56mm
I don't think that can be real or at least they're not shooting at it with real guns. That's a simple wooden fence behind him with what looks to be a street and stores on the other side of it. Even in China if random civilians were getting shot while simply going about their daily business there would be a stink.
Also, while I would never do it, the soldier holding the target would be relatively safe if I was shooting at it with my scoped Marlin Model 60 .22. I can put 10 shots in a group little bigger than 1” at 25 yards and not much bigger than that at 50 yards.
