You can't really compare real life footage to a film.
In terms of actual graphic content, I can. The Raid 2 is far more graphic than any film I've seen, which is a good thing but that's irrelevant. The implication of the video is that he's injured by his mortar blowing up, but nothing is actually shown. If it showed him splattered all over the place, then I wouldn't post it and it wouldn't be on youtube.
Yes it might be real violence, but it's no more graphic than a video of a plane dropping a bomb at a distance.
