There is quite a bit of blood during fight scenes, but nothing over the top. About as violent as a standard action movie.
Nearly every single gunshot includes blood splattering and spraying but nothing too graphic.
A man uses a sniper rifle to take out multiple soldiers in a room where an interrogation is taking place. The first shot hits the female interrogator with lots of blood spraying (quite graphic) and several other people are shot with some blood shown (not too graphic).
In a slow motion action sequence, Z is shot in the side with blood spraying. Seconds later, he is shot in the head again with blood spraying out of the back of his head. A couple more soldiers and African villagers are violently killed with lots of blood.
The last action sequence in the movie is extremely violent with lots of blood. This is the most violent scene in the movie. It has headshots and body shots at point blank range, brutal stabbings and hand to hand combat. Many people are violently killed.
