Most action scenes feature minimal blood/injury detail. There's however a scene in which a character is interrogated and it's strongly implied he's been very badly tortured. Blood can be seen coming out of his mouth and his face too is covered in blood. One of his nails is shown briefly getting pulled and he cries in pain.
Violent scenes include exchanges of gunfire, a glass being smashed in a man's face and a soldier hitting a man's face with the butt of a rifle.
There are some scenes in which dead bodies are seen on the ground, in some cases with blood pooled beneath them.
In one instance, a man is found slumped over a desk having seemingly shot himself in the head.
There is a scene where the main character's nails are being ripped off, nothing is shown but you can hear the yell.
