Several execution style murders, including stabbings, shootings, burning people alive, beatings, and a particularly disturbing scene depicting a man being crushed with a sledgehammer. All of the violence is on screen with very little editing around the details. Many other shootouts, bombings, and fights take place, almost every episode. These often end in bloody/sometimes very gory results (often with innocent victims).
Torture of prisoners, mostly by soldiers is implied, but only shown by sound and aftermath.
In a scene in the third episode, a large pig is captured and slaughtered after it is hung up by one leg. A graphic sequence of the animal's throat being cut and blood pouring into a barrel is quite visible.
