1 "F" word
There is a scene showing where Rambo (Sylvester Stallone) has been stabbed by sharp stick and tries to get it out by pushing it through the other side of his body, and he then put gunpowder inside the wound and lights himself to stop internal bleeding. Although it may seem like there will be much gore in this scene, there really isn't that much blood shown.
