I mean is it the occasional missing limb or quite a few but not too graphic or is it more of a bayonet to the head full on legs blowing off. If you get what I mean? I want to watch it with my brother, but he's partial to fainting at the sight of blood (too much anyway).
There is a bit of blood but the combat scenes are not that numerous and no where near the levels of bayonets to the face. The most you will get is a small spray of blood from gun shot wounds. He should be fine.
